It is more likely a reactivation of the virus in your body. It is mostly harmless. Visit this site for more information on this issue: https://www.cdc.gov/poxvirus/molluscum-contagiosum/index.html Wish you good health!

You were probably in contact with someone that transmitted a different strain of the virus to you. Or it could be something else that resembles molluscum in appearance. You should see a dermatologist to get an accurate diagnosis and proper treatment.
