Penn State University sends students into lockdown after outbreak of potentially deadly infection on campus | 4 March 2025 | Students at a top US college are being told to isolate if they develop symptoms of chickenpox amid an outbreak on campus. Three cases of the highly transmissible infection have been detected at Penn State University. All the cases were at University Park, the main campus at the university which has about 42,000 students. It isn't clear whether the patients are staff or students, but university officials say they have found the "origin" of the outbreak and are now reaching out to close contacts. Students who were in the Mifflin Hall between February 17 and 24 and the Thomas building on February 20 between 1 and 3pm are being warned they may have been exposed to the virus. [Do not comply.]
