CDC Estimate: Nearly Twice As Many Had Covid Than US Case Counts Reveal
Based on antibody blood tests, the CDC says that 140 million Americans have likely contracted covid-19. And that estimate may be low because the analyzed samples were only through late January, when the highly contagious omicron variant was still surging. The data also indicates that a majority of kids have likely been infected.

The estimates, compiled by the Centers for Disease Control and Prevention, show that about 43 percent of the country has been infected by the virus. The study shows that the majority of children have also been infected. (Keating, 2/28)

New Variant Of Omicron Detected In Maine
Maine health officials have identified a new “lineage” of the COVID-19 omicron variant called BA.2 in two instances.

What Is Long Covid? Current Understanding About Risks, Symptoms And Recovery
The condition known as long covid continues to frustrate its sufferers, baffle scientists and alarm people who are concerned about being infected by the coronavirus. The term, a widely used catchall phrase for persistent symptoms that can range from mild to debilitating and last for weeks, months or longer, is technically known as Post-Acute Sequelae of SARS-CoV-2 infection, or PASC.

Nevada Emphasizes Therapeutics As New COVID-19 Cases Plummet
As Nevada’s COVID-19 case rates plummet to their lowest levels since last summer, state health officials are turning more attention to therapeutic treatments for those who can’t get vaccinated or are most at risk of severe illness or death.
