Summary of recommendations
Most travelers to Nigeria will need vaccinations for hepatitis A, typhoid fever, polio, meningococcal meningitis, and yellow fever, as well as medications for malaria prophylaxis and travelers' diarrhea. Other immunizations may be necessary depending upon the circumstances of the trip and the medical history of the traveler, as discussed below. Insect repellents are recommended, in conjunction with other measures to prevent mosquito bites. All travelers should visit either a travel health clinic or their personal physician 4-8 weeks before departure.
Malaria:Prophylaxis with Lariam (mefloquine), Malarone (atovaquone/proguanil), or doxycycline is recommended for all areas.
|Hepatitis A||Recommended for all travelers|
|Typhoid||Recommended for all travelers|
|Yellow fever||Recommended for all travelers. Required for travelers arriving from a yellow-fever-infected area in Africa or the Americas.|
|Meningococcus||Recommended for all travelers|
|Polio||One-time booster recommended for any adult traveler who completed the childhood series but never had polio vaccine as an adult|
|Hepatitis B||Recommended for all travelers|
|Rabies||For travelers spending a lot of time outdoors, or at high risk for animal bites, or involved in any activities that might bring them into direct contact with bats|
|Measles, mumps, rubella (MMR)||Two doses recommended for all travelers born after 1956, if not previously given|
|Tetanus-diphtheria||Revaccination recommended every 10 years|
Travelers' diarrhea is the most common travel-related ailment. The cornerstone of prevention is food and water precautions, as outlined below. All travelers should bring along an antibiotic and an antidiarrheal drug to be started promptly if significant diarrhea occurs, defined as three or more loose stools in an 8-hour period or five or more loose stools in a 24-hour period, especially if associated with nausea, vomiting, cramps, fever or blood in the stool. A quinolone antibiotic is usually prescribed: either ciprofloxacin (Cipro)(PDF) 500 mg twice daily or levofloxacin (Levaquin) 500 mg once daily for a total of three days. Quinolones are generally well-tolerated, but occasionally cause sun sensitivity and should not be given to children, pregnant women, or anyone with a history of quinolone allergy. Alternative regimens include a three day course of rifaximin (Xifaxan) 200 mg three times daily or azithromycin (Zithromax) 500 mg once daily. Rifaximin should not be used by those with fever or bloody stools and is not approved for pregnant women or those under age 12. Azithromycin should be avoided in those allergic to erythromycin or related antibiotics. An antidiarrheal drug such as loperamide (Imodium) or diphenoxylate (Lomotil) should be taken as needed to slow the frequency of stools, but not enough to stop the bowel movements completely. Diphenoxylate (Lomotil) and loperamide (Imodium) should not be given to children under age two.
Most cases of travelers' diarrhea are mild and do not require either antibiotics or antidiarrheal drugs. Adequate fluid intake is essential.
If diarrhea is severe or bloody, or if fever occurs with shaking chills, or if abdominal pain becomes marked, or if diarrhea persists for more than 72 hours, medical attention should be sought.
Though effective, antibiotics are not recommended prophylactically (i.e. to prevent diarrhea before it occurs) because of the risk of adverse effects, though this approach may be warranted in special situations, such as immunocompromised travelers.
Malaria in Nigeria: prophylaxis is recommended for all travelers. Either mefloquine (Lariam), atovaquone/proguanil (Malarone)(PDF), or doxycycline may be given. Mefloquine is taken once weekly in a dosage of 250 mg, starting one-to-two weeks before arrival and continuing through the trip and for four weeks after departure. Mefloquine may cause mild neuropsychiatric symptoms, including nausea, vomiting, dizziness, insomnia, and nightmares. Rarely, severe reactions occur, including depression, anxiety, psychosis, hallucinations, and seizures. Mefloquine should not be given to anyone with a history of seizures, psychiatric illness, cardiac conduction disorders, or allergy to quinine or quinidine. Those taking mefloquine (Lariam) should read the Lariam Medication Guide (PDF). Atovaquone/proguanil (Malarone) is a combination pill taken once daily with food starting two days before arrival and continuing through the trip and for seven days after departure. Side-effects, which are typically mild, may include abdominal pain, nausea, vomiting, headache, diarrhea, or dizziness. Serious adverse reactions are rare. Doxycycline is effective, but may cause an exaggerated sunburn reaction, which limits its usefulness in the tropics.
Long-term travelers who may not have access to medical care should bring along medications for emergency self-treatment should they develop symptoms suggestive of malaria, such as fever, chills, headaches, and muscle aches, and cannot obtain medical care within 24 hours. See malaria for details. Symptoms of malaria sometimes do not occur for months or even years after exposure.
Insect protection measures are essential.
For further information about malaria in Nigeria, including a map showing the risk of malaria in different parts of the country, go to the World Health Organization and Roll Back Malaria.
The following are the recommended vaccinations for Nigeria:
Hepatitis A vaccine is recommended for all travelers over one year of age. It should be given at least two weeks (preferably four weeks or more) before departure. A booster should be given 6-12 months later to confer long-term immunity. Two vaccines are currently available in the United States: VAQTA (Merck and Co., Inc.) (PDF) and Havrix (GlaxoSmithKline) (PDF). Both are well-tolerated. Side-effects, which are generally mild, may include soreness at the injection site, headache, and malaise.
Older adults, immunocompromised persons, and those with chronic liver disease or other chronic medical conditions who have less than two weeks before departure should receive a single intramuscular dose of immune globulin (0.02 mL/kg) at a separate anatomic injection site in addition to the initial dose of vaccine. Travelers who are less than one year of age or allergic to a vaccine component should receive a single intramuscular dose of immune globulin (see hepatitis A for dosage) in the place of vaccine.
Typhoid vaccine is recommended for all travelers. It is generally given in an oral form (Vivotif Berna) consisting of four capsules taken on alternate days until completed. The capsules should be kept refrigerated and taken with cool liquid. Side-effects are uncommon and may include abdominal discomfort, nausea, rash or hives. The alternative is an injectable polysaccharide vaccine (Typhim Vi; Aventis Pasteur Inc.) (PDF), given as a single dose. Adverse reactions, which are uncommon, may include discomfort at the injection site, fever and headache. The oral vaccine is approved for travelers at least six years old, whereas the injectable vaccine is approved for those over age two. There are no data concerning the safety of typhoid vaccine during pregnancy. The injectable vaccine (Typhim Vi) is probably preferable to the oral vaccine in pregnant and immunocompromised travelers.
Yellow fever vaccine is recommended for all travelers greater than nine months of age. The vaccine is required for all travelers greater than one year of age arriving from a yellow-fever-infected country in Africa or the Americas. In Nigeria, yellow fever is reported from the states of Abia, Adamawa, Akwa Ibom, Anambra, Bauchi, Bayelsa, Bendel, Benue, Cross River, Gombe, Imo, Kaduna, Kano, Kwara, Lagos, Niger, Ogun, Ondo, Oyo, Plateau, and Sokoto, but may occur elsewhere. A total of 38 cases were reported for the first five weeks of 2013.
Yellow fever vaccine (YF-VAX; Aventis Pasteur Inc.) (PDF) must be administered at an approved yellow fever vaccination center, which will give each vaccinee a fully validated International Certificate of Vaccination. The vaccine should not in general be given to those who are younger than six months of age, immunocompromised, or allergic to eggs (since the vaccine is produced in chick embryos). It should also not be given to those with a malignant neoplasm and those with a history of thymus disease or thymectomy. Caution should be exercised before giving the vaccine to those who are between the ages of 6 and 8 months, age 60 years or older, pregnant, or breastfeeding. Reactions to the vaccine, which are generally mild, include headaches, muscle aches, and low-grade fevers. Serious allergic reactions, such as hives or asthma, are rare and generally occur in those with a history of egg allergy.
Polio immunization is recommended for all travelers to Nigeria. There has been a recent upsurge in polio cases, especially in the northern part of the country, due to the reluctance of local officials to allow polio immunization. Any adult who received the recommended childhood immunizations but never had a booster as an adult should be given a single dose of inactivated polio vaccine. All children should be up-to-date in their polio immunizations and any adult who never completed the initial series of immunizations should do so before departure. Because of ongoing polio transmission, the World Health Organization recently recommended that those visiting for more than four weeks should receive an additional dose of polio vaccine between 4 weeks and 12 months prior to international travel and have the dose documented in the yellow book (International Certificate of Vaccination). Side-effects are uncommon and may include pain at the injection site. Since inactivated polio vaccine includes trace amounts of streptomycin, neomycin and polymyxin B, individuals allergic to these antibiotics should not receive the vaccine.
Meningococcal vaccine is recommended for all travelers. Meningococcal vaccine has few side-effects. Mild redness at the injection site may occur. Young children may develop transient fever.
Measles vaccine is recommended for any traveler born after 1956 who does not have either a history of two documented measles immunizations or a blood test showing immunity. A measles outbreak was recently reported from Nigeria (see "Recent outbreaks" below). Many adults who had only one vaccination show immunity when tested and do not need the second vaccination. Measles vaccine should not be given to pregnant or severely immunocompromised individuals.
Hepatitis B vaccine is recommended for all travelers if not previously vaccinated. Two vaccines are currently licensed in the United States: Recombivax HB (Merck and Co., Inc.) (PDF) and Engerix-B (GlaxoSmithKline) (PDF). A full series consists of three intramuscular doses given at 0, 1 and 6 months. Engerix-B is also approved for administration at 0, 1, 2, and 12 months, which may be appropriate for travelers departing in less than 6 months. Side-effects are generally mild and may include discomfort at the injection site and low-grade fever. Severe allergic reactions (anaphylaxis) occur rarely.
Rabies vaccine is recommended for travelers spending a lot of time outdoors, for travelers at high risk for animal bites, such as veterinarians and animal handlers, for long-term travelers and expatriates, and for travelers involved in any activities that might bring them into direct contact with bats. Children are considered at higher risk because they tend to play with animals, may receive more severe bites, or may not report bites. A complete preexposure series consists of three doses of vaccine injected into the deltoid muscle on days 0, 7, and 21 or 28. Side-effects may include pain at the injection site, headache, nausea, abdominal pain, muscle aches, dizziness, or allergic reactions.
Any animal bite or scratch should be thoroughly cleaned with large amounts of soap and water and local health authorities should be contacted immediately for possible post-exposure treatment, whether or not the person has been immunized against rabies.
All travelers should be up-to-date on routine immunizations, including
Cholera vaccine is not generally recommended, despite recent outbreaks in Nigeria, because most travelers are at low risk for infection. Two oral vaccines have recently been developed: Orochol (Mutacol), licensed in Canada and Australia, and Dukoral, licensed in Canada, Australia, and the European Union. These vaccines, where available, are recommended only for high-risk individuals, such as relief workers, health professionals, and those traveling to remote areas where cholera epidemics are occurring and there is limited access to medical care. The only cholera vaccine approved for use in the United States is no longer manufactured or sold, due to low efficacy and frequent side-effects.
A cholera outbreak was reported in November 2001, chiefly affecting the states of Kano (Kano metropolis), Jigawa, Kwara (Bode Saadu), and Akwa Ibom (Opkoso health district). As of November 26, a total of 2050 cases and 80 deaths had been reported in Kano State. For details, go to World Health Organization. Previous outbreaks occurred in the states of Kano, Adamawa and Edo in 1999.
An outbreak of Ebola virus disease, a highly contagious and often deadly viral infection, was reported from Nigeria in July 2014, causing 20 probable and suspected cases, eight of them fatal, by September 24 (see the World Health Organization and the Centers for Disease Control).
Those at risk for Ebola include household contacts of other victims, health care providers, and those participating in funeral rites, which usually involve close contact with the body of the deceased. The virus may also be transmitted by eating wild animals and bushmeat, including fruit bats, certain primates, and duikers (small antelopes). Most travelers are at low risk. Those who develop fever or other findings suggestive of Ebola, such as low platelets or elevated liver enzymes, within 21 days of travel to Nigeria, should be tested for Ebola. Healthcare providers should collect serum, plasma, or whole blood. A minimum sample volume of 4 mL should be shipped refrigerated or frozen on ice pack or dry ice (no glass tubes) to the CDC, in accordance with IATA guidelines as a Category B diagnostic specimen. Suspected cases must also be strictly isolated. No travel restrictions are recommended for Nigeria at this time.
An outbreak of Lassa fever was reported from Nigeria in January 2012, causing 1723 suspected cases, 147 laboratory-confirmed cases, and 112 deaths by the end of the year. The outbreak involved 23 of the 36 States. Three doctors and four nurses were reportedly among the fatalities (see the World Health Organization and ProMED-mail). An additional 1195 cases and 39 deaths were recorded for the year 2013. For the first six months of 2014, a total of 820 cases and 28 deaths were reported; Edo state was particularly affected. In January 2014, a hospital outbreak was reported from the northern state of Bauchi: eight doctors became infected after treating a pregnant woman who had the disease. One of the doctors died. In May 2014, six doctors and nurses on staff at the Federal Teaching Hospital, FETHA, Abakaliki, tested positive for Lassa fever after operating on a pregnant woman who was infected with the disease.
Lassa fever is a life-threatening viral infection that is generally acquired by contact with the excreta of infected rodents, but may also be transmitted person-to-person. The incubation period ranges from 1-3 weeks. Initial symptoms may include fever, malaise, headache, cough, nausea, vomiting, diarrhea, and muscle aches. The presence of an extremely sore throat, with white patches on the tonsils, may help distinguish Lassa fever from other infectious diseases. In severe cases, Lassa fever may lead to dangerously low blood pressure, excessive bleeding, fluid around the lungs (pleural effusion), seizures, or inflammation of the brain (encephalopathy). The risk to most travelers is extremely low, unless they have direct contact with Lassa fever patients. Those caring for Lassa fever patients must take appropriate protective measures at all times, including strict respiratory and body fluid precautions.
In February 2011, an outbreak of Lassa fever was reported from Abakaliki, the Ebonyi State capital, causing at least one death. A major outbreak of Lassa fever was reported in February 2009 from the Federal Capital Territory and neighboring Nassarrawa state, resulting in more than 390 suspected cases and at least 55 deaths. At least four cases occurred in health care workers (see ProMED-mail, February 25 and March 5, 2009, and January 29, 2012). In January 2009, a fatal case of Lassa fever was reported in a UK resident who had traveled to Nigeria (see Eurosurveillance. Between March and June 2008, cases of Lassa fever were reported from the states of Edo, Plateau, Lagos, Ogun, Nasarawa, Taraba, Borno, and Anambra. Two cases, both fatal, occurred in medical doctors at the Ebonyi State University Teaching Hospital in March 2008. Cases were also reported in early 2008 in a Nigerian national, working in Nigeria, who was transferred to Germany for medical care, and in a Nigerian physician evacuated to South Africa for further care. For the year 2008, a total of 229 cases of Lassa fever were reported nationwide, of which 30 were fatal (see ProMED-mail, February 18, 2009).
An outbreak of meningococcal disease was reported from Nigeria in February 2009, chiefly affecting the states of Bauchi, Gombe, Katsina, Jigawa, and Yobe. As of May, a total of 47,902 suspected cases and 2148 deaths had been described (see the World Health Organization and ProMED-mail). A previous meningococcal outbreak occurred in March 2004 in Jigwa state, resulting in 327 cases and 46 deaths (see the World Health Organization). An outbreak in 1996 caused more than 17,000 cases and 2500 deaths, chiefly from the states of Kano, Bauchi, Kaduna, Katsina, Kebbi, Sokoto, and Jigawa. Meningococcal vaccine is recommended for all travelers to Nigeria.
There was an upsurge in polio cases in Nigeria several years ago, due to the reluctance of local officials to allow polio immunization. A total of 1129 cases were recorded for the year 2006, chiefly from the northern part of the country (states of Bauchi, Jigawa, Kaduna, Kano and Katsina). The number of cases fell to 116 for the year 2007, but rose to 783 cases for the year 2008 and 388 cases for the year 2009. The rate of polio immunization has risen in recent years. For the year 2013, the number of cases nationwide fell to 53. For further information, go to the World Health Organization and MMWR. A one-time polio booster is recommended for any adult traveler who received the recommended childhood immunizations but never had polio vaccine as an adult. Children should be fully immunized against polio before traveling to Nigeria.
Cholera outbreaks occur regularly in Nigeria. A total of 23,377 cases and 742 deaths were reported nationwide for the year 2011, affecting 23 of the country's 36 states. The most recent outbreaks were reported in January 2012 from the states of Kaduna and Gombe, in September 2011 from the state of Kebbi and in August 2011 from the states of Yobe, Bauchi, Nasarawa, Sokoto, Osun, and Oyo. Outbreaks were reported in June 2011 from the states of Plateau, Gombe and Niger, in April 2011 from the state of Taraba, and in February 2011 from the states of Kogi and Kano. The main symptoms of cholera are profuse watery diarrhea and vomiting, which in severe cases may lead to dehydration and death. Most outbreaks are related to contaminated drinking water, typically in situations of poverty, overcrowding, and poor sanitation. Most travelers are at extremely low risk for infection. Cholera vaccine, where available, is recommended only for certain high-risk individuals, such as relief workers, health professionals, and those traveling to remote areas where cholera epidemics are occurring and there is limited access to medical care. All travelers should carefully observe food and water precautions, as below.
Measles outbreaks are regularly reported from Nigeria. The most recent was reported from Adamawa State in March 2011. In the first eight months of 2010, a measles outbreak caused more than 4700 cases and at least 26 deaths. Bayelsa State was chiefly affected. In May 2008, a measles outbreak was reported from Jigawa State, which apparently spread from the neighboring country of Niger. In December 2007, a measles outbreak occurred in Zaria and environs in the north-central state of Kaduna, killing more than 200 children. In June 2007, a measles outbreak was reported from the northern state of Borno, killing 60 children (see ProMED-mail, June 20 and December 9, 2007; May 20, 2008; January 29, 2010). In February 2005, a measles outbreak was reported from 12 Local Government Areas (LGAs) of Adamawa state, resulting in over 1100 cases, including 76 deaths. Measles outbreaks were also reported from the states of Gombe, Jigawa, Kaduna, Kano, and Kebbi (see the World Health Organization).
All travelers born after 1956 should make sure they have had either two documented measles immunizations or a blood test showing measles immunity. This does not apply to people born before 1957, who are presumed to be immune to measles. Although measles immunization is usually begun at age 12 months, children between the ages of 6 and 11 months who will be traveling to Nigeria should be given a single dose of measles or MMR vaccine. Measles vaccine should not be given to pregnant or severely immunocompromised individuals.
A malaria outbreak was reported in October 2008 from Katsina State in northern Nigeria, causing more than 50,000 cases and more than 400 deaths (see ProMED-mail, October 19, 2008). Malaria prophylaxis and insect protections measures are recommended for all travelers to Nigeria.
A single human case of H5N1 avian influenza ("bird flu") was reported from Nigeria in January 2007. Since February 2006, outbreaks of avian influenza have been reported from poultry farms in almost all of the country’s 37 states and in the Federal Capital Territory. The most recent poultry outbreaks were reported from Katsina, Kano, Kebbi, and Gombe in July 2008.
Most travelers are at extremely low risk for avian influenza, since almost all human cases in other countries have occurred in those who have had direct contact with live, infected poultry, or sustained, intimate contact with family members suffering from the disease. The Centers for Disease Control and the World Health Organization do not advise against travel to countries affected by avian influenza, but recommend that travelers should avoid exposure to live poultry, including visits to poultry farms and open markets with live birds; should not touch any surfaces that might be contaminated with feces from poultry or other animals; and should make sure all poultry and egg products are thoroughly cooked. A vaccine for avian influenza was recently approved by the U.S. Food and Drug Administration (FDA), but produces adequate antibody levels in fewer than half of recipients and is not commercially available. The vaccines for human influenza do not protect against avian influenza. Anyone who develops fever and flu-like symptoms after travel to Nigeria should seek immediate medical attention, which may include testing for avian influenza. For further information, go to the World Health Organization, Health Canada, the Centers for Disease Control, and ProMED-mail.
Onchocerciasis, a parasitic infection that may result in blindness, is highly prevalent. Nigeria is thought to contain more persons infected with onchocerciasis than any other country in the world.
Schistosomiasis may be acquired by swimming, wading, rafting, or bathing in contaminated fresh water. Swimming and bathing precautions are advised (see below).
HIV (human immunodeficiency virus) infection is reported, but travelers are not at risk unless they have unprotected sexual contacts or receive injections or blood transfusions.
Other infections include
Food and water precautions
Do not drink tap water unless it has been boiled, filtered, or chemically disinfected. Do not drink unbottled beverages or drinks with ice. Do not eat fruits or vegetables unless they have been peeled or cooked. Avoid cooked foods that are no longer piping hot. Cooked foods that have been left at room temperature are particularly hazardous. Avoid unpasteurized milk and any products that might have been made from unpasteurized milk, such as ice cream. Avoid food and beverages obtained from street vendors. Do not eat raw or undercooked meat or fish. Some types of fish may contain poisonous biotoxins even when cooked. Barracuda in particular should never be eaten. Other fish that may contain toxins include red snapper, grouper, amberjack, and sea bass.
All travelers should bring along an antibiotic and an antidiarrheal drug to be started promptly if significant diarrhea occurs, defined as three or more loose stools in an 8-hour period or five or more loose stools in a 24-hour period, especially if accompanied by nausea, vomiting, cramps, fever or blood in the stool. Antibiotics which have been shown to be effective include ciprofloxacin (Cipro), levofloxacin (Levaquin), rifaximin (Xifaxan), or azithromycin (Zithromax). Either loperamide (Imodium) or diphenoxylate (Lomotil) should be taken in addition to the antibiotic to reduce diarrhea and prevent dehydration.
If diarrhea is severe or bloody, or if fever occurs with shaking chills, or if abdominal pain becomes marked, or if diarrhea persists for more than 72 hours, medical attention should be sought.
Insect and Tick Protection
Wear long sleeves, long pants, hats and shoes (rather than sandals). For rural and forested areas, boots are preferable, with pants tucked in, to prevent tick bites. Apply insect repellents containing 25-50% DEET (N,N-diethyl-3-methylbenzamide) or 20% picaridin (Bayrepel) to exposed skin (but not to the eyes, mouth, or open wounds). DEET may also be applied to clothing. Products with a lower concentration of either repellent need to be repplied more frequently. Products with a higher concentration of DEET carry an increased risk of neurologic toxicity, especially in children, without any additional benefit. Do not use either DEET or picaridin on children less than two years of age. For additional protection, apply permethrin-containing compounds to clothing, shoes, and bed nets. Permethrin-treated clothing appears to have little toxicity. Don't sleep with the window open unless there is a screen. If sleeping outdoors or in an accommodation that allows entry of mosquitoes, use a bed net, preferably impregnated with insect repellent, with edges tucked in under the mattress. The mesh size should be less than 1.5 mm. If the sleeping area is not otherwise protected, use a mosquito coil, which fills the room with insecticide through the night. In rural or forested areas, perform a thorough tick check at the end of each day with the assistance of a friend or a full-length mirror. Ticks should be removed with tweezers, grasping the tick by the head. Many tick-borne illnesses can be prevented by prompt tick removal.
Insect repellents are ineffective against tsetse flies, which transmit sleeping sickness (African trypanosomiasis). Areas infested with tsetse flies, which are usually known to local inhabitants, should be avoided. Travelers at risk should wear long sleeves and long pants of medium weight fabric in neutral colors that blend with the environment. Also, travelers should avoid riding in the back of open vehicles, since dust may attract tsetse flies, and should take care not to disturb bushes (where tsetse flies rest) during the warmer parts of the day.
Swimming and bathing precautions
Avoid swimming, wading, or rafting in bodies of fresh water, such as lakes, ponds, streams, or rivers. Do not use fresh water for bathing or showering unless it has been heated to 150 degrees F for at least five minutes or held in a storage tank for at least three days. Toweling oneself dry after unavoidable or accidental exposure to contaminated water may reduce the likelihood of schistosomiasis, but does not reliably prevent the disease and is no substitute for the precautions above. Chlorinated swimming pools are considered safe.
Bring adequate supplies of all medications in their original containers, clearly labeled. Carry a signed, dated letter from the primary physician describing all medical conditions and listing all medications, including generic names. If carrying syringes or needles, be sure to carry a physician's letter documenting their medical necessity.Pack all medications in hand luggage. Carry a duplicate supply in the checked luggage. If you wear glasses or contacts, bring an extra pair. If you have significant allergies or chronic medical problems, wear a medical alert bracelet.
Make sure your health insurance covers you for medical expenses abroad. If not, supplemental insurance for overseas coverage, including possible evacuation, should be seriously considered. If illness occurs while abroad, medical expenses including evacuation may run to tens of thousands of dollars. For a list of travel insurance and air ambulance companies, go to Medical Information for Americans Traveling Abroad on the U.S. State Department website. Bring your insurance card, claim forms, and any other relevant insurance documents. Before departure, determine whether your insurance plan will make payments directly to providers or reimburse you later for overseas health expenditures. The Medicare and Medicaid programs do not pay for medical services outside the United States.
Pack a personal medical kit, customized for your trip (see description). Take appropriate measures to prevent motion sickness and jet lag, discussed elsewhere. On long flights, be sure to walk around the cabin, contract your leg muscles periodically, and drink plenty of fluids to prevent blood clots in the legs. For those at high risk for blood clots, consider wearing compression stockings.
Avoid contact with stray dogs and other animals. If an animal bites or scratches you, clean the wound with large amounts of soap and water and contact local health authorities immediately. Wear sun block regularly when needed. Use condoms for all sexual encounters. Ride only in motor vehicles with seat belts. Do not ride on motorcycles.
Ambulance and Emergency Services
For a medical emergency in Nigeria, call Critical Rescue International at 0802 888 (website http://www.crinigeria.com/) or International SOS in Port Harcourt at 234 84 611 436 /437/623. The CRI ambulances carry Advanced Life Support equipment and are staffed by trained paramedics.
Some of the private and non-profit medical facilities offer acceptable medical care for routine problems, but the quality of the government facilities falls far below Western standards. The training of most physicians is not comparable to that in Western countries. Equipment is poorly maintained. Essential medications and supplies are often unavailable. Most pharmaceuticals and medical supplies are imported, chiefly from Europe.
For medical emergencies, many expatriates go to Saint Nicholas Hospital (57 Campbell Street, Lagos Island, Lagos; ph. 635576, 631739; website http://www.saintnicholashospital.com/). The facility is "rudimentary", according to the U.S. Embassy, but is recommended by Embassy personnel. Services include a 24-hour emergency room, general medicine, general surgery, orthopedics, obstetrics, gynecology, a dialysis unit, and a laboratory. For cardiac problems, the Cardiac Centre (12A, Idowu Martins Street, Victoria Island, Lagos; ph. 234 1 262 1234, 261 0445/7) offers non-invasive cardiac testing, two ICU ward beds, and an emergency room.
Many expatriates also go to International SOS, which operates clinics in Lagos, Port Harcourt, Warri, and Onne:
Travel medical services such as immunizations are provided by Dr. Funmi Alakija (Q-Life Family Clinic, 867A, Bishop Aboyade Cole Street, Lagos 101241; ph. 234-1-8042000, 234-1-4448071/2). In Nnewi, Anambra State, medical services for travelers are provided by Dr. Amobi Ilika, Medical Consultant, Community Medicine Department, Christian Hospital Umuezeani Ozubulu Anambra State (ph. 234 8034 743 775; e-mail: email@example.com; by appointment or walk-in; payment in cash only).
For an excellent introduction to medical care in Nigeria, including an online list of physicians, hospitals, and emergency services, go to the U.S. Embassy website. Most doctors and hospitals will expect payment in cash, regardless of whether you have travel health insurance. Serious medical problems will require air evacuation to a country with state-of-the-art medical facilities.
Traveling with children
Before you leave, make sure you have the names and contact information for physicians, clinics, and hospitals where you can obtain emergency medical care if needed (see the U.S. Embassy website).
All children should be up-to-date on routine childhood immunizations, as recommended by the American Academy of Pediatrics. Children who are 12 months or older should receive a total of 2 doses of MMR (measles-mumps-rubella) vaccine, separated by at least 28 days, before international travel. Children between the ages of 6 and 11 months should be given a single dose of measles vaccine. MMR vaccine may be given if measles vaccine is not available, though immunization against mumps and rubella is not necessary before age one unless visiting a country where an outbreak is in progress. Children less than one year of age may also need to receive other immunizations ahead of schedule (see the accelerated immunization schedule).
Because yellow fever vaccine is not approved for use in children less than nine months of age, children in this age group should not in general be brought to Nigeria.
Because of a recent measles outbreak, consider giving an initial dose of measles vaccine to children between the ages of 6 and 11 months who will be traveling to Nigeria, even though measles immunization is usually not begun until age 12 months.
The recommendations for malaria prophylaxis are the same for young children as for adults, except that (1) dosages are lower; and (2) doxycycline should be avoided. DEET-containing insect repellents are not advised for children under age two, so it's especially important to keep children in this age group well-covered to protect them from mosquito bites.
When traveling with young children, be particularly careful about what you allow them to eat and drink (see food and water precautions), because diarrhea can be especially dangerous in this age group and because the vaccines for hepatitis A and typhoid fever, which are transmitted by contaminated food and water, are not approved for children under age two. Baby foods and cows' milk may not be available in developing nations. Only commercially bottled milk with a printed expiration date should be used. Young children should be kept well-hydrated and protected from the sun at all times.
Be sure to pack a medical kit when traveling with children. In addition to the items listed for adults, bring along plenty of disposable diapers, cream for diaper rash, oral replacement salts, and appropriate antibiotics for common childhood infections, such as middle ear infections.
Travel and pregnancy
Because of the risk of malaria and yellow fever, pregnant women should not in general travel to Nigeria. Yellow fever vaccine is not approved for use during pregnancy, because it contains live virus. Malaria may cause life-threatening illness in both the mother and the unborn child. None of the currently available prophylactic medications is 100% effective. Mefloquine (Lariam) is the drug of choice for malaria prophylaxis during pregnancy, but should not be given if possible in the first trimester. If travel to areas with malaria and yellow fever is unavoidable, insect protection measures must be strictly followed at all times. The recommendations for DEET-containing insect repellents are the same for pregnant women as for other adults.
