The research was recently published by a team at the Academy of Military Medical Sciences in the federal agency’s Emerging Infectious Diseases Journal. “The aerosol distribution characteristics … indicate that the transmission distance of [COVID-19] might be 4 m (more than 13 feet) ” the report says.

Additionally, the research found that the virus can linger on shoes and function as carriers of the coronavirus.

“Furthermore, half of the samples from the soles of the ICU medical staff shoes tested positive,” the researchers wrote of samples taken at Huoshenshan Hospital in Wuhan, China. “Therefore, the soles of medical staff shoes might function as carriers.”

The Centers for Disease Control and Prevention (CDC) has eased some of the physical distancing guidelines for people who’ve been exposed to the new coronavirus, SARS-CoV-2.

The guidance, which updated Wednesday, will allow asymptomatic people who’ve been exposed to the virus to go back to work as long they take their temperature twice a day, practice physical distancing, and wear a face mask.

The new guidance has sparked a fiery debate among health experts.

Some think letting people exposed to the new coronavirus get back to essential work is crucial to keep certain essential businesses and hospitals in motion.

Others believe doing so will open the floodgates and trigger a second wave of COVID-19.

You're not supposed to reuse the common N95 filtering facepiece respirator mask. But given that they're almost impossible to find or impossible to afford amid the coronavirus pandemic, here are some acceptable methods to decontaminate and reuse common N95 masks.

Method 2: Steaming or boiling

Dr. Tsai says submerging an N95 in 125C/260F degree steam or boiling water for 3 minutes will disinfect the mask without significantly reducing its filtration efficiency (FE). Don't excessively stir the mask if you boil it, use only enough manipulation to keep it submerged. If your mask has paper outer and inner layers, neither the steam or boiling methods are advisable as they will disintegrate those paper layers that hold the filter medium between them.

Our ability to reopen the economy ultimately depends on our ability to better understand the spread and risk of the virus,” said Betsey Stevenson, a University of Michigan economist who worked on the White House Council of Economic Advisers under President Barack Obama. “It’s also quite likely that we will need to figure out how to reopen the economy with the virus remaining a threat.”

Public health experts are beginning to make predictions about when coronavirus infection rates will peak. Economists are calculating when the cost of continuing to shutter restaurants, shopping malls and other businesses — a move that has already pushed some 10 million Americans into unemployment, with millions more on the way — will outweigh the savings from further efforts to slow the virus once the infection curve has flattened out.

It doesn’t simply rely on being coughed on or respiratory secretions within a six-foot radius of a patient,” he said. “Being airborne would allow a virus to travel further than that. There have been hints.”

Air samples taken inside hospitals, in COVID-19 patients’ rooms and the hallways outside, tested positive for the coronavirus, according to University of Nebraska research. The study is published on a pre-publication research site, but is not yet peer-reviewed.

The samples were taken farther than 6 feet away from patient beds. Analysis of the samples found in the air did not indicate the presence of viral replication.

A university post noted that this was not conclusive evidence that the virus is airborne, and that further research is needed to see if live virus was captured and determine the risk of transmission through the air.

Q: What mistakes are other countries making?

A: The big mistake in the U.S. and Europe, in my opinion, is that people aren’t wearing masks. This virus is transmitted by droplets and close contact. Droplets play a very important role—you’ve got to wear a mask, because when you speak, there are always droplets coming out of your mouth. Many people have asymptomatic or presymptomatic infections. If they are wearing face masks, it can prevent droplets that carry the virus from escaping and infecting others.

Q: What about other control measures? China has made aggressive use of thermometers at the entrances to stores, buildings, and public transportation stations, for instance.

A: Yes. Anywhere you go inside in China, there are thermometers. You have to try to take people’s temperatures as often as you can to make sure that whoever has a high fever stays out.

And a really important outstanding question is how stable this virus is in the environment. Because it’s an enveloped virus, people think it’s fragile and particularly sensitive to surface temperature or humidity. But from both U.S. results and Chinese studies, it looks like it’s very resistant to  ...
