May 16, 2024 · The benefit of having a COVID-19 At-Home Test available The SARS-CoV-2 virus causes respiratory tract infection. It is transmitted mainly via respiratory droplets after close contact, and primary viral replication is presumed to occur in mucosal epithelium of the upper respiratory tract (nasal cavity and pharynx). 2 At these locations viral load peaks within the first week after symptom onset ...
May 15, 2024 · To the Editor: The letter by Herbert et al. (Feb. 22 issue)1 explores persistent false positive results on SARS-CoV-2 rapid antigen tests but overlooks various factors, such as interfering substanc...
Apr 25, 2024 · Among participants with SARS-CoV-2 infection, the percentages of positive antigen, RT-PCR, and culture results were calculated each day from the onset of symptoms or, in asymptomatic persons, from the date of the first positive test result. Antigen test sensitivity was calculated using RT-PCR and viral culture as references.
May 14, 2024 · Between Nov 30, 2020 and Feb 11, 2022, a total of 14 773 samples from 7675 employees were tested for SARS-CoV-2 by both RT-PCR and Ag-RDT. We found a negative association between immunisation status and Ag-RDT sensitivity in symptomatic employees, with an observed sensitivity of 82% (94% highest posterior density interval [HPDI] 78–86) in immunologically naive participants compared with 73% ...
Apr 26, 2024 · The most commonly detected co-infections were rhinovirus/enterovirus (6.9%), respiratory syncytial virus (5.2%), and non–SARS-CoV-2 Coronaviridae (4.3%). This report yielded higher viral co-pathogen rates than earlier COVID-19 studies but similar to the co-infection rates of many standard respiratory viral illnesses.
