MALARIA: Zanzibar is not an official Malaria area anymore. It is up to you to take Malaria prophylaxis or not. Do bring Mosquito repellent and drink lots of Tonic water (Mosquitos hate the smell of chinine in the tonic water which your skin somehow gives off). If you drink alcohol, enjoy a gin tonic at sunset (gin also contains chinine = double dose of chinine) – the gin tonic is only to keep the Mosquitos away of course. In the hotel rooms, you have mosquito nets and staff usually spray the rooms at night when they get your bed ready. YELLOW FEVER VACCINATION: Yellow Fever vaccination is not compulsory for visitors arriving directly into Tanzania from NON-endemic countries like Europe, the USA and Japan. Tanzania is mapped by the World Health Organization (WHO) as a low risk country for Yellow fever (WHO 2015 update). However, the presence of Yellow fever vector (mosquitoes) poses potential risk for Yellow fever if the virus is introduced into the country. All visitors from Non-Endemic countries, whom on their way to Tanzania have passed through Endemic Yellow Fever zone(s) but they did not get out of that country’s airport, will not require Yellow Fever vaccination certificate provided the transit time at the airport is less than 12 hours. In order to conform to International Health Regulations requirement and safeguard public health security in Tanzania, Yellow fever vaccination is mandatory to travellers arriving from Yellow fever endemic countries. This condition also applies to travellers subjected to long flight connection (transit) in an airport of a Yellow fever endemic country for twelve hours (12hrs) or more. All visitor from Endemic Yellow Fever zone(s), and those visitors whom on their way to Tanzania have passed through Endemic Yellow Fever zone(s) and get out of that country’s airport, will be required to show their yellow fever certificates on their arrival into Tanzania or receive vaccination at the entry point on their arrival (vaccination fee is US $ 50). All visitors from Tanzania mainland to Zanzibar will not be required to show their yellow fever vaccination certificate because Zanzibar is inside the United Republic of Tanzania
