Safety and health

Guinea-Bissau requires a yellow-fever vaccination certificate for arriving travellers aged 1 and over, and vaccination is recommended for travellers aged 9 months and over (cdc.gov).
Malaria prevention is strongly advisable. Discuss suitable prophylaxis with a clinician, use repellent and long clothing, and sleep under insecticide-treated netting where needed (wikivoyage.org).
Protect yourself from mosquitoes, ticks and sand flies because Zika, African tick-bite fever and leishmaniasis occur in the country. Pregnant travellers should take particular care to avoid mosquito bites because of Zika risk (cdc.gov).
Avoid swimming, wading or bathing in freshwater streams, rivers, ponds, lakes and untreated pools because of schistosomiasis. Drink bottled or properly filtered water (cdc.gov | wikivoyage.org).
Avoid contact with stray dogs, cats, monkeys and bats. Seek urgent medical care after any bite or scratch because rabies treatment access may be limited (wikivoyage.org).
The country remains under military-led transitional rule after the 2025 coup, with further elections planned for December. Avoid demonstrations, political gatherings and military or government installations, and monitor local developments.

Recent News

1-2 September 2026: Provisional results showed that Guinea-Bissau approved a new constitution with about 70% support. The changes expand presidential powers, reduce parliament from 102 to 65 seats and reshape electoral rules ahead of December’s planned elections. The result follows a military takeover and opposition calls to boycott the referendum, so political tensions may remain elevated in Bissau (apnews.com | theguardian.com).
