ANALYSIS: The Delta variant and its possible future mutations

Tue, 2021-11-16 12:09 — mike kraft

Explainer-Delta dominates the world, but scientists watch for worrisome offspring The Delta variant of the SARS-CoV-2 virus now accounts for nearly all of the coronavirus infections globally, fueled by unchecked spread of the novel coronavirus in many parts of the world. The Delta variant, first detected in India in December 2020, remains the most worrisome version of the SARS-CoV-2 virus.

Why is Delta so infectious? New lab tool spotlights little noticed mutation

Fri, 2021-11-05 19:35 — mike kraft

New lab tool spotlights mutation that speeds spread of Delta variant

As the world has learned to its cost, the Delta variant of the pandemic coronavirus is more than twice as infectious as previous strains. Just what drives Delta’s ability to spread so rapidly hasn’t been clear, however. Now, a new lab strategy that makes it possible to quickly and safely study the effects of mutations in SARS-CoV-2 variants has delivered one answer: a little-noticed mutation in Delta that allows the virus to stuff more of its genetic code into host cells, thus boosting the chances that each infected cell will spread the virus to another cell.
