(Reuters) - The United States last week reported a 23% drop in new cases of COVID-19 and a 16% fall in the number of people hospitalized with the virus, with both figures declining for a fifth week in a row.

A new study identifies seven U.S. virus variants with the same worrying mutation.

As Americans anxiously watch the spread of coronavirus variants that were first identified in Britain and South Africa, scientists are finding a number of new variants that seem to have originated in the United States — and many of them may pose the same kind of extra-contagious threat.

In a study posted on Sunday, a team of researchers reported seven growing lineages of the coronavirus, spotted in states across the country. All have gained a mutation at the exact same spot in their genes.
