What are the symptoms of contracting hepatitis A?

Hepatitis A, fully termed Hepatitis A viral infection, presents with a variety of symptoms. In the early stages of infection, patients may have no obvious symptoms or may experience asymptomatic infection. However, as the disease progresses, most patients will develop acute onset symptoms, including systemic manifestations such as chills, fever (body temperature often between 38-39°C), general fatigue, dizziness, and headache. Additionally, gastrointestinal symptoms are common, including loss of appetite, nausea, vomiting, aversion to oily foods, and abdominal distension, primarily caused by liver damage due to the Hepatitis A virus. As the condition progresses, some patients may also develop jaundice,表现为 yellowing of the skin, urine, and sclera, which is one of the typical manifestations of Hepatitis A. Hepatitis A is highly contagious and mainly spreads via the fecal-oral route. Therefore, patients should seek timely medical attention and undergo isolation treatment after onset to prevent virus transmission to others. Moreover, treatment for Hepatitis A mainly involves rest and liver protection, and most patients can recover within a short period with active treatment. It should be noted that symptoms of Hepatitis A may vary due to individual differences. Therefore, patients should seek timely medical consultation upon experiencing related symptoms to establish a definitive diagnosis.
