It is important that you consult with your doctor about traveling to Tanzania. That said, the exposure to health risks where we operate is limited. Malaria presents the greatest potential health risk and antimalarial drugs are recommended. The antimalarial drug Malarone may be the best choice, again, consult your doctor.
A Yellow Fever vaccination is required only if you are entering Tanzania from a Yellow Fever infected country, such as Kenya, Ethiopia and Uganda. A Yellow Fever vaccination is not required when flying non-stop to Arusha or Dar es Salaam from the US and Europe.
Other health risks are a non-issue if you drink bottled water only.
