Post Comes to Premature Conclusions About COVID-19 Omicron Variant Severity

It’s not known yet whether the omicron variant causes more or less severe COVID-19 than the delta variant, although some preliminary indications suggest omicron infections might be milder.

Basketball Star Bradley Beal’s Misleading Comments About COVID-19

Basketball Star Bradley Beal’s Misleading Comments About COVID-19

NBA star Bradley Beal made some misleading comments — shared in viral video clips — about the effectiveness of COVID-19 vaccines.

COVID-19: The Unvaccinated Pose a Risk to the Vaccinated

Q: How do people who have not been vaccinated against COVID-19 pose a risk to people who have been vaccinated?

All of the authorized COVID-19 vaccines are effective at preventing symptomatic disease. Yet Fox News host Tucker Carlson baselessly casts doubt on the effectiveness of the vaccines, because federal officials urge fully vaccinated people to wear masks in public settings. 

How is COVID-19 transmitted?

The Centers for Disease Control and Prevention says SARS-CoV-2, the virus that causes COVID-19, is transmitted from person to person, “most likely” when in close contact, within about 6 feet of one another.
Scientists suspect the transmission is similar to how influenza is spread, with the virus travelling through respiratory droplets when infected people cough, sneeze, talk or breathe. 
Although “less likely,” SARS-CoV-2 also can be spread through airborne transmission,
