The causative agent of Chickenpox and Shingles

People get shingles when the varicella zoster virus, which causes chickenpox, reactivates in their bodies after they have already had chickenpox. Shingles is caused by varicella zoster virus (VZV), the same virus that causes chickenpox. After a person recovers from chickenpox, the virus stays dormant (inactive) in their body. The virus can reactivate later, causing shingles. Most people who develop shingles have only one episode during their lifetime. However, you can have shingles more than once. If you have shingles, direct contact with the fluid from your rash blisters can spread VZV to people who have never had chickenpox or never received the chickenpox vaccine. If they get infected, they will develop chickenpox, not shingles. They could then develop shingles later in life. The risk of spreading VZV to others is low if you cover the shingles rash. People with shingles cannot spread the virus before their rash blisters appear or after the rash crusts. People with chickenpox are more likely to spread VZV than people with shingles. #shingles #chikenpox #varicellaZosterVirus #VIRUS #Genetics #virology
