The first line of defense against coronavirus: Try soap, not a mask

• Update: You were told no mask if you don’t have coronavirus. That might be wrong.

For all the high-tech, high-intellect lab work that's being done around the globe to protect humans from coronavirus, it's the decidedly low-tech precautions — spoiler alert: wash your hands — that are the most effective as a first-line defense.

Perhaps more glamorous advice is likely to stick for people who otherwise dismiss tips like “keep your cough to yourself,” mused Jay Fiedler, director of the Michigan Department of Health and Human Services’ emergency preparedness and response division.

The best advice to fight respiratory illnesses — whether caused by influenza, common cold viruses, according to the U.S. Centers for Disease Control & Prevention:

• Wash hands often with soap and water for at least 20 seconds. It’s especially important after using the bathroom, before eating, and after blowing your nose, coughing or sneezing.
• No soap and water? Use an alcohol-based hand sanitizer with at least 60 percent alcohol.
• Avoid touching your eyes, nose and mouth with unwashed hands.
• Avoid close contact with people who are sick.

• If you’re sick, stay home.
• Cover your cough or sneeze with a tissue, then throw the tissue in the trash.
• Clean and disinfect frequently touched objects and surfaces using a regular household cleaning spray or wipe.
• “Everyone wants us to say something like, ‘Oh, you should wear a mask.’ We're not gonna say that,” Fiedler said.

The CDC specifically states that it does not advise healthy U.S. residents to wear masks because “this virus is not currently spreading in the community in the United States.” Other health experts question whether readily available surgical-type masks work against coronavirus.

“I wish we had something different than what we always preach for cold and flu season. But it’s ‘Keep your cough to yourself,’ and ‘Wash your hands,’” Fiedler said. 

“The message may be old and tired, and people are like ‘Whatever. It’s the health department.’ But it’s really important.”
