COVID testing applications could enhance dangerous conduct, analysis suggests

Frequent, obligatory surveillance testing was one of many strategies deployed in some jurisdictions in an try to manage COVID-19, however new analysis reveals that such testing could have the unintended consequence of riskier conduct by these enrolled within the testing.

Based mostly on a false sense of safety, college students who participated in frequent COVID-19 testing at two universities engaged in additional conduct recognized to extend the chance of spreading the virus than they could have in any other case, in accordance with outcomes of surveys led by College of Wyoming economists.

“Latest analysis gives some proof that folks enhance dangerous conduct in response to facemask carrying and vaccines, however that is the primary research to look at the behavioral responses to obligatory testing,” wrote researchers Chian Jones Ritten, Linda Thunstrom and Todd Cherry, of UW, and J.D. Wulfhorst, of the College of Idaho. “General, (our) outcomes recommend that college students perceived that the obligatory testing coverage decreased their danger of contracting COVID-19, and that this notion led to larger participation in COVID-risky occasions.”

The analysis findings have been revealed Friday in PNAS Nexus, the open entry sister journal of the Proceedings of the Nationwide Academy of Sciences.

In the course of the fall 2020 semester, UW required all on-campus undergraduate college students to be examined for COVID twice weekly, whereas the College of Idaho examined a small random pattern of scholars weekly. Each universities required masks for all indoor occasions on campus.

The researchers surveyed college students at each universities and located that, in each instances, respondents who have been examined extra ceaselessly perceived that they have been at a diminished danger of contracting the virus. These people additionally extra ceaselessly attended “dangerous” occasions equivalent to giant and small indoor gatherings and frequented eating places and bars.

From a public well being standpoint, such conduct is problematic as a result of inaccurate and delayed take a look at outcomes can lead to individuals who consider they are not contaminated carrying the virus and infecting others. Though maybe unlikely, it’s attainable that the advantages of testing applications could possibly be solely offset by elevated viral transmission, the researchers say.

Whereas different analysis reveals that, in different contexts, the sort of danger compensation conduct is mostly small in magnitude, small behavioral modifications could result in significant will increase in illness unfold.

“These unintended penalties could pose a very giant menace to public well being when incubation occasions are quick, the virus is extremely transmissible and the chance of false negatives is excessive, equivalent to with the Omicron variant of the coronavirus,” the researchers wrote.

Apparently, the surveys discovered that girls, greater than males, understand that elevated testing reduces the chance of contracting the virus — and are, thus, extra more likely to enhance dangerous conduct than males.

General, the analysis reveals that obligatory testing applications ought to be accompanied by mitigation measures to cut back the unintended consequence of individuals participating in riskier conduct, the researchers say.

“Our findings recommend that applications with frequent testing could unintentionally enhance conduct recognized to contribute to virus unfold — the potential penalties of that are amplified by the exponential nature of viral unfold,” the researchers concluded. “Thus, when implementing obligatory testing applications to handle a pathogen, you will need to talk the applications’ limitations in defending in opposition to an infection and spotlight the potential for unintended behavioral responses.”
