Is herpes virus infection contagious?

Generally, herpes virus infections are contagious, with the highest transmissibility during symptomatic periods. The virus is less transmissible but still potentially contagious during asymptomatic latent phases. If concerned, it is recommended to seek medical consultation in advance. Detailed explanation is as follows:

When the herpes virus is in the active phase and symptoms such as skin or mucosal blisters and ulcers appear, large amounts of virus exist in the lesion secretions. At this time, the virus can be easily transmitted to others via direct contact with the lesion, sharing personal items such as towels, or close contact such as kissing and sexual activity. The transmissibility reaches its peak.

When the herpes virus is latent within the nerve ganglia and the patient has no obvious symptoms, viral replication remains at low levels. The transmissibility is lower compared to the symptomatic phase, but not completely absent. Some patients may experience asymptomatic viral shedding, meaning they do not display symptoms but are still capable of shedding the virus. Transmission through close contact is still possible, albeit at a lower probability.

In daily life, avoid sharing personal items with infected individuals and avoid close contact during active outbreaks. Keep the skin clean and dry to minimize opportunities for viral transmission. If infection is suspected, seek timely medical evaluation and, upon diagnosis, follow medical advice for preventive measures and treatment.
