SARS-CoV-2 variants have higher transmissibility and a longer infectious period

Researchers analyzed data on three variants of concern and found that viral loads were higher and infection lasted longer for the B.1.1.7 variant. They all were more infectious than the original strain, and transmissibility also depended on population demographics.

Researchers identify a novel SARS-CoV-2 variant (with the V1230L mutation) in West Bengal, India

Researchers identify a novel SARS-CoV-2 variant (with the V1230L mutation) in West Bengal, India Researchers analyzed 2,000 viral genomes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the causative agent of coronavirus disease 2019 (COVID-19) – sequences obtained from India and found a new variant that could be more infectious and transmissible. The continued transmission of SARS-CoV-2 has led to its mutating several times. Many of the new mutations are on the virus spike protein, which has helped viral fitness and survivability by making it more infectious and giving it the ability to evade the immune system and neutralizing antibodies. Several variants of concern have emerged in different parts of the globe, like the B.1.1.7 in the United Kingdom, the B.1.351 in South Africa, and the P.1 strain in Brazil. Two new variants have recently been reported from India, the B.1.617 and B.1.618 strains, characterized by several mutations in the spike protein.

Researchers develop a method to detect SARS-CoV-2 and variants simultaneously

Researchers develop a method to detect SARS-CoV-2 and variants simultaneously Researchers demonstrate a method of detecting the presence and mutations in the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus using the smaller and cheaper Oxford Nanopore sequencer, a method they believe could make pandemic surveillance faster and cheaper. The coronavirus disease 2019 (COVID-19) pandemic has led to great research efforts in viral diagnostics. New methods have been developed to reduce diagnosis time and cost, increase sensitivity and specificity, and allow large-scale diagnostic methods to be carried out. Several strategies were proposed that used massive parallel DNA sequencing for large-scale diagnostics. These methods used DNA molecular barcodes during sample preparation, pooling the samples for doing the assay “in one run,” and breaking down the results using bioinformatics processing.
