Tanzania is a stunning destination, but it’s important to take health precautions before you go. Consult your doctor or a travel clinic about recommended vaccinations, including Yellow Fever, which is required if you're arriving from or transiting through a Yellow Fever-endemic country.
Since malaria is present in many parts of Tanzania, taking anti-malarial medication is recommended. Use mosquito repellent and wear long sleeves, especially in the evening. Bringing a basic first aid kit, including any prescription medications, is also wise, as access to medical facilities can be limited in remote areas.
Finally, consider purchasing travel insurance with medical coverage. Make sure it includes any planned activities, such as trekking or safaris, and provides emergency evacuation options in case of unexpected situations.
