As schools begin their fall semester, universities and colleges are struggling to contain coronavirus outbreaks with cases reported at campuses in all 50 states. There have been more than 40,000 cases of Covid-19 among students, faculty and staff at colleges and universities nationwide. The number represents cases that CNN has reported so far -- and is likely higher due to a lag from schools that update their data every few days. With social life trickling back to life on campuses, coronavirus outbreaks have hit places students congregate such as fraternities and sororities, where some have continued to gather despite remote learning.
