1 天前 · SARS-CoV-2 Omicron breakthrough infection (BTI) induced better protection than triple vaccination. To address the underlying immunological mechanisms, we studied antibody and T cell response dynamics during vaccination and after BTI.. Each vaccination significantly increased peak neutralization titers with simultaneous increases in circulating spike-specific T-cell frequencies. Neutralization ...
1 天前 · SARS-CoV-2 RNA was detected using the SARS-CoV-2 Detection RT-qPCR Kit for Wastewater (Takara Bio, Shiga, Japan) and QuantStudio 5 Real-Time PCR System (Thermo Fisher Scientific, Waltham, MA, USA).
5 天前 · The history of coronaviruses is an account of the discovery of the diseases caused by coronaviruses and the diseases they cause. It starts with the first report of a new type of upper-respiratory tract disease among chickens in North Dakota, U.S., in 1931. The causative agent was identified as a virus in 1933.
1 天前 · However, there is ongoing global transmission of SARS-CoV-2 and evolution of variant strains, with the potential to cause more serious illness. Only limited antiviral options are available to reduce symptomatic illness and disease progression. 2-4 Unlike monoclonal antibodies, which target epitopes on the viral surface, small-molecule ...
1 天前 · The study also found that long-haul flights with enforced masking had almost no reports of SARS-CoV-2 transmission within the aircraft despite meals being served. The researchers believe the ...
1 天前 · The detection and differentiation of SARS-CoV-2 variants are vital for disease management and timely patient isolation. Although qRT-PCR has been the standard method, our OmiCrisp assay has shown superior results in identifying Omicron and non-Omicron variants. The World Health Organization advises ongoing sewage surveillance to monitor community viral load, accounting for both symptomatic and ...
2 天前 · Scientifically accurate atomic model of the external structure of SARS-CoV-2. Each "ball" is an atom. COVID-19 testing involves analyzing samples to assess the current or past presence of SARS-CoV-2. The two main types of tests detect either the presence of the virus or antibodies produced in response to infection.
