Death Toll During Pandemic Far Exceeds Totals Reported by Countries, W.H.O. Says

Nearly 15 million more people died during the first two years of the pandemic than would have been expected during normal times, the organization found. The previous count of virus deaths, from countries’ reporting, was six million.

A New Covid Mystery Why haven’t cases started rising again in the U.S.?

To many people’s surprise — including mine — new Covid-19 cases in the U.S. have not begun to rise. Over the past two weeks, they have held roughly steady, falling about 1 percent, even as the highly contagious BA.2 subvariant of Omicron has become the dominant form of Covid in the U.S. Across much of Europe, by contrast, cases surged last month after BA.2 began spreading there, and many experts expected a similar pattern here. That hasn’t happened. “It has not taken off,” Michael Osterholm, a University of Minnesota epidemiologist, told me.

COVID-19 takes serious toll on heart health—a full year after recovery

From very early in the pandemic, it was clear that SARS-CoV-2 can damage the heart and blood vessels while people are acutely ill. Patients developed clots, heart inflammation, arrhythmias, and heart failure. Now, the first large study to assess cardiovascular outcomes 1 year after SARS-CoV-2 infection has demonstrated that the virus’ impact is often lasting. In an analysis of more than 11 million U.S. veterans’ health records, researchers found the risk of 20 different heart and vessel maladies was substantially increased in veterans who had COVID-19 1 year earlier, compared with those who didn’t. The risk rose with severity of initial disease and extended to every outcome the team examined, including heart attacks, arrhythmias, strokes, cardiac arrest, and more. Even people who never went to the hospital had more cardiovascular disease than those who were never infected.

The White House said it is offering a second round of free coronavirus tests to all Americans.

The White House on Monday said that it would begin offering a second round of four free at-home coronavirus tests to all American households, delivering on a pledge President Biden made last week in his State of the Union address, when he framed the offer as part of a broader effort to stay ahead of possible outbreaks and new variants.

Covid May Cause Changes in the Brain, New Study Finds

Brain scans before and after infection showed more loss of gray matter and tissue damage, mostly in areas related to smell, in people who had Covid than in those who did not.
