Hepatitis A is a highly resistant virus transmitted by close contact or food and water. Vaccination and hygiene are the main means to prevent the disease.
Endemicity of Hepatitis A is variable among regions. The virus highly circulates around the world and vaccination is recommended for at-risk populations.
People from low HAV endemicity areas travelling to high HAV endemicity areas are potentially at-risk if not vaccinated against the disease.
Safe and effective hepatitis A vaccines have been available for more than 20 years. Hepatitis A vaccines contain antigens derived from hepatitis A virus strains grown in cell culture.
Salmonella Typhi can survive several days in water and for months in contaminated food such as eggs or frozen oysters.
Typhoid fever is widespread throughout the world. In 2017, 10.9 million cases worldwide led to 116,800 deaths, and billions of people are likely to be exposed to it.
The risk for travellers varies according to the geographical area, the highest rates occurring for those who visit South Asia as well as West and Central Africa.
There are 3 types of Typhoid Vaccine available: Live attenuated Ty21a vaccine, Vi polysaccharide vaccine and Vi polysaccharide conjugate vaccine, the last being only available for populations living in countries of very high endemicity.
Typhoid fever is a vaccine-preventable disease. Vaccination against typhoid fever is recommended by the World Health Organisation (WHO) for travelers going to typhoid-endemic areas.Download the infographic
Since the beginning of time, the disease has terrified entire civilizations since it transpired that the bite of a rabid animal almost always resulted in death.
Rabies disease is fatal once symptoms appear, but it is preventable if pre- and post-exposure prophylaxis procedures are carried out properly.
Rabies is usually transmitted to humans though saliva, by a bite or scratch from an infected mammal, a dog in 99% of cases.
Today rabies is still endemic in more than 150 countries, killing every year 59,000 people. 95% of the victims are located in Asia and Africa, and 40% are children.
Rabies is a vaccine-preventable disease. Vaccination might be indicated for outdoor travellers to remote areas with a high rabies exposure risk and limited local access to rabies vaccines.Download the infographic
After an incubation period of 3 to 6 days, patients infected experience abrupt onset of symptoms.
Yellow fever was brought to North America and Europe through its ports from the 17th to 19th century.
In West Africa, an unvaccinated traveller visiting an endemic area for a 2-week stay would be at a risk of 5 in 10 000 of catching the Yellow fever virus.
The Yellow fever vaccine is manufactured by several suppliers, four of which are WHO-prequalified. All are live attenuated viral vaccines from the 17D lineage, cultured in embryonated eggs.
Occasionally travellers who visit yellow fever endemic countries may bring the disease to countries free from yellow fever. To prevent importation of the disease, many countries require proof of vaccination against yellow fever.Download the infographic
Japanese Encephalitis is an acute inflammatory disease of the central nervous system in humans transmitted by culex mosquitoes and that can cause death
