Jun 13: Requiring the wearing of masks to prevent the spread of the novel coronavirus in areas at the epicenter of the global pandemic may have prevented tens of thousands of infections, a new study suggests.

Mask-wearing is even more important for preventing the virus' spread and the sometimes deadly COVID-19 illness it causes than social distancing and stay-at-home orders, researchers said, in the study published in PNAS: The Proceedings of the National Academy of Sciences of the USA.

Infection trends shifted dramatically when mask-wearing rules were implemented on April 6 in northern Italy and April 17 in New York City - at the time among the hardest hit areas of the world by the health crisis - the study found.

"This protective measure alone significantly reduced the number of infections, that is, by over 78,000 in Italy from April 6 to May 9 and over 66,000 in New York City from April 17 to May 9," researchers calculated.

When mask-wearing went into effect in New York, the daily new infection rate fell by about 3% per day, researchers said. In the rest of the country, daily new infections continued to increase.

Direct contact precautions - social distancing, quarantine and isolation, and hand sanitizing - were all in place before mask-wearing rules went into effect in Italy and New York City. But they only help minimize virus transmission by direct contact, while face covering helps prevent airborne transmission, the researchers say.

"The unique function of face covering to block atomization and inhalation of virus-bearing aerosols accounts for the significantly reduced infections," they said. That would indicate "that airborne transmission of COVID-19 represents the dominant route for infection."

The U.S. Center for Disease Control and Prevention on Friday urged organizers of large gatherings that involve "shouting, chanting or singing to strongly encourage the use of cloth face coverings to lower the risk of spreading the coronavirus."

New Delhi, June 22: Former Prime Minister Manmohan Singh on Monday asked Prime Minister Narendra Modi to be “mindful of the implication of his words” as a controversy raged over his “no intrusion” remark about the violent face-off with Chinese troops in the Galwan Valley.

“The Prime Minister must always be mindful of the implications of his words and declarations on our Nation’s security as also strategic and territorial interests,” Singh said in a statement here as Chinese media welcomed Modi’s ‘no intrusion’  remarks contending that it may lead to a de-escalation of tensions between China and India.

Congress has been maintaining that Modi’s assertions at Friday’s all-party meeting that neither was there any intrusion nor was any Indian post captured ran counter to the statements made by the Indian Army and the External Affairs Ministry.

Singh said the prime minister cannot allow his words to be used by China as a vindication of its position and all organs of the government should work together to tackle this crisis and prevent it from escalating further.

“We remind the Government that disinformation is no substitute for diplomacy or decisive leadership. The truth cannot be suppressed by having pliant allies spout comforting but false statements,” the former prime minister said.

Singh said the prime minister and the government should rise to the occasion to ensure justice for Colonel B Santosh and the army jawans who made the supreme sacrifice and resolutely defended the nation’s territorial integrity.

“To do any less would be a historic betrayal of the people’s faith,” the former prime minister said.

“At this moment, we stand at historic crossroads. Our Government’s decisions and actions will have serious bearings on how the future generations perceive us,” Singh said.

Singh said China was brazenly and illegally seeking to claim parts of Indian territory such as the Galwan Valley and the Pangong Tso Lake by committing multiple incursions between April 2020 till date.  

“We cannot and will not be cowed down by threats and intimidation nor permit a compromise with our territorial integrity,” said Singh. 

The former prime minister said this was a moment where “we must stand together as a nation and be united in our response to this brazen threat.”
