The Centre has written to all states and union territories warning against the use of N-95 masks with valved respirators by people, saying these do not prevent the virus from spreading out and are “detrimental” to the measures adopted for its containment.
The Director-General of Health Services (DGHS) in the Ministry of Health, in a letter to the Principal Secretaries of health and medical education of states, said it has been observed that there is “inappropriate use” of N-95 masks, particularly those with valved respirators, by the public other than designated health workers.

The DGHS referred to the advisory on the use of homemade protective cover for face and mouth available on the website of the Ministry of Health.

It is to bring to your knowledge that the use of valved respirator N-95 masks is detrimental to the measures adopted for preventing the spread of coronavirus as it 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,” DGHS Rajiv Garg said in the letter.

The government had in April issued an advisory on the use of homemade protective cover for face and mouth, asking people to wear it, particularly when they step out of their residences.

The advisory stressed such face covers must be washed and cleaned each day, as instructed, and stated that any used cotton cloth could be used to make this face cover.

The colour of the fabric does not matter, but one must ensure that the material is washed well in boiling water for five minutes and dried well before making the face cover. Adding salt to this water is recommended, it said.

There are a plethora of videos available on the Internet about how to use a mask and dispose of. As per the Indian Council of Medical Research (ICMR), you must wash your hands with soap and water for at least 20 minutes before wearing a mask. In case you do have access to soap, you can use alcohol-based sanitiser. Ensure, your face mask fits appropriately and covers your nose, mouth and chin. Do not touch your mask while you are wearing it.

The death count due to the disease rose to 27,497 with 681 fatalities reported in one day.

The ministry data updated at 8 am on Monday showed that a record single-day jump of 40,425 COVID-19 cases had taken the total number of cases to 11,18,043.
