CLAIM ID

a3461668

Thermal scanners are effective in detecting people infected with the novel coronavirus.

Statements by LSHTM and the Birmingham Watch refute the claim that thermal scanners can effectively detect COVID-19 infected people.

According to the London School of Hygiene and Tropical Medicine, for every 100 infected travellers planning to take a 12-hour flight, only 9 will be detected at entry screening upon arrival using a thermal scanner as screening is only able to detect infected travellers who are currently showing symptoms, such as fever. It means that a thermal scanner cannot detect every traveller infected with the coronavirus.

Moreover, symptoms of COVID-19 can appear two to 10 days after infection, which means that someone infected with the virus could have a normal temperature while passing through the screening process, and it could be a few days before a fever begins.

The COVID-19 pandemic has given rise to a lot of potentially dangerous misinformation. For reliable advice on COVID-19 including symptoms, prevention and available treatment, please refer to the World Health Organisation or your national healthcare authority.
