Hello. Thank you for writing to usShingles
is due to reactivation of varicella
zoster virus/ VZV. This is teh same virus that causes chicken pox
The virus once acquired remains dormant inside body and may reactivate at times to produce shingles.
Shingles usually presents as grouped, discrete, fluid filler vesicles.
There is associated pain which can vary in intensity from mild to severe and this may last even after the lesions of shingles have resolved.
Treatment is with Oral antivirals e.g acyclovir
or valacyclovir for a week.
usually heals in 7 or 10 days on oral antivirals.
Shingles is contagious and the virus can spread by direct contact with the infected fluids from the lesions.
The infectivity however only last as long as the lesions are moist and becomes zero when the lesions dry up.
It is better not to share any towels, clothing, bedsheets of shingles patients till the lesions resolve.
Keeping the lesions covered also decreases the infectivity.
