MRSA is primarily given by two reasons!
1. Physical contact. (skin-to-skin contact with someone who has this disease)
2. Touching contaminated objects. (touching an object that has bacterial properties on its surface.)
It is only carried by 2 out of 100 people of our population (2%)
It is rare to get, but hospitals still see this disease.
To prevent from getting it, (this disease is common among teenagers and athletes) you should wash your hands, take showers, and bandage cuts and wounds often.
Actually, the correct answer is all three of them. A, B, C.
In all three, there have been reported cases when people who were using steroids did develop these symptoms. So saying, only one or two is likely a wrong answer. Because steroids are mostly (not all of course) composed of synthetic testosterone, the mentioned consequences are not that surprising.
