BQ.1 and BQ.1.1 are among the more than 300 sub-lineages of the Omicron variant circulating globally, 95 percent of which are direct descendants of BA.5, according to the WHO. In early July, BA.5 became the dominant subvariant of the coronavirus circulating in the United States, but in October it started giving way to BQ.1 and […]

Despite the fact that they’re driving a spurt in COVID cases, the World Health Organization (WHO) says XBB and BQ.1 are not different enough from each other, or from other Omicron lineages, to warrant labelling them new variants of concern. Variants of concern are those that show increased transmissibility, virulence or change in clinical disease,

When monkeypox cases in Europe began to decline this summer, researchers’ first question was: Is it real? Some worried that people might not be getting tested because of receding fears of the virus, coupled with strict isolation requirements for patients. “They might be reluctant to be confirmed and be told not to go out at

In a US government lab in Bethesda, Maryland, virologists plan to equip the strain of the monkeypox virus that spread globally this year, causing mostly rash and flulike symptoms, with genes from a second monkeypox strain that causes more serious illness. Then they’ll see whether any of the changes make the virus more lethal to

Twitter exploded with outrage last week about a study in which scientists engineered the spike protein of Omicron—the fast-spreading but relatively mild variant of SARS-CoV-2 that’s now pervasive—into a deadlier strain of the coronavirus found in Washington state early in the pandemic. www.science.org/content/article/news-glance-climate-justice-ethical-mask-wearers-and-cdc-under-trump The objective was to learn whether the protein alone explains Omicron’s lower
