Malaria present — chemoprophylaxis commonly recommended

The Solomon Islands have year-round malaria transmission throughout the country (predominantly P. vivax, with chloroquine-resistant P. falciparum). Malaria chemoprophylaxis (atovaquone-proguanil, doxycycline, or mefloquine) is commonly recommended in addition to strict mosquito protection. Discuss the right regimen with your travel medicine specialist before departure.

Yellow fever certificate if arriving from a risk country

There is no yellow fever in the Solomon Islands, but a valid YF vaccination certificate is required on entry for travelers arriving from a country with risk of yellow fever transmission (generally those aged 9 months and over). Direct travel from Switzerland is not affected.

Vaccines

VaccineRecommendationReference
Routine vaccines

Make sure you are up-to-date on all routine vaccines before every trip — per the Swiss BAG schedule. These include:

BAG Impfplan
Dengue

Qdenga® vaccination currently recommended only for travelers with documented prior dengue infection who will be exposed in a region with high dengue transmission.

—
Hepatitis A

Recommended for all travelers to tropical and subtropical countries. Note for Swiss travelers: Hepatitis A is not part of the routine Swiss BAG childhood schedule, so most adult travelers will need vaccination.

CDC Yellow Book
Hepatitis B

Recommended given local prevalence and limited healthcare. Routine in the Swiss BAG childhood schedule since 1998, so younger travelers are usually already covered.

CDC Yellow Book
Rabies

Consider for long stays, remote travel, those working with animals, and small children. Post-exposure care can be hard to obtain quickly on outer islands.

CDC Yellow Book
Typhoid

Recommended for travel to the Solomon Islands, particularly for rural travel, longer stays, visiting friends and relatives, or staying in poor hygienic conditions.

Disease-specific guidance

Malaria

Moderate

Year-round transmission throughout the country, including the main islands and Honiara. Predominantly P. vivax (about 70%) with chloroquine-resistant P. falciparum (about 30%) and rare P. ovale. Chemoprophylaxis is commonly recommended alongside strict mosquito protection.

Risk area
Throughout the country, all islands
Species
P. vivax (~70%), P. falciparum (~30%)
Resistance

Prevention
Chemoprophylaxis + mosquito protection

Yellow fever

None

No yellow fever risk in country. A YF vaccination certificate is required on entry for travelers arriving from a country with risk of yellow fever transmission. Direct travel from Switzerland is not affected.

Dengue

Moderate

Endemic with year-round risk and periodic outbreaks. Daytime mosquito-bite prevention is the main protection and also reduces Zika risk.

Distribution
Throughout the islands
Season
Year-round
Mosquito
Aedes aegypti — bites during daytime

General prevention

Food & water

Use bottled or filtered water, avoid ice from unverified sources, and pay attention to food hygiene. Standard tropical precautions reduce risk of traveler's diarrhea, hepatitis A, and typhoid — particularly relevant for rural travel and stays outside the main resorts.

Mosquito protection

Round-the-clock mosquito protection is important. Daytime-biting Aedes mosquitoes transmit dengue and Zika, while night-biting Anopheles transmit malaria throughout the islands. Use DEET or picaridin repellent, cover up at dawn and dusk, and sleep under an insecticide-treated bed net in rural and lowland areas.
