— "Based on the available evidence, the additional global public health risk posed by JN.1 is currently evaluated as low. Despite this, with the onset of winter in the Northern Hemisphere, JN.1 could increase the burden of respiratory infections in many countries," the WHO wrote in a statement. The Centers for Disease Control and Prevention (CDC) reports that prevalence of the strain has more than doubled in the U.S., making up 21.4% of active cases in America, compared to 8.1% the week before.

— Prof Eleanor Riley, an immunologist at the University of Edinburgh, has had her own "horrid" bout of Covid that was "much worse" than expected.She says: "People's antibody levels against Covid are probably as low now as they have been since the vaccine was first introduced."

The unseen toll: excess mortality during covid-19 lockdowns: not imposing a mandatory lockdown in Sweden resulted in a lower reduction of mobility and a substantial increase in mortality. Our results indicates that up to about 4411 of the 46554 deaths registered during this period could have been avoided had Sweden implemented a mandatory lockdown. nature31 October 2023 (LINK)

— A declassified summary of U.S. intelligence released in late 2021 noted that the reported cases are "not diagnostic of the pandemic's origins." The report added: "Even if confirmed, hospital admission alone would not be diagnostic of COVID-19 infection."

— One of the researchers was a scientist who had received significant funding from the U.S. government and whose research has focused on "how coronaviruses infect humans. At WIV, he was responsible for overseeing "gain of function" research — the controversial scientific field that involves mutating viruses to make them more deadly and more contagious—involving coronaviruses.

One allegedly led a gain-of-function research team at the WIV on SARS-like coronaviruses in the lead-up to the pandemic.

A new long Covid treatment shows promise, but U.S. insurance won't cover it and some doctors are skeptical: Here's whycnbc20 April 2023 (LINK)

— Some long Covid patients swear by hyperbaric oxygen therapy, which can cost more than $50,000 per person. Here's why some experts caution against it.

In pressurized medical-grade chambers, patients alternate between breathing pure oxygen through a mask and regular air. When you go from the former to the latter, your brain interprets the drop in pressure as a lack of oxygen, says Dr. Mohammed Elamir, a physician at The Villages, Florida-based Aviv Clinics. That triggers stem cell production and blood vessel growth in the brain, which helps the body repair itself in a variety of ways, Elamir says.

Have face masks become less effective at managing COVID?sciencefocus15 January 2023 (LINK)

— Throughout the end of 2021, children and adults who declared they "always" wore a face covering at work or school were less likely to test positive for COVID-19 compared to those who "never" or "sometimes" wore a mask. As you may expect. However, from January to May 2022, this trend faded. The likelihood that somebody who never or sometimes wore a mask would test positive was extremely similar to the chance a person who always wears a face mask would test positive. In other words, from January to May 2022, the risk of getting a COVID infection was nearly the same for those who did and didn't wear a mask. But...

— Both vaccines reduced the absolute risks of breakthrough SARS-CoV-2 infections and severe COVID-19 outcomes. However, mRNA-1273 recipients had a lower risk of COVID-19-related adverse events over 16 weeks of follow-up than the BNT162b2 vaccine recipients, particularly for reported SARS-CoV-2 infections. The findings remained comparable across periods spanning Delta and Omicron predominance and only Omicron predominance.
