Who should receive hepatitis A vaccine?
Persons who work in or travel to areas where hepatitis A is common. (first dose should be given at least 4 weeks before travel)
Children in states and countries with constant increased rates of hepatitis A. County and state health departments can tell you whether your areas have these higher hepatitis A rates.
Men who have sex with men
Persons who use street drugs
Persons with clotting factor disorders, such as hemophilia
Persons who work with HAV-infected animals or work with HAV in a research setting (hepatitis A vaccine is not generally recommended for health care workers).
Can you get hepatitis A from food or water?
|
In addition to getting hepatitis A directly from infected people, you can get hepatitis A by: swallowing contaminated water or ice eating raw shellfish harvested from sewage-contaminated water eating fruits, vegetables, or other food that may have become contaminated during handling |
Can HAV be killed?
The virus is killed by boiling at 85 degrees C (185 degrees F) for 1 minute. However, the disease can still be spread by cooked foods if they are contaminated after cooking. Adequate chlorination of water, as recommended in the United States, kills HAV.
