Health
Use normal food/water precautions: drink bottled, boiled, or treated water and be selective with raw foods. CDC flags dengue and other bite-borne risks; use repellent and cover up, especially in warmer/lowland areas. Malaria risk exists in some parts, mainly relevant to southern/border lowlands, so ask a travel clinic if your route includes them. Plan for altitude: many visitor routes are 2,000m+ and treks/passes can exceed 3,000m. Monsoon season can bring landslides; southern Bhutan is warmer and more humid.
Vaccinations
Consult a doctor or travel clinic at least 4 weeks before travel. Be current on routine vaccines, including MMR, polio, tetanus/diphtheria/pertussis, influenza, varicella, shingles as age-appropriate, plus COVID-19. CDC recommends hepatitis A and typhoid for many travelers, hepatitis B for unvaccinated travelers, Japanese encephalitis for longer rural/outdoor stays, and rabies pre-exposure discussion for animal/remote exposure risk. Yellow fever vaccine/certificate is not required or recommended for Bhutan by CDC.
eSIM / connectivity
Connectivity is practical in towns and tourist corridors. The main local carriers are Bhutan Telecom/B-Mobile and TashiCell. Bhutan Telecom lists eSIM and tourist eSIM packages, and TashiCell lists eSIM support plus tourist SIM packages. The tourism board says most hotels have Wi-Fi but recommends a guest SIM for more reliable mobile data; SIMs are available at Paro airport visitor information, carrier branches, and authorized town agents. Check handset eSIM compatibility before relying on it.
