Comparative Effectiveness of Single vs Repeated Rapid SARS-CoV-2 Antigen Testing Among Asymptomatic Individuals in a Workplace Setting.

This comparative effectiveness research study assesses the accuracy of single vs repeated antigen testing for diagnosis of COVID-19 among asymptomatic individuals in a workplace setting.

Monoclonal Antibody Therapy in a Vaccine Breakthrough SARS-CoV-2 Hospitalized Delta (B.1.617.2) Variant Case.

We present two Delta (B.1.617.

Use of a multiplex DNA extraction PCR in the identification of pathogens in travelers' diarrhea.

Background: Diarrhea is one of the most common ailments afflicting travelers with attack rates of 30-40% for medium to high-risk destinations. As travelers' diarrhea (TD) is syndromic and caused by a wide range of pathogens, including bacteria, parasites and viruses, multiplex deoxyribonucleic acid (DNA) extraction polymerase chain reaction (PCR) technology can be useful for determining the etiology of TD pathogens.

Objective: The goal of this retrospective study was to produce clinically relevant and useful data on gastrointestinal illness related to travel identified by culture-independent methods of diagnosis-use of the multiplex DNA extraction PCR platform (BioFire FilmArray GI Panel) and to describe the use of this technology in detection of enteric pathogens.
