From the early outbreak of the COVID-19 pandemic, rumors and speculation arose about the possible lab origins of SARS-CoV-2, the causative agent of the COVID-19 disease. . Different versions of the lab origin hypothesis present different scenarios in which a bat-borne progenitor of SARS-COV-2 may have spilled over to humans, including a laboratory-acquired infection of a natural or engineered vi
This registry based, multi-center, multi-country data provide provisional support for the use of ECMO for COVID-19 associated acute hypoxemic respiratory failure. Given that this is a complex technology that can be resource intense, guidelines exist for the use of ECMO during the COVID-19 pandemic. [85] [86] [87]
[2] [16] Following a study published by The Lancet on safety concerns with hydroxychloroquine, the WHO suspended use of it from the Solidarity trial in May 2020, [197] [198] reinstated it after the research was retracted, [199] then abandoned further use of the drug for COVID-19 treatment when analysis showed in June that it provided no benefit ...

SARS-CoV-2 is the seventh known coronavirus to infect people, after 229E, NL63, OC43, HKU1, MERS-CoV, and the original SARS-CoV. [105] Like the SARS-related coronavirus implicated in the 2003 SARS outbreak, SARS‑CoV‑2 is a member of the subgenus Sarbecovirus (beta-CoV lineage B). [106] [107] Coronaviruses undergo frequent recombination. [108]
Ensitrelvir has been investigated for use as potential post-exposure prophylaxis (PEP) for SARS-CoV-2 infection. [20] [21] The SCORPIO-PEP trial, a global Phase 3 study, assessed the safety and efficacy of ensitrelvir in preventing symptomatic COVID-19 among household contacts of individuals with confirmed SARS-CoV-2 infection.
Scanning electron micrograph of SARS virions. Severe acute respiratory syndrome (SARS) is the disease caused by SARS-CoV-1. It causes an often severe illness and is marked initially by systemic symptoms of muscle pain, headache, and fever, followed in 2–14 days by the onset of respiratory symptoms, [13] mainly cough, dyspnea, and pneumonia.
The COVID-19 pandemic (also known as the coronavirus pandemic and COVID pandemic), caused by severe acute respiratory syndrome coronavirus 2 , began with an outbreak of COVID-19 in Wuhan, China, in December 2019. Soon after, it spread to other areas of Asia, and then worldwide in early 2020.
