Three high school athletes in Worcester have been diagnosed with MRSA, a type of staph infection that is resistant to common antibiotics.
The city has issued a health alert but say there is no major risk to the public.
Two students at South High Community School and one from Worcester Technical High School became ill this week. Officials say they are receiving treatment and continue to attend classes.
All three students play contact sports and apparently developed the infection through cuts on their skin. Doctors say the disease can be transmitted through skin-to-skin contact.
School officials are cleaning and disinfecting locker rooms and other parts of the schools.
Bathrooms, locker rooms and other parts of Westford's high school were disinfected last month after four students were diagnosed with MRSA.
