Each SARS-CoV-2 virion is 50–200 nanometres in diameter. Like other coronaviruses, SARS-CoV-2 has four structural proteins, known as the S , E (envelope), M , and N (nucleocapsid) proteins; the N protein holds the RNA genome, and the S, E, and M proteins together create the viral envelope.

Coronavirus disease 2019 (COVID-19) is a contagious respiratory and vascular disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The first case was identified in Wuhan, China in December 2019, though evidence suggests that the virus may have already been actively spreading months earlier in places such as Italy.

Nov 13, 2020 · Scientists know a lot about how SARS-CoV-2, the virus responsible for the COVID-19 pandemic, gets into cells. Now, in a study published October 27 in Cell, researchers have determined that mouse hepatitis virus and SARS-CoV-2, both of which are members of the β-coronavirus family, get out of cells ...
SARS-CoV-2 is a specific virus that can cause COVID-19, a disease. As WHO explains, this is similar to differentiating HIV and AIDS — HIV is a virus that causes AIDS. Outlined on their website, "People often know the name of a disease, such as measles, but not the name of the virus that causes it (rubeola)."
SARS-CoV-2 infection is transmitted predominately by respiratory droplets generated when people cough, sneeze, sing, talk, or breathe. CDC recommends community use of masks, specifically non-valved multi-layer cloth masks, to prevent transmission of SARS-CoV-2. Masks are primarily intended to reduce ...
