Washington, Apr 2: The total US death toll from the coronavirus pandemic topped 4,000 early Wednesday, more than double the number from three days earlier, according to a tally by Johns Hopkins University.

The number of deaths was 4,076 -- more than twice the 2,010 recorded late Saturday.

More than 40 percent of recorded deaths nationally were in New York state, the Johns Hopkins data showed.

On Tuesday the United States exceeded the number of deaths in China, where the pandemic emerged in December before spreading worldwide.

The number of confirmed US cases has reached 189,510, the most in the world, though Italy and Spain have recorded more fatalities.

After initially downplaying the threat from new coronavirus in the early stages of the US outbreak, President Donald Trump warned of "a very, very painful two weeks" to come for the country on Tuesday.

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."

Washington, Jan 12: The US State Department has described the recent visit of envoys of 15 countries to Jammu and Kashmir as an "important step" but expressed concern over the continued detention of political leaders and restrictions on internet in the region.

Alice Wells, the Acting Assistant Secretary of State for South Asia, tweeted on Saturday that she was "closely following" the visit of the envoys to Kashmir, describing it an "important step".

Wells, who will be visiting India this week, added: "We remain concerned by detention of political leaders and residents and Internet restrictions. We look forward to a return to normalcy."

The group of diplomats made a two-day visit to the Union Territory on Thursday and Friday to see the conditions thereafter Jammu and Kashmir's special constitutional status was removed last August.

While some US politicians and media have criticised the action by Prime Minister Narendra Modi's government, the US has officially appeared to support the abrogation of the Constitution's Article 370 on the special status.

Last October, Wells told the House of Representatives Subcommittee on Asia and the Pacific that the State Department supported the objectives behind it, while not directly mentioning the abrogation.

"The Indian government has argued that its decision on Article 370 was driven by a desire to increase economic development, reduce corruption, and uniformly apply all national laws in Jammu and Kashmir, particularly in regard to women and minorities.

"While we support these objectives, the Department remains concerned about the situation in the Kashmir Valley, where daily life for the nearly eight million residents has been severely impacted since August 5," she had said.

Washington has banked on India's democratic institutions - the judiciary and public debates - being able to steer the country.

Bearing this out, the Supreme Court last week ordered the government to review its decision to shut down the internet in Kashmir, which it declared was a fundamental right, thus taking a step to address Wells's concern.
