PHILADELPHIA (CBS) - Customers of Monarch Med Spa, which offers cosmetic surgery procedures, are being warned of possible exposure to Group A Streptococcus.

Health officials are warning people in Delaware and Pennsylvania after learning of infections among several customers. Officials say of those infected, two people from Delaware may have contracted the illness from out-of-state locations.

Monarch Med Spa has facilities in Greenville, Delaware; King of Prussia, Philadelphia and Harrisburg, Pennsylvania; and Timonium, Maryland, which was recently shut down according to authorities after a woman reportedly died from the infection.

Symptoms include fever, infection or prolonged redness of the wound site after a procedure. Anyone who visited Monarch Med Spa and has these symptoms should contact their health care provider or the Delaware Division of Public Health at 302-242-8352.
