Modi govt to lend $1 billion for Adani Australia coal mine

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.

Islamabad, Jun 6: Pakistan has reported a record 97 COVID-19 deaths in a single day, taking the total number of fatalities to 1,935, while the number of confirmed cases in the country approached 94,000 after over 4,700 infections were detected, the health ministry said on Saturday.

Punjab registered 35,308 COVID-19 cases, Sindh 34,889, Khyber-Pakhtunkhwa 12,459, Balochistan 5,776 Islamabad 4,323, Gilgit-Baltistan 897 and Pakistan-occupied Kashmir 331 cases, the Ministry of National Health Services said.

The total number of COVID-19 cases reached 93,983 after 4,734 new infections were detected across the country, it said.

With a record 97 fatalities in one day, the death toll in the country has reached 1,935, while 32,581 people have recovered from the disease.

The ministry said that the total number of active COVID-19 cases in Pakistan are 59,467, out of which 1,265 patients are in critical condition.

More than 100 labs in the country have so far conducted 660,508 tests, including 22,185 in the last 24 hours.

There are 747 hospitals across the country with COVID-19 treatment facilities where 5,060 patients are being treated. Others have been asked to self-isolate at home.

Hundreds of thousands of people across the world are joining the anti-racism demonstrations days after the killing of George Floyd in United Sates. 

The protests are being held in cities including London, Manchester, Cardiff, Leicester and Sheffield.

Demonstrators attached ropes to the statue of Edward Colston before pulling it down to cheers and roars of approval from the crowd. Images on social media show the statue was eventually rolled into the city's harbour. 

It was not the only statue targeted on Sunday. In Brussels, protesters clambered onto the statue of former King Leopold II and chanted "reparations".

The word "shame" was also graffitied on the monument, reference perhaps to the fact that Leopold is said to have reigned over the mass death of 10 million Congolese.

In London, thousands of people congregated around the US embassy for the second day running.

While protests were mainly peaceful, there were some scuffles near the office of Prime Minister Boris Johnson and outside the Parliament gates.

In Hong Kong, about 20 people staged a rally in solidarity with the Black Lives Matter movement on Sunday outside the US consulate in the semi-autonomous Chinese city.

"It's a global issue," Quinland Anderson, a 28-year-old British citizen living in Hong Kong, told The Associated Press news agency.

"We have to remind ourselves despite all we see going on in the US and in the other parts of the world, Black lives do indeed matter."

Several dozen demonstrators took part in a Black Lives Matter protest held in Tel Aviv's central Rabin Square.

A rally in Rome's sprawling People's Square was noisy but peaceful, with the majority of protesters wearing masks to protect against coronavirus. Participants listened to speeches and held up handmade placards saying "Black Lives Matter" and "It's a White Problem".

In Spain, several thousand people gathered on the streets of Barcelona and at the US embassy in Madrid.

Many in Madrid carried homemade signs reading "Black Lives Matter", "Human rights for all" and "Silence is pro-racist".

"We are not only doing this for our brother George Floyd," said Thimbo Samb, a spokesman for the group that organised the events in Spain mainly through social media. "Here in Europe, in Spain, where we live, we work, we sleep and pay taxes, we also suffer racism."
