'There is no safety in Delhi,' says Supreme Court

New Delhi, Jul 21: The Centre has written to all states and union territories warning against the use of N-95 masks with valved respirator by people, saying these don't prevent the virus from spreading out and are "detrimental" to the measures adopted for its containment.

The Director-General of Health Services 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 respirator, 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 states that any used cotton cloth can be used to make this face cover. 

The colour of the fabric does not matter but one must ensure that the fabric 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.

It also listed the procedures of making such homemade masks, asking to ensure it fits the face well and there are no gaps on the sides.

It urges people to wash hands thoroughly before wearing the face cover,  switching to another fresh one as the face cover becomes damp or humid, and never reusing it after single use without cleaning it. 

"Never share the face cover with anyone. Every member in a family should have separate face cover," the advisory stated.

Lucknow, Jun 2: Bahujan Samaj Party chief Mayawati on Tuesday said protests in the US after the death of George Floyd, an African-American man, is a clear message to the world that a common man's life has value.

She said this is also guaranteed by the India Constitution, but the governments don't follow it, resulting in the current plight of migrants workers.

Floyd, a 46-year-old restaurant worker from Houston, died in Minneapolis on Monday after a white police officer pinned him to the ground. Video footage showed the officer kneeling on Floyd's neck as he gasped for breath, sparking widespread protests across the US.

"Floyd's killing by police and the 'Black lives matter' agitation in the US have given a clear message to the world that a common man's life has value and it should not be taken for granted," Mayawati said in a tweet in Hindi.

"India's constitution guarantees independence, security, self-respect and pride and governments should give special attention to it. If it was followed, crores of migrants labourers would not have to witness such bad days," she added.

She also demanded better coordination between states to check the spread of coronavirus and said Centre should intervene.

"While coronavirus patients are rising, there is lack of coordination between states and with the Centre, and allegation and counter-allegations are going on and sealing of state borders is unjustified and it is weakening the fight against the virus.  The Centre should intervene," she said in a separate tweet.

New Delhi, April 3: The Government on Thursday launched a mobile app developed in public-private partnership as part of efforts to contain the spread of coronavirus.

"The app, called 'AarogyaSetu' will enable people to assess themselves the risk for their catching the coronavirus infection," an official release said.

It said that the app will calculate this based on their interaction with others, using cutting edge Bluetooth technology, algorithms and artificial intelligence.

"Once installed in a smartphone through an easy and user-friendly process, the app detects other devices with AarogyaSetu installed that come in the proximity of that phone. The app can then calculate the risk of infection based on sophisticated parameters," the release said.

It said that the app will help the government take necessary timely steps for assessing risk of spread of COVID-19 infection and ensuring isolation where required.

"The app's design ensures privacy. The personal data collected by the app is encrypted using state-of-the-art technology and stays secure on the phone till it is needed for facilitating medical intervention," the release said.

It said the app is available in 11 languages and has highly scalable architecture.

"This app is a unique example of the nation's young talent coming together and pooling resources and efforts to respond to a global crisis. It is at once a bridge between public and private sectors, digital technology and health services delivery," the release said.
