US to participate in Iranian probe of Ukrainian plane crash

Houston, Mar 15: Researchers, studying the novel coronavirus, have found that the time between cases in a chain of transmission is less than a week, and over 10 per cent of patients are infected by someone who has the virus, but does not show symptoms yet, a finding that may help public health officials contain the pandemic.

The study, published in the journal Emerging Infectious Diseases, estimated what's called the serial interval of the coronavirus by measuring the time it takes for symptoms to appear in two people with the virus -- the person who infects another, and the infected second person.

According to the researchers, including those from the University of Texas at Austin, the average serial interval for the novel coronavirus in China was approximately four days.

They said the speed of an epidemic depends on two things -- how many people each case infects, and how long it takes cases to spread.

The first quantity, the scientists said, is called the reproduction number, and the second is the serial interval.

Due to the short serial interval of the disease caused by the coronavirus -- COVID-19 -- they said, emerging outbreaks will grow quickly, and could be difficult to stop.

“Ebola, with a serial interval of several weeks, is much easier to contain than influenza, with a serial interval of only a few days,” said Lauren Ancel Meyers, study co-author from UT Austin.

Meyers explained that public health responders to Ebola outbreaks have much more time to identify and isolate cases before they infect others.

“The data suggest that this coronavirus may spread like the flu. That means we need to move quickly and aggressively to curb the emerging threat,” Meyers added.

In the study, the scientists examined more than 450 infection case reports from 93 cities in China, and found the strongest evidence yet that people without symptoms must be transmitting the virus -- known as pre-symptomatic transmission.

More than one in ten infections were from people who had the virus but did not yet feel sick, the scientists said.

While researchers across the globe had some uncertainty until now about asymptomatic transmission with the coronavirus, the new evidence could provide guidance to public health officials on how to contain the spread of the disease.

“This provides evidence that extensive control measures including isolation, quarantine, school closures, travel restrictions and cancellation of mass gatherings may be warranted,” Meyers said.

The researchers cautioned that asymptomatic transmission makes containment more difficult.

With hundreds of new cases emerging around the world every day, the scientists said, the data may offer a different picture over time.

They said infection case reports are based on people's memories of where they went and whom they had contact with, and if health officials move quickly to isolate patients, that may also skew the data.

“Our findings are corroborated by instances of silent transmission and rising case counts in hundreds of cities worldwide. This tells us that COVID-19 outbreaks can be elusive and require extreme measures,” Meyers said.

Tehran, Feb 28: The coronavirus epidemic in Iran has cost 26 lives, the health ministry announced Thursday, with a vice president becoming the latest top official to be infected as the spread appeared to accelerate.

Health ministry spokesman Kianoush Jahanpour told a news conference that the tally of infections had risen to 245 with 106 more cases confirmed -- the highest number for a single day since Iran announced its first infections on February 19.

The Islamic republic has the highest death toll from the virus outside China, where COVID-19 first emerged.

Among the latest coronavirus sufferers is one of Iran's seven vice presidents, Massoumeh Ebtekar, who oversees women's affairs.

Ebtekar, a former spokeswoman for students who took 52 Americans hostage at the US embassy in Tehran in 1979, is being treated at home and members of her team have been tested, state news agency IRNA reported.

Mojtaba Zolnour, head of parliament's national security and foreign affairs committee, also contracted the virus, appearing in a video posted by Fars news agency saying he was in self-quarantine.

The cleric is a deputy for the Shiite holy city of Qom in central Iran where the country's first cases were detected.

According to media reports, among the deceased in Qom on Thursday was theologian Hadi Khroroshahi, who in 1981 was named Iran's first ambassador to the Vatican.

The announcement by Zolnour comes two days after another top official, deputy health minister Iraj Harirchi, head of the government's coronavirus task force, said he too had contracted the virus.

On Wednesday, Iranian authorities announced domestic travel restrictions for people with confirmed or suspected infections.

They also placed curbs on access to major Shiite pilgrimage sites, including the Imam Reza shrine in second city Mashhad and the Fatima Masumeh shrine in Qom.

Visitors to the shrines will be allowed to visit on condition they are provided "with hand-washing liquids, proper (health) information, masks", Health Minister Saeed Namaki said.

They must "not gather together in groups but just pray and leave", he said.

In a rare move, authorities announced the cancellation of the main Friday weekly prayers in Tehran, Qom and Mashhad as well as in the capitals of 22 of Iran's 31 provinces and other infected areas.

"All of these decisions are temporary and if the situation changes, we might intensify or ease them," Namaki said.

Feb 26: Looking out over the world’s largest cricket stadium, the seats jammed with more than 100,000 people, India’s prime minister heaped praise on his American visitor.

“The leadership of President Trump has served humanity,” Prime Minister Narendra Modi said Monday, highlighting Trump’s fight against terrorism and calling his 36-hour visit to India a watershed in India-U.S. relations.

The crowds cheered. Trump beamed.

“The ties between India and the U.S. are no longer just any other partnership,” Modi said. “It is a far greater and closer relationship.”

India, it seems, loves Donald Trump. It seemed obvious from the thousands who turned out to wave as his motorcade snaked through the city of Ahmedabad, and from the tens of thousands who filled the city’s new stadium. It seemed obvious from the hug that Modi gave Trump after he descended from Air Force One, and from the hundreds of billboards proclaiming Trump’s visit.

But it’s not so simple.

Because while Trump is genuinely popular in India, his clamorous and carefully choreographed welcome was also about Asian geopolitics, China’s growing power and a masterful Indian politician who gave his American visitor exactly what he wanted.

Modi “is doing this not necessarily because he loves Trump,” said Tanvi Madan, the director of the India Project at the Brookings Institution in Washington, D.C. “It’s very much about Trump as the leader of the U.S. and recognizing what it is that Trump himself likes.”

Trump likes crowds — big crowds — and the foot soldiers of India’s political parties have long known how to corral enough people to make any politician look popular. In a city like Ahmedabad, the capital of Modi’s home state of Gujarat and the center of his power base, it wouldn’t take much effort to fill a cavernous sports stadium. It was more surprising that a handful of seats remained empty, and that some in the stands had left even before Trump had finished his speech.

For India, good relations with the U.S. are deeply important: They signal that India is a serious global player, an issue that has long been important to New Delhi, and help cement an alliance that both nations see as a counterweight to China’s rise.

“For both countries, their biggest rival is China,” said John Echeverri-Gent, a professor at the University of Virginia whose research often focuses on India. “China is rapidly expanding its presence in the Indian Ocean, which India has long considered its backyard and its exclusive realm for security concerns.”

“It’s very clearly a major concern for both India and the United States,” he said.

Trump isn’t the first U.S. president that Modi has courted. In 2015, then-President Barack Obama was the first American chief guest at India’s Republic Day parade, a powerful symbolic gesture. Obama also got a Modi hug, and the media in both countries were soon writing about the two leaders’ “bromance.”

Trump is popular in India, even if some of that is simply because he’s the U.S. president. A 2019 Pew Research Center poll showed that 56% of Indians had confidence in Trump’s abilities in world affairs, one of only a handful of countries where he has that level of approval. But Obama was also popular: Before he left office, he had 58% approval in world affairs among Indians.

The Pew poll also indicated that Trump’s support was higher among supporters of Modi’s Hindu nationalist party.

That’s not surprising. Both men have fired up their nationalist bases with anti-Muslim rhetoric and government policies, from Trump’s travel bans to Modi’s crackdown in Kashmir, India’s only Muslim-majority state.

And Trump’s Indian support is far from universal. Protests against his trip roiled cities from New Delhi to Hyderabad to the far northeastern city of Gauhati, although those demonstrations were mostly overshadowed by protests over a new Indian citizenship law that Modi backs.

Modi, who is widely popular in India, has faced weeks of protests over the law, which provides fast track naturalization for some foreign-born religious minorities — but not Muslims. While Trump talked about ties with India on Tuesday, Hindus and Muslims fought in violent clashes that left at least 10 people dead over two days.

In some ways, Modi and Trump are powerful echoes of each other.

They have overlapping political styles. Both are populists who see themselves as brash, rule-breaking outsiders who disdain their countries’ traditional elites. Both are seen by their critics as having authoritarian leanings. Both surround themselves with officials who rarely question their decisions.

But are they friends?

Trump says yes. “Really, we feel very strongly about each other,” he said at a New Delhi press briefing.

But many observers aren’t so sure.

“The question is how much of this is real chemistry, as opposed to what I’d call planned chemistry” orchestrated for diplomatic reasons, said Madan. “It’s so hard to know if you’re not in the room.”

Certainly, Modi understands America’s importance to India. While the two countries continue to bicker about trade issues, the prime minister organized a welcome that impressed even India’s news media, which have watched countless choreographed mass political rallies.

“There is no other country for whose leader India would hold such an event, and for which an Indian prime minister would lavish such rhetoric,” the Hindustan Times said in an editorial.

“The spectacle and the sound were worth a thousand agreements.”
