Will have to take military way if India doesn't listen, warns China

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.

Canberra, May 21: Australian Prime Minister Scott Morrison and his Indian counterpart, Narendra Modi, are looking forward to deepening the countries' strategic relationship, with both sides expected to sign a range of pacts from defence to trade in strategic sectors amid heightened tensions with China over Beijing's response to coronavirus pandemic.

During a virtual summit, scheduled to take place on June 4, both leaders are expected to ramp up efforts to diversify Australia's export markets and find trusted suppliers of vital products and components, a local newspaper, The Australian reported on Tuesday.

The new agreements will focus on reliable supply chains in key strategic sectors, including medical goods, technology and critical minerals, amid heightened tensions with China over Beijing's response to coronavirus pandemic.

The leaders will seal a new defence agreement allowing reciprocal access to bases and co-operation on military technology projects, while a new education partnership will be on the table to help overcome Australian university reliance on Chinese students.

The talks in terms of strategic convergence, now have greater significance as COVID-19 exacerbates the strategic contest between the US and China, and forces like-minded countries to seek out reliable partners.

Australian farmers could also benefit, with talks underway on expanding agricultural exports to India, including barley, as China throws up new trade barriers, media reports stated.

The virtual summit follows the cancellation of Morrison's planned state visit to India in January due to the bushfires.

Morrison said last year, ahead of his planned visit, that India was "a natural partner for Australia", referring to the countries' "shared values" -- a point of differentiation with China.

Former Department of Foreign Affairs and Trade secretary Peter Varghese, who wrote a landmark report on the bilateral relationship in 2018, was quoted by the newspaper as saying that India would be even more important to Australia in the post-COVID world. "If one of the lessons from COVID is that countries need to spread their risk, then finding new markets or building up existing markets is a crucial part of that," he added.

Varghese noted that India, a member of the Quadrilateral Security Dialogue along with Australia, Japan and the US, was a vital strategic partner to Australia in helping "constrain China's ambitions to be the predominant power".

"That shared objective between Australia and India of not wanting to see the region dominated by China is a key component of building up our geopolitical relationship," he told The Australian.

The summit also follows recent talks between Australian Foreign Minister Marise Payne and Indian counterpart Subrahmanyam Jaishankar on the pandemic response and Australia's call for an independent inquiry, which was overwhelmingly backed at the World Health Assembly on Tuesday.

Australia wants to support India to develop a domestic critical minerals processing industry, which would provide Western nations with an alternative to sourcing the materials from China.

Meanwhile, India has strong expertise as a manufacturer of drugs and medical equipment, while Australia is a centre of biomedical research, opening the possibility for closer co-operation in the key sector, the media reported further.

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.
