Hepatitis A is spread when the mouth comes in contact with objects, foods, or drinks that have been contaminated by the feces (or stool) of a hepatitis A infected person.
Other ways hepatitis A is transmitted include:
The best way to prevent contracting hepatitis A is to get vaccinated against it. According to CDC, the vaccine is safe and highly effective at preventing the infection. It is recommended to get vaccinated if you are traveling out of the country or are at a high risk for contracting the virus. Handwashing with soap and warm water after using the bathroom, changing a diaper, or before preparing food can also help prevent you from contracting hepatitis A.
If you have been diagnosed with hepatitis A, it is important to tell your partner and others you have recently come in direct contact with. This way they, too, can be tested and keep from spreading the virus if they have it.
No, if you have had hepatitis A in the past, your body has developed antibodies to the hepatitis A virus, so you cannot get it again. This same concept applies to the hepatitis A vaccine.
