Irish scientists are urging businesses and organisations to be mindful of the limitations of temperature and fever screening as regards the detection of Covid-19.

As the demand for increased Covid-19 screenings intensifies, a new report from the National Metrology Laboratory (NML), which maintains national measurement standards for a range of physical quantities, says that fever and temperature tests should only be used in addition to public health guidelines and advice such as practicing social distancing, hand-washing, and the wearing of face coverings.
