Hepatitis A causes

Causes
Hepatitis virus (HAV) is a non-enveloped ssRNA virus with a single serovar.

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. Common ways of acquiring Hepatitis A are: If you have HAV or you live with someone who has HAV, to prevent spreading one with HAV should: It is recommended that all people with Hepatitis A not work for 1 week after they become jaundiced to prevent spreading.
 * 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.
 * 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.).
