Hepatitis causes inflammation of the liver. Hepatitis A and E are typically transmitted through contaminated food or water, whereas hepatitis B and C are through blood-to-blood contact.
Hepatitis A is usually mild, with symptoms lasting several weeks to several months. The best way to prevent it is by practising good hygiene while travelling.
Hepatitis B can be prevented by vaccinating against it and avoiding activities that risk exposure to blood from others, such as sharing needles for drugs or tattoos. Avoiding these activities also helps in the prevention of Hepatitis C.
