Prevention

The best way to prevent hepatitis A is to be vaccinated. The vaccine has been available since the 1990s, and health experts recommend it for travelers going to Africa, Asia, Central and South America, or Eastern Europe. Healthcare providers may encourage patients with certain allergic conditions and pregnant women to avoid the vaccine.

If you aren't vaccinated, the best ways to prevent hepatitis A infection are by practicing good sanitation and hygiene and avoiding contaminated food and water, especially when traveling in countries where hepatitis A is common.

Taking immunoglobulin (a protein that fights infection) will help keep you from getting sick if you have been exposed to hepatitis A virus during an outbreak.
