Pennsylvania Health Department workers visited Monarch Med Spa in King of Prussia on Monday, the company said, but have not issued findings from the visit.
Monarch's locations there and in Philadelphia, Harrisburg, and Greenville, Del., are being investigated after Maryland last week closed its other facility, in Timonium, north of Baltimore. The closure followed invasive group A streptococcus (GAS) infections in three women, one of them fatal, who underwent liposuction there.
A Delaware Health Division spokeswoman said Monday that it had confirmed invasive GAS in one resident, no longer hospitalized, who had "a surgical" procedure at a Monarch location in Pennsylvania. The location was not released, but only King of Prussia performs more invasive procedures like liposuction.
