Human to animal transmission of SARS-CoV-2 in households is common

Coronaviruses are seen in multiple mammalian species. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of the COVID-19 pandemic, is said to have passed to humans from a mammalian source and to have originated from an animal reservoir as a zoonotic pathogen.

Researchers discover how SARS-CoV-2 hijacks human cell machinery to blunt immune response

Researchers at University of California San Diego School of Medicine have discovered one way in which SARS-CoV-2, the coronavirus that causes COVID-19, hijacks human cell machinery to blunt the immune response, allowing it to establish infection, replicate and cause disease.

29 Apr 2021

New insights into how South African SARS-CoV-2 variant sacrifices tight binding for antibody evasion

The highly infectious SARS-CoV-2 variant that recently emerged in South Africa, known as B.1.351, has scientists wondering how existing COVID-19 vaccines and therapies can be improved to ensure strong protection.

Can control theory explain differences in virulence and transmission of SARS-CoV-2?

A new study discusses variations in viral pathogenicity and in transmission, which are responsible for asymptomatic infection and for superspreading events. The ability to understand this would open the way to understand how this virus behaves the way it does, in terms of its virulence, its spread, and its emergent variants of concern.
