Is Shingles contagious from human to human?

This can occur when the fluid from shingles blisters comes into contact with the skin of someone who has not had chickenpox or the vaccine.

If someone who has never had chickenpox or the vaccine is exposed to VZV through contact with shingles blisters, they may develop chickenpox. It is important to note that chickenpox is highly contagious, and the virus can spread easily from person to person through respiratory droplets or contact with blisters.

However, it is important to note that a person with shingles is not contagious unless they have open blisters. Once the blisters have crusted over, the risk of spreading the virus to others is greatly reduced.

It is still possible, however, for someone with shingles to spread the virus to others through respiratory secretions, such as coughing or sneezing.

To reduce the risk of spreading VZV, it is important for individuals with shingles to avoid close contact with people who have not had chickenpox or the vaccine, especially those with weakened immune systems, pregnant women, and infants.
