Pls kindly advise:
1) What should public service workers manning the frontline do to keep themselves (& their family members) safe if they are handling a large number of public?
2) How to differentiate between nasal allergy/flu or cold/Covid-19?
3) How accurate are forehead temperate scanners? Some say they have a 1 degree celsius difference. What temperature is considered having a fever for forehead temperature scanner?
