As US snubs high-tech visas, Indians head to Canada

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."

Riyadh, Mar 6: Saudi Arabia on Thursday emptied Islam's holiest site for sterilisation over fears of the new coronavirus, an unprecedented shutdown state media said will last while the year-round Umrah pilgrimage is suspended.

The kingdom halted the pilgrimage for its own citizens and residents on Wednesday, on top of restrictions announced last week on foreign pilgrims to stop the disease from spreading.

State television relayed images of an empty white-tiled area surrounding the Kaaba -- a large black cube structure inside Mecca's Grand Mosque -- which is usually packed with tens of thousands of pilgrims.

As a "precautionary measure", the area will remain closed as long as the umrah suspension lasts but prayers will be allowed inside the mosque, state-run Saudi Press Agency cited a mosque official as saying.

Additionally, the Grand Mosque and the Prophet's Mosque in the city of Medina will be closed an hour after the evening "Isha" prayer and will reopen an hour before the dawn "Fajr" prayer to allow cleaning and sterilisation, the official added.

A group of cleaners was seen scrubbing and mopping the tiles around the Kaaba, a structure draped in gold-embroidered gold cloth towards which Muslims around the world pray.

A Saudi official told news agency the decision to close the area was "unprecedented".

On Wednesday, Saudi Arabia suspended the umrah for its own citizens and residents over fears of the coronavirus spreading to Islam's holiest cities.

The move came after authorities last week suspended visas for the umrah and barred citizens from the six-nation Gulf Cooperation Council from entering Mecca and Medina.

Saudi Arabia on Thursday declared three new coronavirus cases, bringing the total number of reported infections to five.

The umrah, which refers to the Islamic pilgrimage to Mecca that can be undertaken at any time of year, attracts millions of Muslims from across the globe annually.

The decision to suspend the umrah mirrors a precautionary approach across the Gulf to cancel mass gatherings from concerts to sporting events.

It comes ahead of the holy fasting month of Ramadan starting in late April, which is a favoured period for pilgrimage.

It is unclear how the coronavirus will affect the hajj, due to start in late July.

Some 2.5 million faithful travelled to Saudi Arabia from across the world in 2019 to take part in the hajj, which is one of the five pillars of Islam as Muslim obligations are known.

The event is a massive logistical challenge for Saudi authorities, with colossal crowds cramming into relatively small holy sites, making attendees vulnerable to contagion.

Already reeling from slumping oil prices, the kingdom risks losing billions of dollars annually from religious tourism as it tightens access to the sites.

New Delhi, Jan 4: In more troubles for the former Finance Minister and senior Congress leader P Chidambaram, the Enforcement Directorate (ED) on Friday questioned him for over six hours in its probe into the Air India aircraft deal case, first time since his release from Tihar jail almost a month ago.

A senior ED official told IANS, "We questioned Chidambaram for over six hours today in the ongoing probe into the Air India deal with Airbus."

According to financial probe agency officials, Air India had planned to buy over 111 aircraft from Airbus and Boeing during the erstwhile United Progressive Alliance (UPA) government in 2009. This is the first time the ED has questioned the senior Congress leader in the Air India deal case.

The questioning of Chidambaram came for the first time since his release from the Tihar jail where he spent 106 days in connection with the INX Media money laundering case. He was released from Tihar on December 4 last year after he was granted bail by the Supreme Court. The former finance minister is also being investigated by the ED in a separate money-laundering cases of Aircel-Maxis deal.

An ED official said the contract to buy 43 aircraft from Airbus was finalised by a panel of ministers headed by Chidambaram in 2009. According to the ED, when the proposal to buy 43 aircraft from Airbus was sent to the Cabinet Committee on Security (CCS), there was a condition that the aircraft manufacturer would have to build training facilities and MRO (Maintenance, Repair and Overhaul) centres at a cost of Rs 70,000 crore. But later, when the purchase order was placed, the clause was removed.

The name of another UPA minister, Praful Patel, had also come up in the alleged scam in a charge sheet filed by the ED against corporate lobbyist Deepak Talwar on March 30 last year. Talwar was arrested last year by the ED after he was deported from the UAE.

The ED is probing the Air India-Indian Airlines merger; purchase of 111 aircraft from Boeing and Airbus at Rs 70,000 crore; ceding profitable routes and schedules to private airlines, and opening of training institutes with foreign investment.
