Diagnostic tests are used to detect current, active infections of the SARS-CoV-2 virus. Diagnostic tests can be antigen based (“rapid antigen” tests), which look for protein markers on the outside of the virus, or they can be molecular based (including PCR, LAMP, CRISPR), which look for viral genomic material specific to SARS-CoV-2. Molecular based tests that amplify […]

Authors: CDC Summary of Recent Changes Updates as of May 13, 2021 Updated guidance based on new published studies on antigen test performance. Clarification about which NAATs should be used for confirmatory testing. Considerations for people who have had previous SARS-CoV-2 infections and those who have been fully vaccinated. Two new antigen testing algorithms, one […]
Authors: Myron S. Cohen, M.D. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes coronavirus disease 2019 (Covid-19), has generated a worldwide pandemic. The interruption of its spread depends on a combination of pharmacologic and nonpharmacologic interventions. Initial SARS-CoV-2 prevention includes social distancing, the use of face masks, environmental hygiene, and hand washing.1 Although […]

Authors: Laura E. Lamb ,Sarah N. Bartolone,Elijah Ward,Michael B. Chancellor Abstract Novel Corona virus/Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2 or 2019-nCoV), and the subsequent disease caused by the virus (coronavirus disease 2019 or COVID-19), is an emerging global health concern that requires a rapid diagnostic test. Quantitative reverse transcription PCR (qRT-PCR) is currently the standard […]

Full-text and metadata dataset of COVID-19 and coronavirus-related scholarly articles optimized for machine readability and made available for use by the global research community. In response to the COVID-19 pandemic, the Allen Institute for AI has partnered with leading research groups to prepare and distribute the COVID-19 Open Research Dataset (CORD-19). This dataset is a free resource […]
Authors: Bethany Milliron, Travis S Henry, Srihari Veeraraghavan, Brent P Little Bronchiectasis is permanent irreversible dilatation of the airways and occurs in a variety of pathologic processes. Recurrent infection and inflammation and the resulting chemical and cellular cascade lead to permanent architectural changes in the airways. Bronchiectasis can confer substantial potential morbidity, usually secondary to […]
