Yellow Fever – A viral disease that occurs primarily in sub-Saharan Africa and tropical South America, yellow fever is transmitted to humans through the bite of infected mosquitoes. The virus is also present in Panama and Trinidad and Tobago. Yellow fever vaccination is recommended for travellers to endemic areas. It may be required to cross certain international borders (for country-specific requirements, see Yellow Fever Vaccine Requirements and Information on Malaria Risk and Prophylaxis, by Country). Vaccination should be given 10 days before travel and repeated at 10-year intervals if there is an ongoing risk.
A certificate of yellow fever vaccination is required for entry into Tanzania when arriving from countries where yellow fever is present.

Hepatitis A or immune globulin (IG) – Transmission of the hepatitis A virus can occur through direct person-to-person contact; exposure to contaminated water, ice, or shellfish harvested from contaminated water; or consumption of fruits, vegetables, or other uncooked foods that were contaminated during harvesting or subsequent handling.
Hepatitis B – Recommended especially if you may be exposed to blood or body fluids (for example, healthcare workers), have sexual contact with the local population, or receive medical treatment. The hepatitis B vaccine is now recommended for all infants and for children aged 11–12 years who did not receive the series as infants.
Malaria – Your risk of malaria may be high in all countries in East Africa, including cities. All travellers should take one of the following drugs (consult your doctor before making a decision):
Meningococcal (meningitis) – Recommended if you plan to visit countries in this region that experience epidemics of meningococcal disease between December and June.
Rabies – Pre-exposure vaccination is recommended if you may have extensive unprotected outdoor exposure in rural areas, such as during camping, hiking, cycling, or certain occupational activities.
Typhoid – Typhoid fever can be contracted through contaminated drinking water or food, or by consuming food or beverages prepared or handled by an infected person. Large outbreaks are most often linked to faecal contamination of water supplies or food sold by street vendors.
Also recommended, as needed: booster doses for tetanus-diphtheria, measles, and a one-time polio vaccine booster for adults.
Ensure your food and drinking water are safe. Foodborne and waterborne diseases are the primary cause of illness in travellers. Travellers’ diarrhoea can be caused by viruses, bacteria, or parasites, which are found throughout East Africa and can contaminate food or water. Infections may cause diarrhoea and vomiting (E. coli, Salmonella, cholera, and parasites), fever (typhoid fever and toxoplasmosis), or liver damage (hepatitis).
