| Hepatitis A is spread through ingesting food or water contaminated by the feces of an infected person. People with HAV are infectious from the beginning of the incubation period (about a month before symptoms) until one week after they become jaundiced.
| | [[Category:Hepatology]] |
| Common ways of acquiring Hepatitis A are:
| | [[Category:Gastroenterology]] |
| * Direct Person-to-person transmission
| |
| ** Eating food made by someone who has HAV who did not properly wash their hands after using the bathroom.
| |
| ** Having anal or oral sex with someone who has HAV.
| |
| ** Not washing hands after changing a diaper (young children often are asymptomatic).
| |
| * Indirect transmission
| |
| ** Eating uncooked food that is HAV-contaminated. Cooked food can also cause Hepatitis if not heated to 185°F (85°C) for 1 minute after being contaminated with HAV.
| |
| ** Drinking contaminated water. This is a common route of infection in underdeveloped countries. Chlorinated water, such as tap water in developed countries, kills HAV.
| |
| If you have HAV or you live with someone who has HAV, to prevent spreading one with HAV should:
| |
| *Always wash hands thoroughly after going to the bathroom.
| |
| *Clean bathrooms often, paying attention to commonly-touched surfaces (toilet seats, faucet taps, etc.).
| |
| *Not prepare food for other people.
| |
| *Not share utensils.
| |
| *Not share any personal items that can spread HAV (toothbrushes, towels, etc.).
| |
| It is recommended that all people with Hepatitis A not work for 1 week after they become jaundiced to prevent spreading.
