How can only one partner have molluscum?

It is unlikely that only one partner in a sexual relationship would have molluscum contagiosum. Molluscum contagiosum is a common skin infection caused by the molluscum contagiosum virus. It spreads through direct contact with an infected person's skin, or through contact with contaminated objects. If one partner has molluscum contagiosum, there is a high chance that the other partner will also get the infection if they come into close contact with them.

Molluscum contagiosum can sometimes clear up on its own, but it can take months or years. In some cases, treatment may be necessary to speed up the healing process or if the mollusca become infected.

It is important to practice safe sex and avoid contact with people who have molluscum contagiosum to reduce the risk of infection.
