Hepatitis A is a contagious liver infection caused by the Hepatitis A virus. It is primarily spread through consuming contaminated food or water, often in areas with poor sanitation. Symptoms can include fatigue, nausea, abdominal pain, and jaundice, which is a yellowing of the skin and eyes. Most people recover fully within a few weeks, but it can be more severe in older adults or those with existing liver issues. Preventing Hepatitis A is possible through vaccination and practicing good hygiene, such as washing hands thoroughly after using the bathroom and before eating. Travelers to regions where the virus is common should consider getting vaccinated to protect themselves from infection.
