It has been around two months of quarantine for many of us. The urge to get out and enjoy the summer is real. But 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.

In an era of online shopping and global shipping, some NPR listeners have written to us with this question: Am I at risk of catching the new coronavirus from a package I receive from China?

Almost certainly no, according to the Centers for Disease Control and Prevention.

"Because of poor survivability of these coronaviruses on surfaces, there is likely very low risk of spread from products or packaging that are shipped over a period of days or weeks at ambient temperatures," the CDC concludes in its Q&A.

If you live in the U.S., your risk of contracting the new strain of coronavirus identified in China is exceedingly low.

Memphis Meats, a Berkeley, Calif.-based startup, says it's one step closer to bringing cell-based meat to consumers' mouths.

The company plans to build a pilot production facility with funds raised from high-profile investors including Bill Gates, Richard Branson and Kimbal Musk, as well as two giant players in the animal protein and feed space, Cargill and Tyson Foods. The company says its latest funding round has brought in $161 million in new investment.
