Clouds do prevent radars from detecting accurately: Air Marshal Raghunath Nambiar

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, Jul 22: With a spike of 37,724 cases and 648 deaths reported in the last 24 hours, the total number of COVID-19 cases in India stands at 11,92,915, according to the Union Ministry of Health and Family Welfare.

The second worst-hit state, Tamil Nadu has reported 1,80,643 COVID-19 cases so far while Delhi has reported 1,25,096 cases, according to the Ministry.

Other states that have witnessed a higher number of COVID-19 positive cases include, Andhra Pradesh with 58,668 cases, Karnataka with 71,069 while Telangana has reported 47,705 COVID-19 positive cases.

Meanwhile, as per the information provided by the Indian Council of Medical Research (ICMR), the total number of samples tested up to July 21 is 1,47,24, 546 including 3,43,243 samples tested yesterday.

New Delhi, Jan 24: The Election Commission of India on Friday told the Supreme Court that its 2018 direction asking poll candidates to declare their criminal antecedents in electronic and print media has not helped curb criminalisation of politics. The poll panel suggested that instead of asking candidates to declare criminal antecedents in the media, political parties should be asked not to give tickets to candidates with criminal background.

A bench of Justices R F Nariman and S Ravindra Bhat asked the ECI to come up with a framework within one week which can help curb criminalisation of politics in nation's interest.

The top court asked the petitioner BJP leader and advocate Ashiwini Upadhyay and the poll panel to sit together and come up with suggestions which would help him in curbing criminalisation of politics.

In September 2018, a five-judge Constitution bench had unanimously held that all candidates will have to declare their criminal antecedents to the Election Commission before contesting polls and had called for a wider publicity, through print and electronic media about antecedents of candidates.
