About hepatitis

Hepatitis means inflammation of the liver. Common causes of hepatitis include: viruses, bacterial infections, toxins, certain drugs, excessive alcohol use and other diseases.

Hepatitis A

Almost all hepatitis A are spread by the faecal-oral route (ingestion of faecal matter) either by food and water contaminated by infected faeces or certain sexual practices.

Hepatitis B

The infection occurs through the exchange of infected blood or body fluid from an infected person. This usually occurs through sexual contact or on using unsterilised needles or during exposure at work such as in a healthcare setting.

Hepatitis C

Like hepatitis B, this virus spreads through exposure to infected blood and less commonly through sexual contact.

Hepatitis D

The infection occurs only in people infected with hepatitis B and spreads in the same way as hepatitis B.

Hepatitis E

This virus mainly spreads through faecal-oral mode through faecal contamination of drinking water. Sometimes it spreads via undercooked/raw meat or shellfish.



Hepatitis can affect business travellers. Like everyone, they should take steps to prevent infection. There are vaccines to protect people from hepatitis A and B. Hepatitis E vaccine is available in China only
