Jul 10, 2023 · COVID-19 (coronavirus disease 2019) is a disease caused by a virus named SARS-CoV-2. It can be very contagious and spreads quickly. Over one million people have died from COVID-19 in the United States. COVID-19 most often causes respiratory symptoms that can feel much like a cold, the flu, or pneumonia. COVID-19 may attack more than your lungs ...

El SARS-CoV-2 (SARS-2 a partir de ahora) tiene un diámetro de 50-200 nm ( fig. 1 A). De sus proteínas de superficie, la glicoproteína Spike o “S” es la que se une a la célula del huésped a través de los receptores para la enzima convertidora de angiotensina II (ECA II) 3.
Oct 23, 2020 · SARS-CoV-2 is an enveloped β-coronavirus, with a genetic sequence very similar to SARS-CoV-1 (80%) and bat coronavirus RaTG13 (96.2%). 2 The viral envelope is coated by spike (S) glycoprotein, envelope (E), and membrane (M) proteins ( fig 1 ). Host cell binding and entry are mediated by the S protein. The first step in infection is virus ...
Apr 5, 2023 · In late December 2020, a new SARS-CoV-2 lineage was identified to be expanding rapidly in parts of the United Kingdom, carrying a large number of mutations in the spike region 126, 127. This ...
Nov 20, 2023 · Since 2020, SARS-CoV-2, the virus that causes COVID-19, has been spreading and changing globally. These changes have led to the detection of variants in many countries around the world. The more significant of these variants are grouped in three different ways – variants under monitoring, variants of interest and variants of concern.
Apr 4, 2020 · The genome of the new coronavirus shows similarities to other β-CoV found in bats. 20 SARS-CoV-2 is 96.2% identical to a bat CoV RaTG13, whereas it shares 79.5% identity to SARS-CoV. It can therefore be assumed that the virus originally came from bats and has been transmitted over time to other animal hosts and ultimately to humans.
