Question: How Long Can the Hepatitis Virus Live Outside the Body?
The viruses that cause hepatitis can live outside the body and be infectious for certain periods of time. A good rule of thumb is that wet material is infectious and dried material is much less infectious. Here's a closer look at each one of the five hepatitis viruses:
The hepatitis A virus, or HAV, is relatively hardy. In good conditions, it can survive outside the body for months. HAV can survive certain acids and some heat. For a period of time and under certain conditions, HAV can survive in sea water, dried feces and live oysters.
The hepatitis B virus, or HBV, can still be infectious for up to a week outside the body.
The hepatitis C virus, or HCV, can live outside the body for up to 4 days. However, many experts think it usually survives up to 16 hours at room temperature.
This virus needs help from the hepatitis B virus to be infectious, so it only infects someone with hepatitis B.
This virus is spread similar to the hepatitis A virus and causes acute disease similar to the others.
