The initial symptom that often occurs after exposure to Hepatitis A is a sudden onset of fever. This reflects the body's immune response to the Hepatitis A virus. After infection, the virus can take several weeks to manifest symptoms, but when symptoms do appear, fever is commonly one of the first signs, indicating that the body is fighting off the infection.

Fever, along with other early signs such as fatigue and malaise, helps in the identification of Hepatitis A. Understanding this initial symptom is crucial for early detection and preventive health measures, particularly in settings involving food handling and public health. Other symptoms, although they can also occur, typically follow after the fever and may include upset stomach, but fever is often the standout initial indicator of the infection.
