Mongolia Travel Health Advice
No particular immunisations are required for travel to Mongolia, although standard vaccinations like hepatitis A and B, typhoid, and rabies are recommended. Vaccines for meningococcal disease are recommended for extended stay or prolonged contact with the local population. Traveller's diarrhea is the most common complaint, and altitude sickness may be experienced in the Altai, Hangayn, or Khangai Mountains. There have been no infectious outbreaks reported in the last few years.
It is advisable to only drink boiled or filtered water in Mongolia, and avoid raw and unpeeled fruits and vegetables. In addition, long clothes will prevent bug bites and related illnesses. Medical facilities in Mongolia are limited, so travel insurance with evacuation provisions is recommended. There are some private hospitals suitable for foreigners in Ulaanbaatar, and be prepared to pay up front and claim back later. Some Western medications are not available, so it's advised to pack important medication, accompanied by a doctor's note explaining the need and purpose.
