Visiting Belize is Ideal in 2026, But Mosquito-Borne Diseases Are Risky

As the spring season of 2026 transitions into summer vacation planning, Belize is poised to welcome an influx of American visitors, thanks to its dry-season sunshine.

Known for its world-famous Barrier Reef, this Central American country is an ideal destination for snorkelers, divers, and adventure seekers alike.

Belize's tourism sector continues to recover strongly following the pandemic. In 2025, overnight arrivals totaled approximately 551,698, with Americans accounting for about 65-67%—around 372,300 visitors.

However, health officials are advising travelers to take precautions against mosquito-borne illnesses before boarding an airplane, as their activity has varied in recent years. Belize is currently monitoring four key mosquito-borne illnesses: dengue, chikungunya, Zika, and malaria.

Dengue: This is the most common health threat, with official reports showing roughly 232 cases as of March 2026 and 2,794 in 2025. Localized spikes in cases have occurred, particularly in the Belize District. 

Chikungunya: No cases were reported in 2026 and 2025; however, 36 confirmed cases were reported nationwide in 2024.

Zika: There were 31 confirmed cases in Belize in 2024.

Malaria: Belize has maintained malaria-free certification from the World Health Organization since June 2023. Only sporadic imported cases were reported in 2025-2026, with no sustained local transmission.

Additionally, cases of New World screwworm myiasis have been reported in countries where it had previously been eliminated, including Belize.

The U.S. Centers for Disease Control and Prevention (CDC) provides clear guidance for travelers to Belize. No vaccines are required for entry, but routine and travel vaccinations are strongly recommended.

With record levels of U.S. tourism on the horizon and proactive health measures in place, millions of Americans can enjoy safe, memorable trips to Belize. Always check the latest CDC Travelers' Health page for the latest Belize news and consult a travel vaccine provider before departure.

Separately, the U.S. Department of State says, "Visiting Belize: Exercise increased caution in some areas, such as the Southside of Belize City."
