How Useful Are Temperature Screenings for Covid?

The video discusses the use of temperature screening in public places like airports and gyms, questioning its effectiveness as a COVID-19 mitigation measure. It highlights the limitations of infrared temperature guns, such as calibration issues and environmental factors. The video explains that many COVID-19 cases are asymptomatic or do not present with fever, making temperature checks unreliable. The CDC no longer recommends temperature checks at airports, focusing on more effective measures. The video concludes that while temperature checks are not useless, they should be part of a broader strategy, not relied upon solely.
