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."

Beijing, Mar 21: China reported no domestically transmitted coronavirus cases for the third consecutive day even as seven more fatalities have been confirmed, taking the death toll in the country to 3255.

No new domestically transmitted cases of COVID-19 were reported on the Chinese mainland for the third day in a row on Friday, China's National Health Commission (NHC) said on Saturday.

The overall confirmed cases on the mainland had reached 81,008 by the end of Friday, which included 3,255 who died, 6,013 patients still undergoing treatment, 71,740 patients who had been discharged after recovery, the NHC said.

The NHC said 41 new confirmed COVID-19 cases were reported on the Chinese mainland on Friday from the people arriving from abroad, taking the total number of imported cases to 269.

Madrid, Feb 23: Lionel Messi scored four goals and Barcelona reclaimed the top spot in the La Liga as Real Madrid suffered a surprise defeat by Levante last night, a week before the Clasico.

Madrid's nightmare afternoon was made worse by another injury to Eden Hazard, who was forced off in the second half of their 1-0 defeat in Valencia and is now doubtful to face Manchester City on Wednesday in the Champions League.

"It doesn't look good," said Real coach Zinedine Zidane afterwards.

Messi, meanwhile, ridiculed talk of a goal drought by scoring four against Eibar after four games without one, while emergency signing Martin Braithwaite made two assists off the bench, teeing up Messi and then Arthur Melo in injury-time.

Their 5-0 rout, coupled with Madrid's defeat, means Barca move back to the summit of La Liga, two points ahead of Zidane's side ahead of next Saturday's showdown at the Santiago Bernabeu.

It amounts to a considerable shift in momentum, with Barcelona away at Napoli in the first leg of the Champions League last 16 on Tuesday.

Madrid host City a day later and the plan had been for Hazard to regain form and fitness in what was only his second start since returning from three months out with a broken right foot.

But the Belgian sat in the dug-out with an ice pack around the same foot after going off and Zidane suggested it was a repeat injury after the match. "It can be weak where you've had an injury," he said.

For Madrid, playing catch-up again next weekend will be a particularly heavy psychological blow, especially given the series of off-field problems engulfing Barcelona in recent weeks.

Yet on the pitch, Messi showed no sign of distraction as the 32-year-old completed the second fastest of his now 36 league hat-tricks, after less than 40 minutes at Camp Nou.

"There's nothing left to do but stand up and applaud," Eibar wrote on Twitter afterwards.

"I won't wash my kit after hugging Messi," said Braithwaite.

Braithwaite's arrival from Leganes drew criticism after Barcelona capitalised on a curious La Liga rule that allows clubs to sign outside of the transfer window if they have lost a player to serious injury.

Brilliant Messi

Messi quickly got to work, scoring a brilliant first goal in the 14th minute after collecting the ball centrally, around 30 yards out. He had three Eibar defenders in front of him but found a way through, nutmegging Anaitz Arbilla before chipping delicately into the corner.

The second came in the 37th minute as Sergio Busquets found Arturo Vidal, who feathered a flick into Messi's path. Messi surged forward, past his stumbling opponents, and fired in.

His third, three minutes later, was the simplest of the trio and arrived only after he tried to play in Antoine Griezmann. His generosity was rewarded as a sloppy Griezmann touch meant the ball cannoned back to Messi, who apologetically poked in.

Coach Quique Setien was able to take Griezmann off with 18 minutes left and introduce Braithwaite for his debut. Braithwaite's first contribution was a skewed cross but things improved immeasurably from there, as two passes across goal gave Messi his fourth and Arthur his first.

Madrid were never in control of a chaotic contest against Levante but might have taken the lead if Hazard had done better with a long ball over the top from Marcelo, which he failed to control and then scuffed into the hands of Aitor Fernandez.

He limped off and Madrid lost their way, finally punished with 11 minutes left by a straight ball through to Morales. Luka Modric, exposed on the right side of Madrid's defence, was unable to recover and Morales caught Courtois by surprise by firing early past the goalkeeper and into the top corner.
