As scientists study the burden of COVID-19 around the globe, it's pretty clear that despite some cases of serious illness, kids tend to get infected with the coronavirus less often and have milder symptoms compared to adults.

"It seems consistently, children do have lower rates of infection than adults," says Dr. Alison Tribble, a pediatric infectious disease specialist at C.S. Mott Children's Hospital at the University of Michigan.

How severe is the spread of COVID-19 in your community? If you're confused, you're not alone. Though state and local dashboards provide lots of numbers, from case counts to deaths, it's often unclear how to interpret them — and hard to compare them to other places.

Protests against the violent deaths of George Floyd, Breonna Taylor, Ahmaud Arbery and others are emboldening and expanding the movement to fight racism. But to make progress, many of us may need to adjust our thinking — and our actions. We talked to several African American and Hispanic psychologists and leaders for strategies to fight racism.

It has been months of quarantine for many of us. The urge to get out and enjoy the summer is real. But given that coronavirus cases continue to surge in many places, what's safe? We asked a panel of infectious disease and public health experts to rate the risk of summer activities, from backyard gatherings to a day at the pool to sharing a vacation house with another household.

How long can the new coronavirus live on a surface, like say, a door handle, after someone infected touches it with dirty fingers? A study out this week finds that the virus can survive on hard surfaces such as plastic and stainless steel for up to 72 hours and on cardboard for up to 24 hours.

Anxiety thrives on uncertainty.

And, as the coronavirus spreads, our unanswered questions can make us feel vulnerable or fearful. "Will it come to my community" or "Am I at risk?'

"We've got national anxiety at the moment, a kind of shared stress, and we are all in a state of extreme uncertainty," says Catherine Belling, an associate professor at Northwestern University, Feinberg School of Medicine, who studies the role of fear and anxiety in health care.

As the case count of coronavirus infections continues to rise in China, the number of reported infections among children is remarkably low.

"We're seeing [about] 75,000 total cases at this point, but the literature is only reporting about 100 or so pediatric cases," says Terri Lynn Stillwell, a pediatric infectious disease expert at Mott Children's Hospital at the University of Michigan.

Efforts to stem the tide of teen vaping seem to be a step behind the market. By the time Juul pulled most of its flavored pods from the market in October of 2019, many teens had already moved on to an array of newer, disposable vape products.

There's a seasonality to many viruses. Flu and cold viruses tend to peak in winter months, then die down with warmer weather.

Will the newly identified coronavirus and the disease it causes — COVID-19 — follow a similar pattern?

Before that question can be answer, let's consider how seasons and temperature influence the spread of viruses.
