PITTSBURGH (AP) — A children’s hospital in Pittsburgh says a dozen people _ including six babies _ are being treated for the antibiotic-resistant staph infection known as MRSA. The University of Pittsburgh Medical Center says the young patients are in the Children’s Hospital neonatal intensive care unit. Staff with potential symptoms came forward and six were confirmed to have the infection. UPMC says all NICU patients have been tested and one patient may have symptoms of illness.
