Malaria advice covers all of Liberia. Whether you need the yellow fever card depends on your route.
- Travel clinic CDC recommends medicine or vaccines for some areas · which ones
- No CDC travel notice for mosquito-borne disease
The CDC recommends malaria prevention medicine for all of Liberia, from Mamba Point and Sinkor to the surf at Robertsport, in every month. It also recommends yellow fever vaccine for travelers 9 months and older, and Liberia asks for the certificate if you arrive from a country with yellow fever risk.
Are there mosquitoes in Liberia? Yes, all year, and the CDC recommends malaria prevention medicine for the whole country, Monrovia, Robertsport and Harbel included. Whether you're home to see family, posted with an aid group or mission, or in Monrovia for work, the advice for a family home in Sinkor is the same as for a hotel on Mamba Point.
Malaria in every county, and why family visits matter
The CDC's wording is "CDC recommends that travelers going to Liberia take prescription medicine to prevent malaria." Transmission occurs in all areas, mostly chloroquine-resistant Plasmodium falciparum, with no exception for cities, beach towns or the dry season. People going home to see family are the travelers most often caught out. CDC notes that travelers visiting friends and relatives are at higher risk of malaria because they often skip prevention medicine, so the clinic visit belongs on the list for a tenth trip home as much as a first.
Malaria mosquitoes bite from dusk to dawn. Put repellent on at sunset, wear long sleeves in the evening and sleep in an air-conditioned or screened room. Where screens are missing, or a power cut stops the air conditioning, a treated bed net covers the night. Lodges around Robertsport and Lake Piso are likely to see more mosquitoes after dark.
Yellow fever: Grand Cape Mount and the certificate
Liberia confirmed two yellow fever cases in 2025, WHO reported, one from Grand Bassa County and one from Porkpa District in Grand Cape Mount County, the county Robertsport is in. That patient was a miner, probably infected at a mining village, and a May 2026 vaccination campaign reached 135,401 people in Porkpa and neighboring districts. WHO describes Liberia's population immunity as generally high, and its October 5–11, 2026 bulletin lists no open yellow fever event there.
What we suggest you do with this: the CDC recommends malaria medicine for all areas of Liberia, and its yellow fever recommendation is "Vaccine is recommended for all travelers ≥9 months old." Liberia's entry rules read "Direct travel from United States: Vaccine is not required" and "Travel from countries with risk for YF virus transmission: Vaccine is required for travelers ≥1 year old." Book a travel-medicine appointment 4–6 weeks before departure and bring your full route, since a connection through a risk country changes the certificate question. Our malaria-zone checklist covers everything around the prescription.
Daytime biters, rats and the rains
The CDC lists dengue for Liberia, spread by Aedes mosquitoes that bite in daylight, so add a morning coat of repellent, as our dengue & Zika routine explains. The 2026 outbreak WHO's Africa office tracked is Lassa fever, with 32 confirmed cases and 10 deaths in Bong, Grand Bassa and Nimba counties. People catch it from food or air contaminated by infected rats, so keep food sealed.
The one long rainy season runs roughly May to October, heaviest from about June to September, and Monrovia has a reputation as one of the world's wettest capitals. Those peak months tend to bring the most mosquitoes and the hardest roads to Robertsport. The dry season, roughly November to April, tends to be lighter, especially in the Harmattan months of December to February. Malaria medicine applies in every month.
Where you're going
Monrovia: Mamba Point, Sinkor & Congo Town
Inside the CDC's malaria advice with no city exception, from a Mamba Point hotel to a family home in Congo Town. Check the screens when you arrive, and keep a net for nights when the power and the air conditioning go off.
Robertsport
The surf town on the Grand Cape Mount coast, inside the malaria advice. One of the two 2025 yellow fever cases came from Porkpa District in the same county, so take the vaccine question to the clinic.
Harbel & the Firestone plantation
The rubber plantation town by Roberts International Airport, under the same malaria advice. It is rural and green, so the dusk routine matters here as much as in Monrovia.
Crossing into Sierra Leone? It requires yellow fever proof from all travelers; our Sierra Leone briefing has the details.
The Liberia kit
- Picaridin 20% travel sprays: odorless in the humidity and quick to reapply at sunset.
- A full-size backup in the checked bag for a long family visit or a posting upcountry.
- A treated travel bed net for rooms where screens or power fall short.
One more rule outlasts the trip. Any fever during or after your trip means a doctor visit, and you tell them you were in Liberia. That holds for a year after you get home.
Traveler questions
Do I need malaria pills if I'm visiting family in Monrovia?
The CDC recommends malaria prevention medicine for all of Liberia and makes no exception for cities, beach towns or the dry season, so a family home in Monrovia falls under the same advice as a hotel. CDC notes that travelers visiting friends and relatives are at higher risk of malaria because they often skip prevention medicine. Which medicine fits you is a call for a travel clinic, made 4–6 weeks before departure. Our malaria-zone checklist covers the rest of the preparation.
Do I need a yellow fever certificate for Liberia?
Not on a direct flight from the US. CDC lists Liberia's entry rules as "Direct travel from United States: Vaccine is not required" and, for travel from countries with yellow fever risk, "Vaccine is required for travelers ≥1 year old." A connection through a risk country in West Africa can trigger that rule, so carry the certificate if you're connecting. Separately, the CDC recommends the vaccine itself for all travelers 9 months and older.
Was there yellow fever near Robertsport?
One of Liberia's two confirmed 2025 cases came from Porkpa District in Grand Cape Mount County, the county Robertsport is in. WHO said the patient, a miner, was probably infected in the mining village of Vinja, and a vaccination campaign in May 2026 reached 135,401 people in Porkpa and neighboring districts. The other case was in Grand Bassa County. Raise the CDC's vaccine recommendation at your travel clinic visit.
Is there dengue or Zika in Liberia?
The CDC's Liberia page lists dengue, and recent WHO Africa bulletins show no outbreak. The page doesn't list Zika, and CDC's Zika page puts Liberia among areas with the mosquitoes but no reported cases, where its advice to pregnant travelers is "Prevent mosquito bites during and after travel." Dengue's mosquito bites by day, so repellent goes on in the morning as well as at sunset.
