Chicago's lakefront convention center has prepared thousands of beds COVID-19 patients in case the demand on the city's hospitals requires a "relief valve," the city's mayor and officials leading the effort to convert McCormick Place into a temporary hospital said. State and city officials have said they hope the convention center will not be needed. It is designed to accept COVID-19 patients who donβt need the highest level of care that hospitals will focus on. Patients would be directly referred there from local hospitals.
