CHICAGO (CBS) -- Advocate Health Care announced Wednesday that it has decided to close its clinics inside Illinois Walgreens drugstore locations. The 47 clinics will all close on Thursday, Feb. 6. The hospital group said the closures will allow it to expand its virtual services and in-person care at its primary and urgent care locations.

One or two medical office assistants work at each of the clinics, along with additional clinicians who support virtual care, and Advocate is working to find alternate roles for those employees,

Advocate Health Care, the largest provider of medical care in Chicago, is closing 47 clinics it has operated inside Walgreens stores for nearly a decade.
