It is your choice if you want to talk to your current sexual partners about molluscum. Telling your partners lets them make informed choices. However, you may not want to or you may not feel safe telling your partners. You need to make the decision that is best for you.
Current partners can check themselves regularly for molluscum and visit their health care provider if they notice any symptoms. Once the molluscum bumps have disappeared, it’s less likely that the virus can be passed to partners.
