Taj is 2nd best UNESCO world heritage site: survey

The government suspended all the India-bound air travel from China and has declared all visas 'invalid', on Monday, due to the rapid escalation of cases of novel coronavirus outbreak which originated in Wuhan.

"Embassy and our Consulates have been receiving several queries from Chinese citizens as well as other foreign nationals, who are based out of China or visited China in the last 2 weeks, as to whether they can use their valid single/multiple entry visas to travel to India," tweeted the Embassy of India in Beijing, China.

"It is clarified that existing visas are no longer valid. Intending visitors to India should contact the Indian Embassy in Beijing ([email protected]) or the Consulates in Shanghai ([email protected]) and Guangzhou ([email protected]) to apply afresh for an Indian visa," it said.

Further, regarding the validity of visas, the embassy said, "Indian Visa Application Centres (http://blsindia-china.com) in these cities may also be contacted in this regard. Visa Section of the Embassy/Consulates of India in China can be contacted to ascertain the validity of visa before undertaking any visit to India."

"All those who are already in India (with regular or e-visa) and had traveled from China after January 15 are requested to contact the hotline number of Ministry of Health and Family Welfare of Government of India (+91-11-23978046 and email: [email protected])," the embassy said.

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.

Washington, Jan 12: US president Donald Trump said Saturday the United States was monitoring Iranian demonstrations closely, warning against any new “massacre” as protests broke out after Tehran admitted to shooting down a passenger plane.

Iran said earlier it unintentionally downed a Ukrainian jetliner outside Tehran, killing all 176 people aboard, in an abrupt about-turn after initially saying that it had crashed due to mechanical failure. The firing came shortly after Iran launched missiles at bases in Iraq housing American forces.

President Hassan Rouhani said a military probe into the tragedy had found that “missiles fired due to human error” brought down the Boeing 737, calling it an “unforgivable mistake.”

Trump told Iranians -- in tweets in both English and Farsi -- that he stands by them and is monitoring the demonstrations.

“To the brave, long-suffering people of Iran: I've stood with you since the beginning of my Presidency, and my Administration will continue to stand with you,” he tweeted.

“There can not be another massacre of peaceful protesters, nor an internet shutdown. The world is watching,” he added, apparently referring to an Iranian crackdown on street protests that broke out in November.

“We are following your protests closely, and are inspired by your courage," he said.

The new demonstrations follow an Iranian crackdown on street protests that broke out in November. Amnesty International has said it left more than 300 people dead. Internet access was reportedly cut off in multiple Iranian provinces ahead of memorials planned a month after the protests.

On Saturday evening, police dispersed students who had converged on Amir Kabir University in Tehran to pay tribute to the victims, after some among the hundreds gathered shouted "destructive" slogans, Fars news agency said.

State television reported that students shouted "anti-regime" chants, while the news agency Fars reported that posters of Soleimani had been torn down.
