Millions are asking for clear, comprehensive information and guidelines regarding the novel coronavirus. Unfortunately, the U.S. public hasn’t received factual information or future direction from the federal government. Instead, the government has underreported cases and local transmission rates due to a lack of testing kits.

But during a crisis, leadership can come from unexpected places.

As he suspended all NBA games, commissioner Adam Silver delivered a powerful message to the public that the outbreak must be taken seriously. With that single announcement, Silver enforced more effective public health policy than the White House has during this pandemic. Shortly thereafter, all other major sports leagues followed his lead; the NBA’s decisive action helped the dominoes fall.

Last January, NFL running back Marshawn Lynch delivered solid advice for his younger colleagues in a post-game interview: take care of your bodies, your mentals, and your chicken (that is, your money). Fortuitously, this is also applicable for everyone during COVID-19.

As an assistant professor of biology at The Pennsylvania State University, I study infectious disease risks and preventative solutions. I know the only way to stop this outbreak and prevent severe cases is to reduce transmission. Without all of us changing our behavior, those who are more likely to experience severe outcomes will have negative health outcomes.

While the elderly and people with respiratory conditions are at highest risk, severe cases have also been reported in young, otherwise healthy people. Without behavioral interventions, so many patients will require hospitalization, they will exceed the capacity of the U.S. health care system. This will cause preventable deaths.

Reducing overall transmission will protect the most vulnerable members of our communities and keep the health care system functioning. You are no longer making decisions for only yourself, you have to constantly consider how your personal behavior is going to impact everyone around you and everyone around them.

You need space, but you also need connection

So far, no pharmaceutical interventions, such as vaccines and antiviral drugs, exist. At the moment, we must rely on basic public health measures: wash your hands frequently, don’t touch your face, use hand sanitizer, and limit your exposure to others. It may sound simplistic, but those things are enormously helpful. Non-pharmaceutical interventions are extremely effective against infectious diseases; all Ebola epidemics prior to 2014 are just one example.
