Staying Healthy During Your Trip

Prevent Insect Bites

Many diseases, like malaria and dengue, are spread through insect bites. One of the best protections is to prevent insect bites by:

• Using insect repellent (bug spray) with 30%-50% DEET. Picaridin, available in 7% and 15% concentrations, needs more frequent application. There is less information available on how effective picaridin is at protecting against all of the types of mosquitoes that transmit malaria.
• Wearing long-sleeved shirts, long pants, and a hat outdoors.
• Remaining indoors in a screened or air-conditioned area during the peak biting period for malaria (dusk and dawn).
• Sleeping in beds covered by nets treated with permethrin, if not sleeping in an air-conditioned or well-screened room.
• Spraying rooms with products effective against flying insects, such as those containing pyrethroid.

For detailed information about insect repellent use, see Insect and Arthropod Protection.

Be Careful about Food and Water

• Wash your hands often with soap and water, especially before eating.  If soap and water are not available, use an alcohol-based hand gel (with at least 60% alcohol).
• Drink only bottled or boiled water, or carbonated (bubbly) drinks in cans or bottles.  Avoid tap water, fountain drinks, and ice cubes.  If this is not possible, learn how to make water safer to drink.
• Do not eat food purchased from street vendors.
• Make sure food is fully cooked.
• Avoid dairy products, unless you know they have been pasteurized.

Diseases from food and water often cause vomiting and diarrhea. Make sure to bring diarrhea medicine with you so that you can treat mild cases yourself.

Avoid Injuries

Car crashes are a leading cause of injury among travelers. Protect yourself from these injuries by:

• Not drinking and driving.
• Wearing your seat belt and using car seats or booster seats in the backseat for children.
• Following local traffic laws.
• Wearing helmets when you ride bikes, motorcycles, and motor bikes.
• Not getting on an overloaded bus or mini-bus.
• Hiring a local driver, when possible.
• Avoiding night driving.

Other Health Tips

• To avoid animal bites and serious diseases (including rabies and plague) do not handle or pet animals, especially dogs and cats, If you are bitten or scratched, wash the wound immediately with soap and water and seek medical attention to determine if mediation or anti-rabies vaccine is needed.
• To avoid infections such as HIV and viral hepatitis do not share needles for tattoos, body piercing, or injections.
• To reduce the risk of HIV and other sexually transmitted diseases always use latex condoms.
• To prevent fungal and parasitic infections, keep feet clean and dry, and do not go barefoot, especially on beaches where animals may have defecated.

Other Diseases Found in East Africa

Risk can vary between countries within this region and also within a country; the quality of in-country surveillance also varies.

The following are disease risks that might affect travelers; this is not a complete list of diseases that can be present. Environmental conditions may also change, and up to date information about risk by regions within a country may also not always be available.

Dengue, filariasis, leishmaniasis, and onchocerciasis (river blindness) are other diseases carried by insects that also occur in East Africa. African trypanosomiasis (African sleeping sickness) has increased in Africa (it is epidemic in Angola, Democratic Republic of the Congo, and the Sudan; and highly endemic in Cameroon, Central African Republic, Chad, Congo, Cote d'Ivoire, Guinea, Mozambique, Uganda, and Tanzania; low levels are found in most of the other countries), and an increase in travelers has been noted since 2000.  Most had exposures in Tanzania and Kenya, reflecting common tourist routes.  Protecting yourself against insect bites will help to prevent these diseases.

Plague occurs sporadically or in outbreaks.  Outbreaks have occurred since 2000 in Madagascar, Malawi, Mozambique, Uganda, and Tanzania.  Ituri Distric (Oriental Province) in the Democratic Republic of the Congo reports about 1,000 cases per year and was the site of an outbreak in 2006.

Schistosomiasis, a parasitic infection, can be contracted in fresh water in this region. Do not swim in fresh water (except in well-chlorinated swimming pools) in these countries. (For more information, please see Swimming and Recreational Water Safety.)

Polio outbreaks were reported in several previously polio-free countries in Central, Eastern, and Western Africa beginning in 2003.  Polio is still endemic in Nigeria.

Many countries in this region have high incidence rates of tuberculosis and high HIV prevalence rates.

Highly pathogenic avian influenza (H5N1) has been found in poultry populations in several countries in Africa. Avoid all direct contact with birds, including domestic poultry (such as chickens and ducks) and wild birds, and avoid places such as poultry farms and bird markets where live birds are raised or kept.  For a current list of countries reporting outbreaks of H5N1 among poultry and/or wild birds, view updates from the World Organization for Animal Health (OIE), and for total numbers of confirmed human cases of H5N1 virus by country see the World Health Organization (WHO) Avian Influenza website.
