Travellers are recommended to take out full medical insurance before departure. Tuvalu's only hospital is in Funafuti; the outer islands only have trained nurses. More serious and complicated problems may require medicinal evacuation to Fiji or Australia.
Food and drink:
All water is stored in tanks and supply is limited so visitors are advised to use water sparingly and take local advice.
Other risks:
Vaccinations against tuberculosis and hepatitis B are sometimes advised.
