Hepatitis A outbreak from oysters and clams in Taiwan

There have been 30 cases of hepatitis A from October through November 2014. The source of the outbreak appears to be consumption of contaminated raw mollusks such as oysters and clams. Hepatitis A is concentrated by oysters, clams, and mussels that live and feed in contaminated seawater. Hepatitis A can be prevented through vaccination. When there is a risk of exposure to hepatitis A virus, travellers can reduce this risk by obtaining the vaccine prior to travelling and by exercising caution and avoiding consuming contaminated food and water.
