- Confirm primary courses and boosters are up to date as recommended for life in Britain - including for example, seasonal flu vaccine (if indicated), MMR, vaccines required for occupational risk of exposure, lifestyle risks and underlying medical conditions.
- Courses or boosters usually advised: Diphtheria; Hepatitis A; Tetanus.
- Other vaccines to consider: Hepatitis B; Typhoid.
- Selectively advised vaccines - only for those individuals at highest risk: Cholera; Japanese Encephalitis; Rabies.
No yellow fever vaccination certificate required for this country.
Notes on the diseases mentioned above
spread through consumption of contaminated water and food. It would be unusual for travellers to contract cholera if they take basic precautions with food and water and maintain a good standard of hygiene.
Risk is higher during floods and after natural disasters, in areas with very poor sanitation and lack of clean drinking water.
Risk is highest for humanitarian aid workers; those working in refugee camps or slums; those caring for people with cholera.
- Diphtheria:  spread person to person through respiratory droplets. Risk is higher if mixing with locals in poor, overcrowded living conditions.
spread through consuming contaminated food and water or person to person through the faecal-oral route.
Risk is higher where personal hygiene and sanitation is poor.
Risk is highest for those with underlying medical conditions where there is increased risk of severe disease e.g. chronic liver/kidney disease; haemophiliacs; men who have sex with men; people who inject drugs.
spread through infected blood and blood products, contaminated needles and medical instruments and sexual intercourse.
Risk is higher for long stays, frequent travel and for children (exposed through cuts and scratches), those who may require medical treatment during travel.
Risk is highest for those with underlying medical conditions where there is increased risk of severe disease e.g. chronic liver/kidney disease; haemophiliacs; men who have sex with men; people who change partners frequently; people who inject drugs.
- Japanese Encephalitis:  spread through the bite of an infected mosquito. This mosquito breeds in rice paddies and mainly bites between dusk and dawn. Risk is highest for long stay travellers to rural areas, particularly if unable to avoid mosquito bites.
- Rabies:  spread through the saliva of infected animals (especially dogs, cats, bats and monkeys), usually through a bite, scratch or lick to broken skin. Risk is higher for those working or living in remote or rural areas (with no easy access to medical facilities), longer stay travellers, those planning on undertaking activities such as trekking, cycling or running in a 'high risk' country, those working with, or regularly handling animals or bats, as part of their job, and children. Even after receiving pre-travel rabies vaccine, urgent medical advice should be sought after any animal or bat bite.
- Tetanus:  spread through contamination of cuts, burns and wounds with tetanus spores. Spores are found in soil worldwide. A total of 5 doses of tetanus vaccine are recommended for life in the UK. Boosters are usually recommended in a country or situation where the correct treatment of an injury may not be readily available.
- Typhoid:  spread mainly through consumption of contaminated food and drink. Risk is higher where access to adequate sanitation and safe water is limited.
Malaria is a serious and sometimes fatal disease transmitted by mosquitoes.You cannot be vaccinated against malaria.
Malaria precautionsMalaria Map
- Malaria risk is low throughout the year in all areas.
- Malaria precautions are essential. Avoid mosquito bites by covering up with clothing such as long sleeves and long trousers especially after sunset, using insect repellents on exposed skin and, when necessary, sleeping under a mosquito net.
- Check with your doctor or nurse about suitable antimalarial tablets.
- See malaria map – additional information can be found by clicking on the Regional Information icon below the map.
- Low to no risk areas: antimalarial tablets are not normally advised.
- If you have been travelling in a malarious area and develop a fever seek medical attention promptly. Remember malaria can develop even up to one year after exposure.
