The FBI concluded with "moderate confidence" that COVID-19 may have been created in a laboratory, based in part on genomic analysis conducted by scientists at the National Center for Medical Intelligence. [98] On 20 March 2023, the COVID-19 Origin Act of 2023 was signed into law. On June 23, 2023, the Biden administration released its report ...
Assessment on COVID-19 Origins [1] is a 2021 United States intelligence report, which was commissioned on May 26, 2021 by President Joe Biden and declassified in August of the same year. Biden initially ordered his intelligence services to "redouble efforts" concerning the origins of the SARS-CoV-2 virus. [ 2 ]
The most similar known viruses to SARS-CoV-2 include bat coronaviruses RpYN06 with 94.5% identity, [15] and RmYN02 with 93% identity [18] RaTG13 was not the direct progenitor of SARS-CoV-2. [19] Temmam et al. found no serological evidence for exposure to BANAL-52 among bat handlers and guano collectors in the area of Laos where it was sampled. [20]
Covid-19's "transmissibility, asymptomatic spread, and the long-term, chronic health problems that some survivors are suffering from months later, the ability of droplets versus aerosols," and of ...
Natural selection produced the human coronavirus by mutation in humans. The spike protein of SARS-CoV-2 interacts with furin, an enzyme found in human cells. Furin-like sites are present in other viruses such as HIV and Ebola virus, but not in bat or pangolin coronaviruses, suggesting that the specific furin interaction developed only in humans.
The risk of respiratory syncytial virus, or RSV, is on the rise, along with that of other illnesses including the flu, stomach flu and COVID-19.
According to the Centers for Disease Control, COVID-19 hospitalizations rose by 10% in the week of July 15, as compared to the previous week, from 6,444 hospitalizations to 7,109.
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
