COVID-19 spreads even before people show symptoms, study says

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, Jul 7: The US House of Representatives Judiciary Committee will grill the CEOs of US tech giants Apple, Google, Facebook and Amazon during an antitrust hearing on July 27.

Apple's Tim Cook, Facebook's Mark Zuckerberg, Alphabet's Sundar Pichai and Amazon's Jeff Bezos will testify before the antitrust panel that is working on proposals to reform and regulate the digital market.

The hearing would mark the first time all four top executives testify together in front of Congress, virtually or in-person depending on the panel's call in the COVID-19 pandemic times.

"Since last June, the Subcommittee has been investigating the dominance of a small number of digital platforms and the adequacy of existing antitrust laws and enforcement," House Judiciary Committee Chairman Jerrold Nadler (D-NY) and Antitrust Subcommittee Chairman David Cicilline (D-RI) said in a statement on Monday.

"Given the central role these corporations play in the lives of the American people, it is critical that their CEOs are forthcoming. As we have said from the start, their testimony is essential for us to complete this investigation.”

The House Judiciary Committee announced its antitrust probe into the four tech giants in June last year.

Last month, the committee sent letters to technology giants Apple, Facebook, Amazon and Alphabet (Google's parent company), asking them to confirm if their chief executives will testify as part of the committee's tech competition investigation.

Committee chair David Cicilline said the documents that the investigators sought were "essential" to the probe and that requests like this were part of the "appropriate process" to obtain them.

"The only CEO who has expressed reservation about appearing, through a representative, has been Amazon," Cicilline said. "No one in this country is above the law ... nobody is above answering a congressional subpoena".

The lawmakers want the tech giants to furnish documents that have been produced in relation to other competition probes and internal communications.

The letters that the committee sent also posed questions related to possible harms to competition in the market.

In addition to the antitrust probe, Apple's App Store policies are also facing scrutiny from the US Department of Justice.

The President of United States Donald Trump has said that countries like India and China would have much more coronavirus cases than America if they conduct more tests.

“I say to my people every time we test; you find cases because we do more testing. If we have more cases, if we wanted to do testing in China or in India or other places, I promise you there would be more cases you are doing a fantastic job in getting out the swabs,” the US president said on Friday.

Trump said that the US has carried out 20 million tests while compared to America, Germany is at four million and much talked about South Korea is about three million tests. He made the remarks at Puritan Medical Products in Maine, according to Johns Hopkins Coronavirus Resource Center.

The US has reported nearly 1.9 million cases and over 1,09,000 deaths while the total number of coronavirus cases in India and China stand at 2,36,184 and 84,177 respectively, according to Johns Hopkins Coronavirus Resource Center data.

India has so far conducted over 4 million COVID-19 tests, according to the health ministry.

Trump said, “we will be well over 20 million tests. Remember this, when you test more, you have more cases.”

“Puritan is one of the only manufacturers in the world producing high-quality medical swabs that are crucial for rapid testing. And every swab you make at Puritan is proudly stamped with the beautiful phrase made in the USA,” Trump said.

“Thanks to the testing capacity that you are making possible, our country is reopening and our economy is recovering like nobody would’ve thought possible,” he added.

Trump also spoke about the huge unemployment problem the country is currently facing. He said that the economy is now back on track, referring to the latest monthly employment numbers,.

“We absolutely shattered expectations, and this is the largest monthly jobs increase in American history, think of that; that’s a long time,” Trump said

“I think it’s more than double or about double of what our highest was before so this is the largest monthly job increase in American history. And we’re going to have a phenomenal next year. We’re going to have a tremendous couple of months prior to the election on November 3 very, very important date,” the president said.

Keeping an eye on the November 3 presidential elections, Trump is seeking re-election for his second consecutive term. He is pitted against Democratic presidential nominee Joe Biden who in opinion polls is surging several points of Trump.

“It’s going to be a very important election because the only thing that can screw it up is if you get the wrong president and they raise your taxes, and they open up your borders so that everybody pours into our country,” Trump said.

Trump also vowed to bring the American economy back on track, which has been badly hit by the coronavirus pandemic. He reiterated that his administration has built a strong economy in the last three years.

Describing the fight against coronavirus as the greatest national and industrial mobilisation since the World War II, Trump said that his administration has marshaled the full power of the US government and US industry to defeat the invisible enemy.

“It is indeed an enemy. It came from China, should have been stopped in China. They didn’t do that,” he alleged.

The administration, he said, has delivered over 1.5 billion pieces of personal protective equipment to doctors and nurses on the front lines. We slashed the red tape to speed up the development of vaccines.

“And vaccines are coming along incredibly well, wait till you see, and therapeutics. And we partnered at private sector leaders such as Puritan to build the largest and most advanced testing capacity on the face of the earth, like this one,” the US president said.

The Puritan factory in Maine, he said, quickly ramped up the production to produce nearly 20 million foam-tipped swabs each month.

“Then in April, my administration invoked the Defence Production Act to help you scale up even more. Under a USD 75 million public-private partnership, Puritan will soon double production to 40 million swabs per month,” Trump added.

Wellington, Jun 8: New Zealand lifted all domestic coronavirus restrictions on Monday after its final COVID-19 patient was given the all clear, with Prime Minister Jacinda Ardern revealing she danced around her living room when told about the milestone.

While strict border controls will remain in place, Ardern said restrictions such as social distancing and limits on public gatherings were no longer needed.

"We are confident we have eliminated transmission of the virus in New Zealand for now," she said in a televised address, saying Kiwis had "united in unprecedented ways to crush the virus".

The South Pacific nation, with a population of five million, has had 1,154 confirmed COVID-19 cases and 22 deaths.

There have been no new infections for 17 days and, until Monday, just one active case for more than a week.

Details of the final patient were not released for privacy reasons but it is believed to be a woman aged in her 50s who was linked to a cluster at an Auckland nursing home.

Ardern said the sacrifices made by New Zealanders, including a drastic seven-week lockdown that helped curb infection rates, had been rewarded now that there were no active cases in the country.

Asked about her reaction upon hearing the news, she replied: "I did a little dance" with baby daughter Neve.

"She was caught a little by surprise but she joined in, having absolutely no idea why I was dancing around the lounge."

New Zealand's move down to Level 1, the lowest rating on its four-tier virus response system, means nightclubs can operate without dance floor restrictions and theatres will reopen.

It also means sporting events can proceed with crowds in the stands, a change New Zealand Rugby (NZR) said offered its Super Rugby Aotearoa competition the opportunity to achieve a world first when it kicks off this weekend.

"We're incredibly proud, and grateful, to be the first professional sports competition in the world to be in a position to have our teams play in front of their fans again," NZR chief executive Mark Robinson said.

While many other sporting competitions around the globe have announced plans to restart, the vast majority will be played either with no crowds or with numbers severely restricted.

On a broader level, Ardern said easing restrictions would help New Zealand's economy.

"We now have a head start on economic recovery because at level one we become one of the most open, if not the most open, economies in the world," she said.

The prime minister said modelling showed the economy would operate at just 3.8 percent below normal at Level 1, compared with a 37 percent impairment at Level 4 lockdown.
