Do you need to take malaria tablets for Zanzibar?
Not necessarily. Tanzania is a high-risk destination for malaria, and if you're on a hunting trip in mainland Tanzania, then yes, you'll need to take anti-malarials. According to the World Health Organization's 2022 report, the prevalence of malaria in Zanzibar is less than 1%. This means that technically you do not need to take anti-malarials when visiting Zanzibar.
However, many Zanzibar vacations include visits to iconic safari destinations such as the Serengeti and Ngorongoro Crater, so travelers need to be prepared and malaria prophylaxis is recommended.
Ask your local travel clinic or doctor for advice on how to prevent contracting malaria while traveling in Tanzania. There are many effective anti-malarial prophylaxis available today. Some anti-malarial treatments need to be started before traveling, so consult a medical professional in advance.
