Causes of Hepatitis A
Hepatitis A is primarily caused by the ingestion of contaminated water or food. The most common source of the hepatitis A virus is consuming raw shellfish that have been exposed to polluted water or drinking from a contaminated stream. Another way to contract the virus is through sexual intercourse with an infected individual. Additionally, if an infected person prepares food for others, it can also lead to transmission. It is important to note that even individuals who do not display any symptoms can still transmit the virus.
Risk Factors for Hepatitis A
There are several factors that can elevate the risk of contracting hepatitis A. One of these is traveling to regions with inadequate sanitation or where hepatitis A is prevalent. Such travel increases the likelihood of coming into contact with contaminated water, thereby raising the chances of infection. Additionally, individuals who work or attend child care centers are also at a higher risk due to the increased potential for exposure to the virus. Moreover, those who are HIV positive or engage in intravenous drug use face an elevated risk of contracting hepatitis A.
