The hunt for COVID-19 s origin and the lab leak theory

The complex, messy hunt for COVID-19 s origin and the lab leak theory CNET 6 days ago © Andre Malerba/Bloomberg via Getty Images Bats are planets of viruses. The closest known virus to SARS-CoV-2 was discovered in a bat in 2013.  Of the many mysteries kindled by the coronavirus pandemic, the question of where SARS-CoV-2 originated has been the most difficult to answer.  No matter how history ultimately writes the pandemic s origin story, it was, almost certainly, an unfortunate accident. But what kind of accident? That urgent question is key to preventing the emergence of a SARS-CoV-3 or a COVID-29, but an uneasy tension has been building around the answer. Two conflicting narratives have materialized since the first cases were detected in the central Chinese city of Wuhan a year ago, exposing a deep chasm between researchers exploring COVID-19 s beginnings.

What We Know and Don t Know About the Coronavirus Variants

By now, you have likely heard about different variants that first raised trouble in the United Kingdom, South Africa, Brazil, and now maybe California though the jury is very much out on whether that last one is cause for concern. To make a messy alphabet soup even more jumbled, these variants have unwieldy names, and they each contain mutations with unwieldy names of their own. The result is that people are left trying to differentiate among B.1.1.7 and N501Y and E484K and C-3PO.

The drugs, known as monoclonal antibodies, are lab-engineered versions of antibodies that simulate the body’s natural immune response to viruses. They are considered among the most promising for preventing infected patients from developing severe or fatal symptoms and keeping them out of the hospital. After catching Covid-19, President Trump was treated with one of the drugs and credited it with his speedy recovery. Doctors say the drugs will continue to be important treatments for the foreseea
