What’s the matter Turkeytop, can dish it out but can’t take it.

Help me out here. What have I been dishing out and what have I been unable to take?

Interesting read on 2021 predictions...

June 2021. The world has been in pandemic mode for a year and a half. The virus continues to spread at a slow burn; intermittent lockdowns are the new normal. An approved vaccine offers six months of protection, but international deal-making has slowed its distribution. An estimated 250 million people have been infected worldwide, and 1.75 million are dead.

Scenarios such as this one imagine how the COVID-19 pandemic might play out1. Around the world, epidemiologists are constructing short- and long-term projections as a way to prepare for, and potentially mitigate, the spread and impact of SARS-CoV-2, the virus that causes COVID-19. Although their forecasts and timelines vary, modellers agree on two things: COVID-19 is here to stay, and the future depends on a lot of unknowns, including whether people develop lasting immunity to the virus, whether seasonality affects its spread, and — perhaps most importantly — the choices made by governments and individuals. “A lot of places are unlocking, and a lot of places aren’t. We don’t really yet know what’s going to happen,” says Rosalind Eggo, an infectious-disease modeller at the London School of Hygiene & Tropical Medicine (LSHTM).

“The future will very much depend on how much social mixing resumes, and what kind of prevention we do,” says Joseph Wu, a disease modeller at the University of Hong Kong. Recent models and evidence from successful lockdowns suggest that behavioural changes can reduce the spread of COVID-19 if most, but not necessarily all, people comply.

New Cause of COVID-19 Blood Clots Identified
A new study reveals the virus triggers production of antibodies circulating through the blood, causing clots in people hospitalized with the disease.

Blood clots continue to wreak havoc for patients with severe COVID-19 infection, and a new study explains what may spark them in up to half of patients.

The culprit: an autoimmune antibody that’s circulating in the blood, attacking the cells and triggering clots in arteries, veins, and microscopic vessels. Blood clots can cause life-threatening events like strokes. And, in COVID-19, microscopic clots may restrict blood flow in the lungs, impairing oxygen exchange.

Outside of novel coronavirus infection, these clot-causing antibodies are typically seen in patients who have the autoimmune disease antiphospholipid syndrome. The connection between autoantibodies and COVID-19 was unexpected, says co-corresponding author Yogen Kanthi, M.D., an assistant professor at the Michigan Medicine Frankel Cardiovascular Center and a Lasker Investigator at the National Institutes of Health’s National Heart, Lung, and Blood Institute.

“In patients with COVID-19, we continue to see a relentless, self-amplifying cycle of inflammation and clotting in the body,” Kanthi says. “Now we’re learning that autoantibodies could be a culprit in this loop of clotting and inflammation that makes people who were already struggling even sicker.”
