Herpes virus infection can cause fever?

　　In general, whether herpes virus infection causes fever depends on the type of infection and the individual's immune status. If discomfort symptoms occur, it is recommended to seek timely medical consultation and treatment at a regular hospital. Detailed analysis is as follows:

　　If it is a primary herpes virus infection and the individual's immune status is weak, the body's immune system usually mounts a strong response after infection, often accompanied by fever symptoms with body temperature possibly rising above 38℃. Other symptoms may include fatigue, muscle pain, and skin blisters at the infection site. Fever typically lasts for 3-5 days and gradually subsides as the condition is controlled.

　　If it is a recurrent herpes virus infection, or if the individual has a strong immune system, fever symptoms usually do not occur. In such cases, the virus only activates in local nerve ganglia, mainly manifesting as localized skin blisters, pain, or itching. The symptoms are milder compared to primary infection, and the body's immune system can usually control viral replication quickly, without requiring a strong immune response such as fever.

　　When fever occurs, attention should be paid to rest, drinking plenty of warm water, and avoiding excessive fatigue. If body temperature exceeds 38.5℃, antipyretic medications may be used under a doctor's guidance. The affected area should be kept clean and dry, and scratching should be avoided to prevent secondary infection. If fever persists or symptoms worsen, timely medical consultation is necessary to determine the condition and follow medical advice for treatment.
