About staph infections.

I will like to know if someone can be affected with staph infection through sexual intercourse? Is it possible for that thing to happen or not? Even,
what is staph infection? What about VRE and MRSA, can this diseases too be transmitted through sexual intercourse?

These bacteria are all skin-contact bacteria. If they infect the genital area, it's possible to spread it through sexual intercourse. However, it's unlikely for each.

If you're involved with someone who's infected, avoid much of any contact. Also, speak to a doctor about the likelihood of getting infected. It could be more or less likely for your case than for other's cases.
