As college students begin their fall semester, all 50 states have now reported positive cases of Covid-19 at colleges and universities.
This represents more than 45,000 cases of Covid-19 among students and staff at colleges and universities across the country.
Remember: This tally represents cases that CNN has reported so far. There are likely many others that have not been reported.
Additionally, many schools update their data every few days, or even once a week in some cases, so there can be a lag in data.
