The deadly Covid 19 or Corona Virus we all know about is evolving day by day, so should be our (humans) tactics for protection from it. Do you know, which type of face mask protects you better from Corona Virus? If not, you are in the right place as I am going to share the photographs I took while on a visit to an OPD (Out-Patients Department) of one the leading hospitals in Kolkata. Just after entering the hospital OPD as soon as I moved towards the lift, there was a paper printed image showing the do's and don'ts while selecting the right type of mask for full protection from Covid 19 Corona Virus. Without further adieu, let us see and understand from the image itself. The facial masks with air filters is a strict no-no whereas any face mask without an air filter is right choice for better protection & prevention of Corona Virus Covid 19. Just make sure it covers up widely & perfectly. Please spread this message with others, as it can save several lives. T
