New study cautions that relying on fever checks as a single screening tool for schools and businesses could lead to a false sense of security.
Fever checks have widely become the first level of coronavirus detection as businesses, stores and schools try to reopen, but a new study cautions that relying on them as a single screening tool could lead to a false sense of security.
Fever is generally the first symptom of a coronavirus infection, according to a study from the University of Southern California, followed by cough, nausea, vomiting and lower gastrointestinal symptoms, such as diarrhea. For the study, researchers used World Health Organization data, which included information on nearly 60,000 confirmed cases of COVID-19, to model the order of symptoms. Limitations of the study, published last week in a, include that the cases were almost all from China during the early days of the pandemic, before other types of symptoms were recognized.
While a temperature check can detect people who are showing symptoms, there are a significant number of people who could be contagious that don't develop a fever, said study co-author Peter Kuhn, a professor of biological sciences, medicine and engineering at USC.Let our news meet your inbox.
