variants of interest, variants of concern and variants of high consequence. Some variants spread more easily and quickly than other variants, which may lead to more cases of COVID-19. An increase in the number of cases will put mo...
Currently there are five coronavirus strains classified by the CDC as "variants of concern." Besides the two detected in California, the other three are B.1.1.7, which was originally detected in Britain; B.1.351, which was initially discovered in South Africa; and P.1 strain which was first...
variants of concern(VOCs)by the World Health Organization(WHO).To better assess the role of imported SARS-CoV-2 surveillance and the prevalence of VOCs in 2021,the genomic surveillance data of SARS-CoV-2 from imported COVID-19 cases of 2021 in the mainland of China were analyzed.Methods:...
To ensure a proactive rather than reactive response, the Department of Health and Human Services (HHS) established a SARS-CoV-2 Interagency Group (SIG) to improve coordination among CDC, the National Institutes of Health (NIH), the Food and Drug Administration (FDA), the Biomedical Advanced Res...
Rodney Rohde, PhD, MS, SM(ASCP)CM, SVCM, MBCM, FACSc:Madeline, in your work, do you talk about the differences between variants of concern and variants of interest, or that type of information around these strains? Madeline King, PharmD, BCIDP:That’s a great question. In the clinical...
COVID-19 remains a global health concern in 2024, with the XBB.1.5 variant remaining the dominant strain. The symptoms of the XBB.1.5 variant are similar to those of previous strains. High-risk groups for COVID-19 remain the same as last year, and it's essential to continue taking preve...
In addition, the B.1.427 and B.1.429 variants, two coronavirus strains first detected in the U.S. state of California, are also being closely monitored by the CDC. The five coronavirus strains are currently classified by the CDC as "variants of concern," as evidence shows an increase in ...
Experts use a rating system to determine how carefully a variant needs to be watched. A strain will be labeled a variant of concern, or VOC, if, compared to other strains: It spreads faster. It causes more serious symptoms, sending more people to the hospital or causing moredeaths. ...
Under the new system, the variants of concern take on the following names: the previously so-called British variant B.1.1.7 becomes Alpha; the B.1.351 first discovered in South Africa becomes Beta, while the Brazilian P.1 becomes Gamma. ...
Among the numerous variants, the WHO, CDC (USA) and European Centre for Disease Prevention (ECDC) (Europe) highlight some as significant ones and categorize them into two subgroups: variants of concern (VOCs) and variants of interest (VOIs), which are updated when required [51]. VOCs ...
