Two new studies released on Tuesday take an in-depth look what may be driving the numbers up.
The study found that during that period, weekly Covid-19 cases among persons aged 18-22 years increased 55% nationally. Researchers found the greatest Increases in the Northeast at 144% and the Midwest at 123%.
“The observed increases in Covid-19 cases among persons aged 18-22 years could be driven by many factors, including changes in behavior or risk profiles resulting from multiple social, economic, and public policy changes during this period. Because approximately 45% of persons aged 18-22 years attend colleges and universities and 55% of those attending identified as White persons, it is likely that some of this increase is linked to resumption of in-person attendance at some colleges and universities,” the researchers wrote in the CDC’s weekly report on death and disease, the MMWR.
“Previous reports identified young adults as being less likely than other age groups to adhere to some Covid-19 prevention measures, which places them and their close contacts at higher risk for Covid-19,” they added.
“Their decision making … is more about ‘what’s in the moment, what am I missing out on, what is the thing that would make me happiest in this moment?'” Ben Locke, the senior director for Counseling & Psychological Services at Pennsylvania State University said.
That imbalance, he said, may cause this age group to make more risky decisions, like attending a party.

The university quickly determined the virus was spreading too fast and moved all classes online. It also asked students to move back home or off-campus.
By August 25, 670 cases of Covid-19 had been confirmed, almost all of them in people under the age of 22.
The largest cluster was at an off-campus apartment complex affiliated with the university.
“The rapid increase in cases within two weeks of opening campus suggests that robust measures are needed to reduce transmission at institutes of higher education, including efforts to increase consistent use of masks, reduce the density of on-campus housing, increase testing for SARS-CoV-2, and discourage student gatherings,” the researchers wrote.
