Multipathogen Testing Identifies Significant Adenovirus Outbreak at South Carolina University

Reading Time: 2 minutes

In early 2022, a significant adenovirus outbreak struck a university in South Carolina, highlighting the crucial role of multipathogen PCR testing in identifying and managing such occurrences. 

The outbreak, spanning from January to May 2022, saw 195 students diagnosed with adenovirus type 4 infections. This discovery was facilitated by the use of multipathogen PCR testing, a method capable of detecting multiple respiratory viruses simultaneously. This testing method proved pivotal in not only identifying the primary virus but also in detecting other co-existing respiratory viruses in 22% of the affected students.

The study, conducted by a collaboration of health professionals and institutions, including the South Carolina Department of Health and Environmental Control and the Centers for Disease Control and Prevention, showcased the importance of comprehensive testing approaches during infectious disease outbreaks.

The findings were published in the journal Emerging Infectious Diseases.

Adenovirus infections, typically resulting in respiratory illnesses, can range from mild to severe. In this outbreak, common symptoms among the students included cough, sore throat, fever, and headache. Interestingly, the outbreak affected an equal number of male and female students, with the median age being 19 years. Most affected students were first- or second-year undergraduates, residing in on-campus dormitories, which possibly facilitated the virus’s spread due to the close living conditions.

A notable aspect of this outbreak was the co-detection of other respiratory viruses in a portion of the affected students. This included human rhinovirus/enterovirus, seasonal coronaviruses, and, in some cases, SARS-CoV-2. The presence of multiple respiratory viruses in individual patients underscores the complexity of diagnosing and managing respiratory illnesses, especially in communal settings where multiple pathogens can circulate simultaneously.

The university’s response, in collaboration with local and national health authorities, involved detailed tracking of the outbreak, including the rapid implementation of surface decontamination measures and adjustments to public health guidelines on campus. The outbreak coincided with the ongoing Covid pandemic, which influenced both the detection and the response to the adenovirus outbreak. The lifting of mandatory masking recommendations in March, coinciding with a spike in cases, highlighted the dynamic nature of managing respiratory infections during a pandemic.

This outbreak has significant implications for public health surveillance, particularly in congregate settings like universities. It demonstrates the necessity of ongoing vigilance for respiratory pathogens beyond the predominant focus on Covid. The effective use of multipathogen testing provides a model for future outbreak responses, enabling health authorities to quickly identify and respond to multiple pathogens. The study suggests that such comprehensive surveillance strategies will be crucial in managing future outbreaks, ensuring both rapid detection and effective response.
