Health
Panama is tropical: plan for heat, humidity, strong sun, and heavy rain/possible flooding in the wet season. Use safe food and water habits, especially outside major hotels/cities. Mosquito-borne risks include dengue, Zika, chikungunya and malaria in some provinces; use bite prevention. Panama is mostly lowland, but Boquete/Volcan Baru hikes can be cool and high enough to pace exertion.
Vaccinations
Consult a doctor or travel clinic at least a month before travel. Be current on routine vaccines, including MMR, polio, Tdap, flu, shingles as applicable, plus COVID-19. CDC recommends hepatitis A for unvaccinated travelers, hepatitis B for many travelers, and typhoid for most travelers. Discuss malaria prevention for risk provinces and rabies pre-exposure only for higher-risk activities. Yellow fever vaccine is recommended for mainland areas east of the Canal Zone; not recommended for Panama City/Canal Zone/western areas. A yellow-fever certificate is not required for direct U.S. arrivals, but is required for travelers age 1+ arriving from countries with yellow-fever transmission risk.
eSIM / connectivity
Visitor connectivity is generally good in Panama City and main travel corridors, with weaker service in islands, jungle and remote coasts. Local mobile networks include Tigo and +Móvil/Cable & Wireless; prepaid physical SIMs are common. Travel eSIMs for Panama are widely sold by international eSIM providers and typically roam on local networks, but local walk-in prepaid eSIM availability is less consistently advertised, so confirm before arrival and keep a physical-SIM fallback.
