Recently, the Director-General of Health Services in the Ministry of Health released a warning. In a letter, he said that one could still get infected by inappropriately using the N-95 masks, particularly those come with valved respirators. The letter says that the “inappropriate use” of N-95 masks by the public and designated health workers could be risky. "They are detrimental to the measures adopted for its containment," the Centre also warned in a letter to the principal secretaries of health and medical education of states.


In India, wearing a mask in public places is now mandatory.

It is also highly advisable to use homemade protective gear for face and mouth, said the Ministry of Health. DGHS Rajiv Garg wrote in the letter that valved respirator N-95 masks "does not prevent the virus from escaping out of the mask."

"In view of the above, I request you to instruct all concerned to follow the use of face/mouth cover and prevent inappropriate use of N-95 masks," the letter read.
