Health
Use safe food and water: drink sealed/treated water, avoid ice of uncertain origin, and choose freshly cooked food. CDC notes active cholera transmission, malaria risk throughout Haiti, and mosquito-borne dengue/Zika; use repellent, covered clothing and screened/AC rooms. Heat, strong sun, flooding, freshwater exposure and disrupted health services can matter; high mountains are cooler but serious altitude illness is not a typical visitor issue.
Vaccinations
Consult a doctor or travel clinic at least a month before travel. Be current on routine vaccines, including MMR, polio, flu, varicella, Tdap, shingles as applicable, plus COVID-19. CDC recommends hepatitis A, hepatitis B for many travelers, typhoid for most travelers, malaria prevention medicine, and considering cholera or rabies vaccine based on risk. Yellow fever vaccine is not recommended for Haiti, but a certificate is required for travelers age 1+ arriving from countries with yellow-fever transmission risk.
eSIM / connectivity
Local mobile service is mainly Digicel Haiti and Natcom. Public local-carrier information shows physical SIM/mobile-internet options, but traveler eSIM is not as clearly or widely marketed as in some Caribbean destinations. If your phone needs eSIM, arrange an international travel eSIM that lists Haiti before arrival; otherwise plan for an unlocked phone and a local physical SIM where available. Coverage and reliability can vary outside main towns and during disruptions.
