grocery stores, salons and other businesses have implemented temperature screening — an approach that uses a touchless scanner to measure a person’s body temperature — in an attempt to prevent the spread of the novel coronavirus.The process was made mandatory for all air travellers in Canada in mid-June.
Any passenger who shows a fever on two measurements, taken 10 minutes apart, will be asked to rebook after 14 days.However, some experts wonder whether the step is effective given a person can shed the COVID-19 virus without having a fever or any change in body temperature.
