The molluscum contagiosum virus, which causes MC, can be hard to avoid,
given that it is spread by skin-to-skin contact. The best tip is to avoid
touching or brushing up against a partner's MC lesions.
If you do get MC, you should avoid touching the lesion and then touching
another part of the body -- or another person -- without washing your
hands. This can help prevent the lesions from spreading.
Also, keeping the immune system healthy is the best way to prevent MC
lesions, even if you are exposed to the molluscum contagiosum virus. This
means keeping viral load low and T-cells high using anti-HIV drug treatment
and by adopting a healthy lifestyle.
