What are “fever checks,” and are they helpful?
Many people with COVID-19 develop a fever. But these people are often contagious long before they do. And some infected people don’t have any obvious symptoms at all, including a fever. Doctors call this being “asymptomatic.” Those folks are also contagious.
Having your temperature taken when entering a building is called a “fever check.” But as the WHO explains, temperature checks are useful in determining whether or not you have a fever, but they can’t detect whether you have COVID-19.
In other words, fever checks can only catch people who have a fever when they try to enter a building. But fever checks won’t catch the many contagious people who don’t have a fever.
So do your part—self-monitor for potential symptoms and stay home if you feel at all sick! And regardless of whether or not you get your temperature checked every day, you should continue to keep your social distance, wear a mask, and wash your hands!
