Bocas del Toro takes a clinic visit, a daytime habit and a towel for the sand.

Yes. The day-biting mosquito that spreads dengue lives here, the Bocas region had one of Panama's highest dengue rates from January to April 2026, and the CDC recommends malaria prevention medicine for the whole province in every month. The bite most visitors remember is the chitra, a tiny midge that works the beaches of Isla Colón and Bastimentos at dawn, at dusk and whenever the wind drops.

Malaria advice and winter dengue

The CDC's Panama page lists "the provinces of Bocas del Toro, Chiriquí, Colón, Darién, Panamá, Panamá Oeste, and Veraguas" among its malaria transmission areas, and reports "no malaria transmission in the Canal Zone or in Panama City." For Bocas del Toro, its recommended prevention options are "Atovaquone-proguanil, chloroquine, doxycycline, mefloquine, primaquine, tafenoquine." Panama's malaria count is falling, with 5,298 cases nationally through late August 2026 against 7,758 a year earlier, Telemetro reported, citing the health ministry, and Bocas del Toro isn't among the areas officials call endemic. The CDC's advice still covers the province year-round.

Dengue here ran highest from January to April 2026, ahead of the Pacific side's rainy season. Health ministry figures reported in the Panamanian press put the Bocas del Toro region at close to 200 confirmed cases by mid-April 2026, the second-highest rate in the country after Herrera. Nationally, cases jumped again from late June, to 11,772 suspected by mid-September, more than in all of 2025, the Pan American Health Organization reported. Aedes bites in daylight, so repellent goes on over sunscreen in the morning, after every swim and before late afternoon. Our dengue & Zika routine has the full schedule. The CDC does not recommend yellow fever vaccine for Bocas del Toro, which lies west of the Canal.

Chitras on Isla Colón and Bastimentos

Chitras is the local name for tiny biting midges, the no-see-ums of the US, often called sand flies here. The traveler reviews below, from Playa Estrella and an overwater lodge on Bastimentos, describe heavy biting. Chitras come out at dawn, at dusk and in still air and go for ankles and lower legs, and they are weak fliers, so a breeze grounds them. Our sand fly guide explains the insect.

Sit on a towel or a lounger rather than the sand, spray feet, ankles and calves before you go, and pick a breezy beach on calm days. From late afternoon, light trousers and long sleeves cover the chitras, the second dengue peak and the evening malaria hours. At night, use a bed net or a screened, air-conditioned room. Forest trails inside Bastimentos tend to add mosquitoes and phlebotomine sand flies, a different insect that bites from dusk to dawn and can spread leishmaniasis, a skin infection. See a doctor about any bite sore that won't heal after the trip.

Where you're going

Scores are for a December–April trip. The disease picture is the same at every stop; the bites change with the beach and the breeze.

The Panama briefing covers Panama City and San Blas, and our Costa Rica briefing covers the other side of the border.

What travelers report

Paraphrased from traveler reviews and linked so you can read them in full. One is from an October trip in 2016 and the other is undated, so read them for where chitras bite rather than for this season.

• Playa Estrella (Starfish Beach), Bocas del Toro · October · 2016

  A reviewer warned that the sand is full of sand flies and that the bites were severe, advising visitors to bring a towel, though they still liked the beach. TripAdvisor ↗

• Eclypse de Mar, Isla Bastimentos, Bocas del Toro

  Guests at this overwater lodge said chitras (tiny biting midges) were everywhere and they ended up with more than a hundred bites between them, after staff had told them there was nothing to worry about. TripAdvisor ↗

One rule outlasts the trip. Any fever during your trip or in the year after it means a doctor visit, and you tell them you were in Bocas del Toro. Dengue usually shows up within two weeks; malaria can take longer.
