One of the most common concerns for travellers headed to Africa is how to avoid getting sick. There is a misconception that Africa is loaded with awful diseases. You will be fine. The truth is - common sense is the key to having a great experience and with a couple basic shots, and a few safety measures, you can have a great experience - many people do.

Here is what you should do
Wash your hands with soap and hot water
Drink bottled, boiled or filtered water
Eat cooked food and fruit and
vegetables you have peeled
Avoid mosquito bites at all costs, even though sometimes this is impossible. Here is the best advice on avoiding those buggers:
Be extra careful from dusk to dawn
Wear long-sleeved shirts, pants, and hats
Use repellent with DEET.
Make sure to apply it to all exposed areas right before dusk.
Sleep under a bed net
Use condoms when having sex here

Here is what you should not do
Don't worry about food if you stay in a safari lodge, you should be fine.
Don't eat food purchased from food vendors.
Don't eat dairy products that aren't pasteurized.
Don't drink beverages with ice.
Don't go out without taking the repellent with you
Don't forget to use condoms when having sex

Common Sense
Much of your health depends upon your behaviour and clothes. If you follow the basic rules above and bring few things along you should be fine:
Repellent with DEET
Bed nets (can be bought in Tanzanian cities)
Antidiarrheal medicine
Basic aspirin
Sunblock, sunglasses
Iodine tablets and/or water filters

Immunisation
Visitors from countries infected with cholera and yellow fever must produce international certificates of vaccination. Recommended vaccinations are against hepathitis A, B, polio and typhoid. It is essential for visitors to be informed about malaria prophylaxis.

Modern medical services
are available in Dar es Salaam and other major centres.There are only a limited number of chemists in the country, so visitors are advised to bring their own medicines with them.
