How can I find out if I am infected with HEV?
Check with your physician if you suspect that you may have hepatitis of any form.

How can I prevent HEV infection?
Exercise caution when traveling to foreign coutries. Drink only safe water, that is water that is canned, boiled, or bottled. Avoid beverages made with ice. Boiling is the most effective method to ensure safe water, at high altitudes boil vigorously for a few minutes, then allow it to cool; do not add ice. Chemical disinfection can be accomplished through the use of either iodine or chlorine, iodine is the most effective disinfectant.
Avoid uncooked shellfish, and uncooked fruit/vegetables not peeled or prepared by yourself.
