Abstract We assessed the relationship between antigen and reverse transcription PCR (RT-PCR) test positivity successful virus isolation. found that results were more predictive of recovery than RT-PCR results. However, was isolated from some antigen-negative RT-PCR‒positive paired specimens, providing support for Centers Disease Control Prevention testing algorithm.
Abstract Using multipathogen PCR testing, we identified 195 students with adenovirus type 4 infections on a university campus in South Carolina, USA, during January–May 2022. We co-detected other respiratory viruses 43 (22%) students. Continued surveillance of circulating is needed to prevent virus infection outbreaks congregate communities.
Abstract Background Human adenoviruses (HAdVs) can cause outbreaks of flu-like illness in university settings. Most infections healthy young adults are mild; severe illnesses rarely occur. In Fall 2022, an adenovirus outbreak was identified students. Methods HAdV cases were defined as students 17–26 years old who presented to the University Health Service or nearby emergency department with symptoms (eg, fever, cough, headache, myalgia, nausea) and had confirmed by polymerase chain reaction...
