Hepatitis A

Hepatitis A is a viral disease that is mainly transmitted through the ingestion of water or food contaminated with faecal matter. Poor hygiene therefore promotes the transmission of the disease.

After an incubation period of 3 to 5 weeks, this viral infection manifests itself with symptoms similar to those of influenza, accompanied by abdominal pain and sometimes jaundice.

The severity of the disease increases with age. In rare cases of complications, it can lead to death. The hepatitis A vaccine is very effective in protecting against the virus.

As the hepatitis A virus circulates more readily in countries with poor hygiene conditions, travellers to these countries are advised to get vaccinated. The vaccine must be administered at least 15 days before departure, with a booster 6 months later to extend protection to 10 years. Vaccination can be given from the age of one year.

Vaccination schedule

• Vaccination: 2 injections (15 to 30 days apart)
• Booster: 1 injection after 6 to 12 months
