Muslim girls allegedly forced to remove scarves for II PU exam at Canara College

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, June 1: The private bus services resumed services in Dakshina Kannada and Udupi districts today with 15 per cent hike in the fares. For 70 days these buses were stayed off the roads as lockdown was imposed in the region on March 22 in the wake of covid-19 outbreak.

Buses were sanitised in the morning. The bus operators have decided to operate only a few of the buses initially.

Of the about 2,000 service buses (inter-district buses and long-route buses within the district) of private operators in Dakshina Kannada and Udupi, only 25% resumed services. Only 135 out of 320 city buses in Mangaluru resumed services.

The number of passengers on board the buses were also very less in the morning. A few buses had arranged sanitisers for passengers, drivers and conductors.
