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."

Mangaluru, Jun 3: Cyclone Nisarga did not land in Karnataka and has passed its border with heavy rains and strong winds, said an official on Wednesday.

However rains continued to lash parts of coastal Karnataka. There was no report of any casualty, the official added.

"It has already passed. We have not got any reports of fatalities. A heavy rain was expected and the deputy commissioners were alerted. Fishermen too were warned," said Karnataka State Disaster Management Authority (KSDMA) Principal Secretary T K Anil Kumar.

Kumar said Nisarga's actual landing is in Maharashtra and the warning was given for that state and Gujarat.

"In the fringe proportion (of Karnataka), high winds were expected and fishermen were warned not to venture into the sea," he said.

Kumar said the department interacted with the deputy commissioners of Belagavi, Uttara Kannada, Udupi, Dakshina Kannada, Chikkamagaluru and Shivamogga and alerted them about heavy rains.

Karnataka State Natural Disaster Monitoring Centre Director Srinivas Reddy said the department has kept four National Disaster Relief Force (NDRF) teams on standby in Mangaluru and Kodagu for any eventuality.

The teams have been mobilized from Guntur in Andhra Pradesh.

"More rain is predicted in coastal districts. Wind speed too will be more in coastal areas," said Reddy.

According to a Met Department official, the track of Nisarga is expected to be 200-400km off Karnataka coast.

"Sudden wind speed had been reported along the coast. We had issued port warnings," said the official.
