Which of the following is a common symptom of hepatitis A?

Fever is indeed a common symptom of hepatitis A. This viral infection of the liver often presents with systemic symptoms, including fever, which may occur as the body's immune system responds to the infection. Fever can be an early indicator of the body's attempt to fight off the virus.

In the context of hepatitis A, other typical symptoms may also include jaundice, fatigue, nausea, vomiting, and abdominal discomfort, particularly in the upper right quadrant where the liver is located. The presence of a fever signals that the body is actively dealing with the infection, making it an important symptom to recognize.

Other symptoms listed might not typically be related to hepatitis A. Severe abdominal cramps could indicate other gastrointestinal issues, chronic fatigue may be associated with various conditions beyond hepatitis A, and swollen lymph nodes are more closely linked to infections involving the lymphatic system or immune responses. Thus, while all symptoms can be significant in their own context, fever is prominently featured in cases of hepatitis A.
