Looking at 30 campuses across the nation with the highest amount of reported cases, experts saw that over half of the institutions had spikes -- at their peak -- which were well above 1,000 coronavirus cases per 100,000 people per week within the first two weeks of class.

In some colleges, one in five students had been infected with the virus by the end of the fall term. Four institutions had over 5,000 cases.
