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. People with certain allergic conditions and pregnant women may be encouraged to avoid the vaccine.
For those who are not vaccinated, the best ways to prevent hepatitis A infection are 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 people from getting sick when they have been exposed to the hepatitis A virus during an outbreak.
