40 militant groups were operating in Pakistan: Imran Khan

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."

Jaipur, Mar 11: A 85-year-old man in Jaipur, who had returned from Dubai on February 28, has tested positive for coronavirus, a state government official said on Wednesday.

He was found presumptive positive in the first test on Tuesday and hence, a second test was conducted with fresh samples, the reports of which arrived late Tuesday night, Additional Chief Secretary, Medical and Health, Rohit Kumar Singh, said.

“The man who travelled to Dubai has been tested positive for coronavirus. It has been confirmed now,” Singh said.

“We have also got the manifest of the Spicejet flight he took from Dubai to Jaipur and are doing due diligence on that,” the official said, adding that intense contact tracing was underway.

The man has been kept in isolation at the SMS Hospital here.

“The man came to the hospital on Monday with symptoms of the virus. After the first test, his wife and son too have been kept in isolation at the hospital. The two, however, do not have coronavirus affliction symptoms,” Singh said.

A total of 235 people who came in contact with the octogenarian and his family have already been traced and are being monitored, he said.

Other contacts are also being traced, Singh added.

An Italian couple, who tested positive for COVID-19 last week, are also admitted in the hospital but their condition is improving, he said.
