Its purpose is to implement a dynamic nomenclature (known as the Pango nomenclature) to classify genetic lineages for SARS-CoV-2, the virus that causes COVID-19. [4] A user with a full genome sequence of a sample of SARS-CoV-2 can use the tool to submit that sequence, which is then compared with other genome sequences, and assigned the most ...
The COVID-19 virus has not been detected in drinking water. [82] Conventional water treatment (filtration and disinfection) inactivates or removes the virus. [82] COVID-19 virus RNA is found in untreated wastewater, [82] [22] [83] [a] but there is no evidence of COVID-19 transmission through exposure to untreated wastewater or sewerage systems ...
The commercial name for the FDA approved COVID-19 vaccine from Pfizer, released August 21, 2021. It also has several other names or designators used on the actual vials. Community transmission. Main article: Community transmission. The spread of a contagious disease to an individual with no known contact with other infected populations. Contact ...
Lateral flow assays have played a critical role in COVID-19 testing as they have the benefit of delivering a result in 15–30 minutes. [31] The systematic evaluation of lateral flow assays during the COVID-19 pandemic [32] was initiated at Oxford University as part of a UK collaboration with Public Health England. A study that started in June ...
One of the most notable scientific papers that first popularized hydroxychloroquine as a COVID-19 treatment was retracted from its journal due to ethical and methodological issues. Retractions in ...
Lineage B.1.617 is a lineage of SARS-CoV-2, the virus that causes COVID-19. [1] It first came to international attention in late March 2021 after the newly established INSACOG performed genome sequencing on positive samples throughout various Indian states.
During the initial outbreak in Wuhan, China, various names were used for the virus; some names used by different sources included "the coronavirus" or "Wuhan coronavirus". [ 27 ] [ 28 ] In January 2020, the World Health Organization (WHO) recommended "2019 novel coronavirus" (2019-nCoV) [ 5 ] [ 29 ] as the provisional name for the virus.
Throughout the COVID-19 pandemic, the genome of SARS-CoV-2 viruses has been sequenced many times, resulting in identification of thousands of distinct variants. In a World Health Organization analysis from July 2020, ORF1ab was the most frequently mutated gene, followed by the S gene encoding the spike protein .
