How likely are you to get chickenpox from someone with shingles if have not had chickenpox?

It is important to note that if you have not had chickenpox, it is not typically possible to contract it from someone with shingles. Shingles is a reactivation of the chickenpox virus in an individual who has had chickenpox in the past. Chickenpox is the primary infection with the virus, while shingles is a result of the virus being reactivated.

However, there are certain cases where someone who has not had chickenpox may be at risk of contracting the virus from an individual with shingles. This is more common in individuals with weakened immune systems or those who have never been vaccinated against chickenpox. In these situations, it is possible, although uncommon, for someone who has not had chickenpox to develop the condition after coming into close contact with someone who has shingles.

Chickenpox is generally considered more transmissible than shingles. If someone who has not had chickenpox comes into contact with someone who has chickenpox, the chances of contracting the virus are higher compared to contact with someone with shingles.

To prevent chickenpox, vaccination is recommended for those who have not been previously infected. The varicella vaccine is highly effective in preventing both chickenpox and shingles, reducing the risk of developing these conditions.
