Yellow fever — entry certificate if arriving from a risk country

There is no yellow fever risk in São Tomé & Príncipe, and the vaccine is generally not recommended for direct travel from Switzerland. However, a valid certificate is required for travelers aged 9 months and older arriving from (or transiting through) a yellow-fever-risk country — relevant if your itinerary includes mainland Central or West Africa.

Hepatitis B

Consider per individual risk and stay duration. Routine in Swiss childhood schedule since 1998 — younger travelers usually covered.

General prevention

Food & water

Use bottled or reliably treated water, avoid ice and raw produce, and eat thoroughly cooked food. These measures reduce traveler's diarrhea, hepatitis A, and typhoid.

Mosquito protection

Mosquito-bite prevention is essential. Malaria risk has declined significantly thanks to sustained control efforts but remains present country-wide. Use DEET or picaridin repellent, cover up at dawn and dusk, and sleep under an insecticide-treated net.
