How can I prevent HEV infection?
Exercise caution when traveling to foreign countries. 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.
