Lafayette Journal & Courier WEST LAFAYETTE, Ind.— Purdue University announced Friday the return of a mask mandate starting Aug. 2 for all indoor spaces for students, employees and visitors, regardless of vaccination status. “We have a shared duty, part of the Protect Purdue Pledge, not only to preserve a manageable level of infection on campus so that we don’t have to suspend operations and interrupt our students’ education, but also to protect our surrounding community by doing everything we can to lessen the stress on local health care infrastructure, especially hospital capacity,” Dr. Esteban Ramirez, chief medical officer of the Protect Purdue Health Center, said in the release.
