Pitt's Healthcare Advisory Group (HCAG) is charged with recommending University-wide health standards and guidelines that are needed to pursue the University's education and research mission to the fullest extent possible under pandemic conditions.  

The group’s role assures that Pitt is drawing on its world-renowned health sciences programs to guide decisions on the health and safety of students, faculty and staff alike.

“This group is composed of experts in health care and medicine, public health, occupational health and safety, infectious diseases and epidemiological modeling, emergency preparedness and the relevant legal regulations and compliance,” said HCAG Chair Anantha Shekhar, Pitt’s senior vice chancellor for the health sciences and John and Gertrude Petersen Dean of the School of Medicine.

“Its work will also be to continuously monitor the health status of the campus and align the University status to be well coordinated in our COVID-19 policies with the status of the city, county, state and beyond.”

Members of the HCAG—several of whom are both researchers and practitioners—bring their own specialized expertise as they develop detailed recommendations that are both sound and workable for the University community. They make recommendations for personal protective equipment and personal hygiene; shared spaces, distancing and density; virus monitoring, testing and tracing; safe mobility; and considerations for vulnerable populations.
