Prominent scientist who said lab-leak theory of covid-19 origin should be probed now believes evidence points to Wuhan market – Washington Post

The location of early coronavirus infections in late 2019 in Wuhan, China, suggests the virus probably spread to humans from a market where wild and domestically farmed animals were sold and butchered, according to a peer-reviewed article published Thursday in the journal Science that is the latest salvo in the debate over how the pandemic began.

Where Are We in Hunting for the Coronavirus’s Origin? – Bloomberg

Almost two years after Covid-19 touched off the worst pandemic in more than a century, scientists have yet to determine its origins. The closest related viruses to SARS-CoV-2 were found in bats some 1,000 miles (1,600 kilometers) from the central Chinese city of Wuhan, where the disease erupted in late 2019. Initially, cases were tied to a fresh food market and possibly the wildlife sold there. An investigation in early 2021 highlighted the possibility that certain mammals acted as a vector, transferring the virus from bats to humans. More politically charged theories allege the virus accidentally escaped from a nearby research laboratory, or entered China from another country via imported frozen food. Amid all the posturing, governments and scientists agree that deciphering the creation story is key to reducing the risk of future pandemics.

The Pandemic’s Next Turn Hinges on Three Unknowns – The Atlantic

Winter has a way of bringing out the worst of the coronavirus. Last year, the season saw a record surge that left nearly 250,000 Americans dead and hospitals overwhelmed around the country. This year, we are much better prepared, with effective vaccines—and, soon, powerful antivirals—that defang the coronavirus, but cases seem to be on the rise again, prompting fears of another big surge.

Coronavirus FAQ: What is long COVID? And what is my risk of getting it? – NPR

One of the most frightening aspects of COVID-19 now seems to be the potential that symptoms could linger after an infection. What is my risk of having long COVID-19 if I become infected? And does being vaccinated change that?

Georgetown immunologist who has accurately predicted coronavirus trends says there are only 3 ways the pandemic could end—and you really don’t want option 2 or 3 – Fortune

In the spring of 2020, the CEO of Enochian BioSciences and professor at Georgetown University Medical Center’s Department of Medicine told The Hill that the following fall could see another wave, and it would likely be “more virulent.” He’s also spoken out about the need to equally distribute resources when it comes to fighting the COVID-19 pandemic, and the need for a globally “coordinated response.”

Chronic Olfactory Loss Plagues Many With COVID-19 – MedPageToday

As many as 1.6 million people in the U.S. may have chronic olfactory dysfunction because of SARS-CoV-2, a new analysis suggested. Based on new daily cases of COVID-19, acute incidence of COVID olfactory problems, and rates of recovery, more than 700,000 people — and possibly up to 1.6 million — may have chronic olfactory dysfunction lasting 6 months or longer, reported Jay Piccirillo, MD, of Washington University School of Medicine in St. Louis, and co-authors.

New Clues to Delta Variant’s Spread in Studies of Virus-Like Particles – NIH Director’s Blog

About 70,000 people in the United States are diagnosed with COVID-19 each and every day. It’s clear that these new cases are being driven by the more-infectious Delta variant of SARS-CoV-2, the novel coronavirus that causes COVID-19. But why does the Delta variant spread more easily than other viral variants from one person to the next?
