The Church of Tuvalu, (Te Ekalesia Kelisiano Tuvalu) has historic ties to the Congregational Church and other churches in Samoa, and has the largest number of followers. All nine island groups have traditional chiefs who are members of the Church of Tuvalu. Most followers of other religions or denominations are found in Funafuti, the capital, with the exception of the relatively large proportion of followers of the Bah Faith on Nanumea Island. Missionaries are present and operate freely.
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.
Funafuti is the capital of Tuvalu. It is a true atoll that consists of 30 islands, or motu, as called by the Tuvaluans, surrounding a lagoon 20 kilometres north to south by 11 kilometres east to west.
