- Researchers monitoring nearly 100 men who tested positive for COVID-19 reveal that body temperature does not appear to be a reliable way to detect a coronavirus infection.
- Of 84 men between the ages of 18 and 25, only a few had a fever, and even then the fever lasted only a very short time.
- The researchers say that widespread COVID-19 testing is the only way to monitor the spread of the virus with any certainty.
Whether it’s before you go into work every day or before you go into a local clinic for an independent problem, you’ve almost certainly had to check your temperature when you entered buildings recently. This is, of course, due to the new coronavirus pandemic, and the belief is that by searching for fever and banning access to anyone who is not well visible, we can prevent the spread of the disease to others.
Unfortunately, a massive (and active) age group appears to be largely immune to the feverish symptoms of COVID-1
In a new article published in Travel medicine and infectious disease, researchers explain how monitoring body temperature in a group of nearly 100 men who tested positive for COVID-19 revealed that for those between the ages of 18 and 25, scanning for disease with body temperature is almost meaningless.
The men were members of the Swiss armed forces and had been swept up in an outbreak among soldiers. The researchers closely monitored their body temperatures twice a day for 14 days after the men tested positive for COVID-19. Unbelievably, despite some of the men initially suffering from fever, their temperatures returned to the normal range within a few days, and after five days of their diagnosis, none of the men had had a fever despite being actively contagious.
Current guidelines suggest that anyone receiving a positive diagnosis of COVID-19 should be considered contagious for at least two weeks. This means that if these men – who were largely asymptomatic – had been scanned for their body temperature for a screening agent to prevent the spread of the infection, they would have seemed completely healthy while continuing to spread the virus.
The researchers therefore concluded that screening for body temperatures at the borders to prevent the spread of COVID-19 between regions is largely ineffective, at least for this age group.
“We reinforce the WHO’s recommendation that comprehensive testing for SARS-CoV-2 is currently the only effective way available to monitor the pathway of infection and control the spread of COVID-19,” the researchers write. “Border screening temperature is a strategy that has been implemented in the past and has proven to be both expensive and inefficient. We advocate the evaluation of new non-invasive screening methods, such as testing saliva samples for SARS-CoV-2 with rapid follow-up of positive results. “
