Methicillin-resistant Staphylococcus aureus, or MRSA, is a type of drug-resistant bacteria that infects the skin, heart or central nervous system of hospitalized patients. In recent years, though, a more virulent strain has emerged that can infect healthy people. Staphylococcus outbreaks among athletes are becoming increasingly common, due to the players' frequent direct person-to-person contact.
Researchers found that 10 percent of players on a Connecticut college football team had MRSA skin infections, for which two were hospitalized. Cornerbacks and wide receivers, who frequently come into direct contact with other players, accounted for the most MRSA cases. Even minor damage to the skin greatly increased players' risk of contracting MRSA. The athletes who practiced cosmetic body shaving had a 43 percent risk of infection. Those who sustained turf burns during play were seven times more likely than their teammates to contract MRSA. Players sharing inadequately disinfected whirlpools may have also contributed to the MRSA spread.
The outbreak was stemmed, in part, by the proper disinfection of whirlpools and the installation of antibacterial soap dispensers to the athletes' showers. However, there are other ways of helping to control MRSA, according to Dr. Elizabeth Begier, lead author of the study. "You may not notice it, but when you are shaving, you create micro-abrasions," said Dr. Begier. "It's not intuitive to the young men involved in this... even if you don't see it, there are small breaks there." The researchers recommend discontinuing the practice of body shaving to decrease the risk of infection.
Turf burns may not be entirely preventable, but athletes should take note when they happen, said Dr. Begier. "When they have these large abrasions during game play they should stop and have them cleaned and covered" to reduce the risk of contracting MRSA or transmitting it to other players, she said.
