Major Travel Health Issues & Considerations for Nepal, Tibet & Bhutan 

Hepatitis A: This is a viral disease of the liver which is transmitted through eating contaminated food or drinking contaminated water. It is the most common vaccine-preventable disease that occurs in travelers to less developed areas of the world. It is strongly recommended for travel to Nepal.

Hepatitis B: This is a viral disease of the liver that is transmitted via blood, blood products or bodily fluids. It is vaccine preventable. Hepatitis B immunization is now part of the childhood immunization schedule. Many adult travelers have missed this very important immunization & travel may be a good reason for vaccination.

Typhoid: Typhoid Fever is caused by some bacteria found in contaminated food & water. It is endemic in the developing world & vaccination is recommended for travelers to areas where environmental sanitation & personal hygiene may be poor. The adventurous eater venturing off the beaten, path should certainly consider vaccination.

Tetanus, Pertussis & Diphtheria: Tetanus is caused by a toxin released by a common dust or soil bacteria, which enters the body through a wound. Diphtheria is a bacterial infection of the throat & occasionally of the skin. It is found worldwide & is transmitted from person-to-person by coughing & sneezing.

Chickenpox: This very common infectious disease can now be prevented through immunization. Many people miss the disease in childhood only to have a significant illness as an adult. Travel puts one at higher exposure & if one cannot elicit a history of having had the illness a test can show whether at risk.

Influenza : Individuals intending to travel out of an Australian winter might consider the current flu vaccine at the beginning of the season. Exposure to illness in airports & commuter transport is common & exposure may ruin a much-needed break. In fact, influenza is likely to be the most common vaccine-preventable disease faced by travelers.

Poliomyelitis: All travelers to Nepal should be up to date with vaccination against polio. Poliomyelitis is a viral infection that can lead to paralysis & sometimes death. Transmission is by fecal contamination of food, usually by unhygienic food handlers or flies, or directly from infected nasal secretions. Polio is no longer endemic in Nepal, but imported cases from India do occur. Although most Australians & New Zealanders will have been immunized in childhood, it is important to note that efficacy wanes after 10 years & a booster dose is recommended if traveling to a country where the disease can still be found.

Malaria: Malaria is transmitted by a night-biting mosquito. The decision to use or not use anti-malarial drugs should be made after consultation with a travel health specialist, taking into consideration the relative malaria risk of areas on the traveler’s itinerary as well as potential side effects & cost of available drugs. Insect avoidance measures should be followed throughout the trip. Upon return, any flu-like illnesses should be investigated by a travel health specialist. See below.

Meningitis: Meningitis is an inflammation of the membrane overlying the brain. It can be caused by bacteria, a virus or a fungus. Bacterial meningitis is the form of most concern to travelers. It is a serious disease & can rapidly become life-threatening. It is transmitted from person-to-person through close contact (i.e. droplet infection the same way you catch a cold). Vaccination might be considered for those backpacking off the beaten path or those working in health areas where crowded conditions occur. The tea house accommodation in most of the treks in Nepal is conducive to the spread of meningitis & epidemics occur sporadically.

Japanese Encephalitis (JE): JE is a mosquito-borne viral disease prevalent in rural areas of Asia that can lead to serious brain infection in humans. The risk is usually greatest during the monsoon months. A vaccine is available & is particularly recommended for adults & children over 12 months of age who will be spending a month or more in rice growing areas of countries at risk (or who repeatedly visit such areas). It is also recommended for people traveling to an area where an outbreak is known to be occurring. Insect avoidance should be considered the primary means of defense. The risk is higher in the southern lowlands bordering India (Terai).

Rabies: Rabies is a deadly viral infection of the brain transmitted to humans. The disease itself is rare in travelers, but the risk increases with extended travel & the likelihood of animal contact. The best way to avoid rabies is to avoid all contact with animals. Dogs are the main carriers; however, monkeys, bats, cats & other animals may also transmit the disease. Pre-exposure vaccination is recommended for extended travel & those who work with or are likely to come in contact with animals.

Cholera: Cholera is a severe, infectious diarrhoeal disease caused by bacteria. It is common in developing countries & is associated with conditions of poverty & poor sanitation. Cholera causes severe & rapid dehydration. Travelers who follow the rules of eating & drinking safely will minimize their risk. There is also a new oral vaccine available for cholera which may be recommended under certain circumstances.

Diarrhea : Up to 20% of tourists may develop 2 or more loose bowel motions a day within the first week of travel. A variety of germs can be responsible for this infection & a Travellers Medical Kit containing appropriate therapy can rapidly improve the symptoms. It is also important to follow the rules of healthy eating & drinking to minimize risks. The new oral cholera vaccine has been shown to provide limited protection against some forms of diarrhea.
