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.

Chikungunya Virus, Dengue Fever, Zika Virus

Chikungunya Virus, Dengue Fever and Zika Virus are viral illnesses borne by mosquitoes. The risk is present in many countries in the tropics. There is no vaccine to prevent these illnesses (Dengue fever vaccine is currently available in a few countries). Please discuss your travel plans with a doctor who can assess your risk based on your itinerary.

Hepatitis A

This is a viral disease of the liver which is transmitted through eating contaminated food or drinking contaminated water.

Hepatitis B

This is a viral disease of the liver that is transmitted via blood, blood products or bodily fluids and is vaccine preventable.

Influenza

Travelers go through crowded venues like airports, or on commuter transport. Influenza is the most common vaccine to prevent travel related illness. Vaccination against influenza is generally highly recommended.

Japanese Encephalitis

JE is a mosquito borne viral disease prevalent in rural areas of Asia that can lead to serious brain infection in humans. Risk is greatest during the monsoon months however the risk is generally very low for most travelers. Vaccines are available if the exposure risk is deemed to be high.

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 doctor, taking into consideration the relative malaria risk of areas on the traveller’s itinerary as well as any potential side effects.

Measles, Mumps, Rubella (MMR)

Vaccination is recommended for travelers born after 1966 who cannot confirm that they have received two doses of measles containing vaccine. Since 1990, this may have been the combination vaccine MMR (measles, mumps and rubella).

Meningococcal Disease

Meningococcal disease is a very serious bacterial infection which is often life-threatening. It may manifest as meningitis (inflammation of the lining of the brain)and/or septicaemia (blood poisoning).

Poliomyelitis

All travelers should be up to date with vaccination against polio. Poliomyelitis is a viral infection that can lead to paralysis and sometimes death. For those who have completed childhood immunisation, a single booster dose of polio vaccine as an adult will generally provide long-term protection.

Rabies

Rabies is a deadly viral infection of the brain. Risk increases with extended travel and the likelihood of animal contact.

Schistosomiasis

This disease is caused by a free swimming parasite released by fresh water snails. The disease can develop after swimming or bathing in water from rivers, streams and lakes.

Tetanus, Pertussis, Diphtheria

Tetanus is caused by a toxin released by common dust or soil bacteria which enters the body through a wound. Diphtheria is a bacterial infection of the throat and less frequently, the skin. Pertussis or whooping cough (known as the 100 day cough in Chinese) is a highly infectious respiratory infection responsible for over 300,000 deaths annually, mainly in children. These three illnesses are preventable and covered in the same vaccine.

Traveler’s Diarrhoea

Up to 40% of tourists may develop three or more loose bowel motions a day within the first week of travel. A variety of germs can be responsible for this infection and a travelers may choose to pack products such as Gastro-Stop to remedy the problem quickly.

Typhoid

Typhoid fever is caused by bacteria found in contaminated food and water. It is endemic in the developing world and vaccination is recommended for travelers to areas where environmental sanitation and personal hygiene may be poor.

Yellow Fever

This viral illness is spread by mosquitoes in and around forest areas and has a mortality rate of up to 50%. A vaccine is available for those over nine months of age. An international certificate of vaccination is often required for travelers returning to their home country from destinations where yellow fever is known to be present.
