Is the herpes zoster virus contagious?
Under normal circumstances, the herpes zoster virus is contagious. If discomfort symptoms occur, it is recommended to seek timely medical treatment at a regular hospital. Detailed analysis is as follows:
The herpes zoster virus is contagious and mainly spreads through direct contact with the skin blister fluid of infected individuals, although it can also spread via respiratory droplets. The contagiousness is particularly strong before the blisters have crusted over. Individuals who have never been infected with the varicella-zoster virus may develop chickenpox after exposure, while in those previously infected, the virus remains dormant in the sensory ganglia and may reactivate when immunity decreases, causing herpes zoster. Most adults have been infected with the varicella-zoster virus; therefore, people around patients with herpes zoster should take precautions and avoid close contact.
Patients should maintain clean skin and avoid allowing blister fluids to come into contact with others after rupture. Before the blisters have crusted over, going outdoors should be minimized, especially avoiding contact with infants, pregnant women, elderly individuals, and those with weakened immune systems. Healthy individuals who have not received the chickenpox vaccine may consider vaccination after consulting a physician to reduce the risk of infection. Maintaining regular作息 patterns and a balanced diet in daily life can enhance personal immunity and reduce the likelihood of viral reactivation or infection.
