The number of confirmed cases this year stood at 196 as of last Friday, said Dr. Steven Alles, Philadelphia’s director of disease control. Typically, the city sees two to six cases per year. Several more possible cases are being investigated.
There is not one particular hot spot of infection in Philly. “We are seeing cases presented from all over the city,” Alles told Metro. Most of the cases are in people who report using drugs or being homeless. But in a third of the infections, risk factors are unknown.
