Honest about the risks, and specific about what prevents each one.
Oropouche
CDC currently posts an Oropouche travel health notice covering Panama, noting areas in several countries are reporting a low number of cases and that it is spread primarily through the bites of infected midges — small flies — and mosquitoes. The Government of Canada lists Oropouche virus disease as a risk in Panama, describes the midge as a no-see-um, lists fever, headache, joint and muscle pain and chills among the symptoms with aseptic meningitis in some cases, says most travellers are at low risk, and flags concern about transmission from a pregnant person to their unborn baby.
Prevention There is no vaccine and no preventive medication. Repellent on exposed skin, and a sealed or air-conditioned room with fine-mesh screens rather than relying on a standard net. If you are pregnant or planning to be, discuss it with us before you book — the Government of Canada says a healthcare provider may advise avoiding non-essential travel to an area with an outbreak.
Dengue
Named by both sources. The Government of Canada notes the mosquitoes that carry it typically bite in the daytime, particularly around sunrise and sunset, that the level of risk varies with season, year, region and elevation, and that dengue can become severe and be fatal.
Prevention No vaccine or medication to prevent it is available in Canada. Repellent through the day, reapplied — including in Panama City, where malaria is not a risk but dengue is.
Zika
A risk in Panama according to both sources. Spread by mosquito bite, also sexually transmitted, and it can cause serious birth defects.
Prevention Bite avoidance, plus condoms or avoiding sexual contact, particularly in pregnancy. If you are pregnant or planning to be, the Government of Canada asks you to discuss the trip with a healthcare provider first and says you may choose to postpone. With Oropouche also on the list here, that conversation is worth having before anything is booked.
Chagas disease and leishmaniasis
Both are on CDC’s Panama list, and both on Canada’s. Chagas comes from triatomine bugs, which the Government of Canada notes are active at night; cutaneous and mucocutaneous leishmaniasis come from sand fly bites, most active between sunset and sunrise in rural and forested areas. Canada says the risk of each is generally low for most travellers.
Prevention Bite avoidance after dark, and a net if you are sleeping in poorly constructed or unscreened rural housing. There is no vaccine for either.
Leptospirosis and melioidosis
Both appear on CDC’s Panama list. Leptospirosis comes from water, mud or food contaminated with animal urine, including swimming or wading in fresh water and contact with floodwater; melioidosis from contact with contaminated fresh water, mud or soil, especially after heavy rain. Panama’s rainy season runs April to December and the Government of Canada says seasonal flooding can make roads impassable and damage bridges.
Prevention Avoid floodwater and muddy water after heavy rain, cover cuts and grazes before entering fresh water, and do not swallow river water. Bandage open wounds before contact with soil or water.
Hantavirus and tuberculosis
Both on CDC’s risk list for Panama — hantavirus from the urine, droppings or saliva of infected rodents, tuberculosis through the air from someone infectious. Neither changes what a typical trip needs, but the whole list belongs on the page rather than the convenient half of it.
Prevention Avoid rodents and places their waste builds up; avoid close contact with people who are unwell.
The sea, and diving
The Government of Canada says lifeguards do not usually supervise beaches, that tidal changes can cause powerful currents, that riptides are common and several drownings occur each year, and that rescue services may not be consistent with international standards. On diving specifically it says tour operators may not adhere to international standards, and asks you to choose a well-established and insured company and to check that your travel insurance covers the activity.
Prevention Ask locally which water is safe to swim and stay inside marked areas. Book diving with an established operator, and check that your policy names diving and medical evacuation before you pay for the course.
Food and water
The reason two of the vaccines on this page are the ones they are. The Government of Canada’s rule is boil it, cook it, peel it, or leave it, and it asks you not to swallow water when swimming, showering or bathing. Travellers’ diarrhoea is the most common illness travellers get anywhere.
Prevention Bottled or treated water, ice only from safe water, hot food served hot, fruit you peel yourself. Rehydration sachets in the bag — fluids are the treatment.
Roads
The Government of Canada says road conditions and road safety are poor throughout Panama, that drivers often drive dangerously, and that night construction on the Pan-American Highway is frequent and the highway is not well lit. It advises keeping windows closed and doors locked and being prepared for roadblocks. CDC names motor vehicle crashes among the main causes of death for travellers abroad.
Prevention No night driving on the Pan-American Highway if you can avoid it. Registered yellow taxis from a stand are described as generally safe; agree the fare first, because they are not metered.
