How fast omicron’s BA.2 variant is spreading around the world – Washington Post

BA.2 has overtaken the original omicron version of the coronavirus that quickly dominated the world this winter.The impact of the BA.2 subvariant is unclear.

How Often Can You Be Infected With the Coronavirus? New York Times

The spread of the Omicron variant has given scientists an unsettling answer: repeatedly, sometimes within months.A virus that shows no signs of disappearing, variants that are adept at dodging the body’s defenses, and waves of infections two, maybe three times a year — this may be the future of Covid-19, some scientists now fear.

A ‘malignant fever’—COVID-19—surges in North Korea – Science

Over the weekend, when Kee Park saw the latest figures on what North Korea calls a “malignant fever” sweeping the country, he realized how dark the outlook had become.

The following is a summary of some recent studies on COVID-19. They include research that warrants further study to corroborate the findings and that has yet to be certified by peer review. SARS-CoV-2 could be at root of mysterious hepatitis in kids A chain of events possibly triggered by unrecognized infection with the SARS-CoV-2 coronavirus could be causing the mysterious cases of severe hepatitis reported in hundreds of young children around the world, researchers suggest.

‘A pretty big deal’: U.S. makes COVID-19 technologies available for use in developing countries – Science

The government cut a deal to provide the federally funded inventions with the COVID-19 Technology Access Pool, organized by the World Health Organization (WHO). WHO then turns over the licenses to a nonprofit, the Medicines Patent Pool (MPP), which negotiates with manufacturers interested in using the technologies to make products that can be sold worldwide. “It’s a pretty big deal,” says James Love, who directs Knowledge Ecology International, a nonprofit that advocates for sharing intellectual property to benefit the public.

FDA expected to okay Pfizer-BioNTech vaccine booster for kids 5 to 11 – Washington Post

Omicron Is Turning Out to Be a Weak Vaccine – Bloomberg

Unvaccinated people who got Covid last winter have little protection from reinfection, and even vaccinated people might be vulnerable after only a few months. A silver lining to the inconvenience of a mild Covid-19 infection is that for most people it is followed by a honeymoon period — an idyllic time when the immune system is firing on all cylinders and preventing reinfection.

Untapped Global Vaccine Stash Raises Risks of New Covid Variants – Bloomberg

The world finds itself awash in Covid-19 vaccines, but governments can’t get them into arms fast enough, as hesitancy and logistical hurdles threaten to indefinitely extend the pandemic.

Numbers skew when patients test positive but are mainly being treated for something else. Widely used methods for counting US Covid-19 hospitalizations can make vaccines appear less effective than they actually are, according to a group of Boston-based researchers.

.Scientists identify characteristics to better define long COVID – NIH

A research team supported by the National Institutes of Health has identified characteristics of people with long COVID and those likely to have it. Scientists, using machine learning techniques, analyzed an unprecedented collection of electronic health records (EHRs) available for COVID-19 research to better identify who has long COVID. Exploring de-identified EHR data in the National COVID Cohort Collaborative (N3C), a national, centralized public database led by NIH’s National Center for Advancing Translational Sciences (NCATS), the team used the data to find more than 100,000 likely long COVID cases as of October 2021 (as of May 2022, the count is more than 200,000). The findings appear in The Lancet Digital Health.

Pressure to conform to social norms may explain risky COVID-19 decisions – Science News

The pandemic has entered a murky stage, and social norms are quickly shifting, something I’ve thought a lot about lately. Many people are testing at home, or not at all. Here in Vermont, where I live, you can pick up a type of PCR test that can be taken at home. But state officials both here and elsewhere are no longer carefully monitoring the results of these tests, which means that the actual spread of coronavirus in the U.S. population remains unclear
