The US Centers for Disease Control and Prevention is now asking most US schools to cancel football, wrestling, band and other school activities in an effort to slow the spread of the Covid-19 virus.

In the latest guidance recently issued by the CDC, they are advising schools to cancel high-risk sports and extracurricular activities for the time being. Those high-risk activities include: football, wrestling and band, and pointed to the recent spike in COVID-19 cases.

Many infectious disease experts are calling the guidance “unlikely, unreasonable and unrealistic.”

The CDC director defended the agency, saying in a statement it, “prioritized academics over athletics” and noted it can be incredibly effective when the guidance is followed.
