PORTLAND, Maine — Officials in Portland, Maine, say two children who attended a summer day camp in a community center have been diagnosed with an antibiotic-resistant skin infection.

The infection is commonly called MRSA, which stands for methicillin-resistant Staphylococcus aureus. Portland spokeswoman Jessica Grondin says one child was hospitalized and has since been released.

The Portland Press Herald (http://bit.ly/2vtyNOe ) reports the children attended a day camp at Riverton Community Center in the city. It’s not known exactly where they contracted the infection.

Custodial staff spent Monday night and all day Tuesday cleaning and disinfecting common areas the children may have touched. Grondin says danger to the public is minimal.

The Maine Center for Disease Control & Prevention has been notified about the incident. MRSA infections can spread into more serious illnesses if untreated.
