In the middle of the coronavirus pandemic, it became more common than ever to have aContact thermometer Held until your forehead before entering a store or heading to your office. Temperature controls have become a default way to evaluate individuals for COVID-19; They are even informed in the Guidelines for Disease Control and Prevention Centers (CDC) as a reliable method for employee screening. The CDC notes thatanyone with a fever Equal to or greater than 100.4 degrees Fahrenheit should not be allowed to work or enter an installation. Of course, a fever has long been the sign reveals from any infection and it has been reported that 72% ofCoronavirus patients have fever. But now, new research claims thatTemperature controls are largely ineffective for 18 to 25 years.

A recent document published in the journalTravel medicine and infectious diseasefoundTemperature controls are not particularly reliable, especially among a younger demographic. The researchers evaluated 84 men in military training at the Swiss armed forces with a median age of 21, each of which has been diagnosed with CVIV-19. Researchersmeasured their bodily temperatures Twice a day for two weeks from the day that each patient was initially diagnosed.

What they have seen is that while their fevers were initially high, their body temperatures quickly returned to normal. After five days, one of the patients did not have a fever. In addition, 83% of patients evaluated never have ever developed fever and, with one exception, none of them suffered from a fever of more than three days.

Researchers point out that those with coronavirus areknown to be contagious For "up to 10 days after the infection", which means that these people with CIVID-19 can always rule out the contagion even if their body temperature is normal.

"Screening for fever is not sensitive enough to detect the vast majority of CVIV-19 cases in the age group between 18 and 25 years," concluded researchers. "Even a low temperature threshold value of 37.1 ° C [98.8 degrees Fahrenheit] will miss more than a third of the symptomatic cases of COVID-19 on the day of diagnosis and will result in a large number of false positives."

From June, Coronavirus began to hit a young population, with nearly half ofNew cases of coronavirus In some states, spread by people aged 18 to 35. As a result, which symptoms were considered "common" also started to change. And this includes less andless to have fever. "The youngest people often come - a little to our surprisefeverless, "William Schaffner, MD, a professor of infectious diseases at the University of Vanderbilt, said WGN9 in July.

All this means that if youth with COVID-19 have received temperature checks outside a store, their office or a border of travel, they would not have any red flag, even if they could still have the virus and infect others.

Researchers particularly want these border control measures to be aware of the inefficiency of temperature controls and recommend that they switch gears. "We advocate the evaluation of new non-invasive screening approaches, such asSalivan samples test for Sars-Cov-2 With a quick follow-up on the positives, "researchers note." This can be a fast and more sensitive alternative to the projection of body temperature at the borders.
