How long after shingles can not be transmitted

Herpes zoster is usually not contagious after 10-14 days, but it depends on the circumstances.

Herpes zoster is mainly caused by varicella-herpes zoster virus infection. It is typically manifested as painful blisters distributed along the nerve. The disease is mainly transmitted by contact with vesicular fluid. Because of the large number of virus particles in the vesicular fluid, it is usually not infectious before the vesicles appear. once the vesicles are broken, they lose their infectivity. once the vesicles are broken, they are highly infectious. The blister is usually in the first 10-14 days of scab, so about 10-14 days after the herpes zoster will not be infected. However, due to individual differences, if 10-14 days without scab blister, it still has a certain infectivity, need to pay more attention.
