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.

Apr 29: US President Donald Trump doubled down on China for failing to tame the coronavirus at its very origin, saying it has led to 184 countries "going through hell", as several American lawmakers demanded steps to reduce dependence on Beijing for manufacturing and minerals.

Trump has been publicly blaming China for the global spread of the "invisible enemy" and launched an investigation against it. He has also indicated that the US may be looking at "a lot more money" in damages from China than the USD 140 billion being sought by Germany from Beijing for the pandemic.

Leaders of the US, the UK and Germany believe that the deaths and the destruction of the global economy could have been avoided, had China shared the information about the virus in its early phases.

"It's in 184 countries, as you hear me say often. It's hard to believe. It's inconceivable," Trump told reporters at White House Tuesday. "It should have been stopped at the source, which was China. It should have been stopped very much at the source, but it wasn't. And now we have 184 countries going through hell.”

The virus, which originated in China's Wuhan city in mid-November, has killed more than two lakh people and infected over three million globally. The largest number of them are in the US: nearly 59,000 deaths and over one million infections.

The massive outbreak in the US has put Trump under increasing pressure from American lawmakers to decrease US dependence on Beijing and they have also sought compensation from China.

Senator Ted Cruz and his colleagues have urged Defence Secretary Mark Esper and Interior Secretary David Bernhardt to support the development of a fully domestic supply chain of rare earths and other minerals that are critical for manufacturing defence technologies and supporting national security.

“It is clear that our dependence on China for vital rare earths threatens our US manufacturing and defence-industrial base. As the October 2018 Defence Industrial Base Report states: ‘China represents a significant and growing risk to the supply of materials deemed strategic and critical to US national security.' [...] Ensuring a US supply of domestically sourced rare earths will reduce our vulnerability to supply disruptions that poses a grave risk to our military readiness," the Senators wrote.

The US is 100 percent import-dependent for rare earths as well as 13 other metals and minerals on the US Government Critical Minerals List and more than 75 percent import reliant for an additional 10 minerals.

Congressman Brian Mast on Tuesday introduced a legislation to hold China accountable for its "coronavirus deception". The resolution would empower the US to withhold payments on debts owed to China equal to the costs incurred by the US in response to COVID-19.

“China's total lack of transparency and mishandling of the coronavirus outbreak has cost tens of thousands of lives, millions of jobs and left untold economic destruction. Congress must hold China accountable for their cover-up and force them to pay back the taxpayer dollars that have been spent as a result,” Mast said.

Cruz, member of the Senate Foreign Relations Committee, announced his intention to introduce a legislation to cut off Hollywood studios from assistance they receive from the Department of Defence if those studios censor their films for screening in China.

This legislation is part of Sen. Cruz's comprehensive push to combat China's growing influence over what Americans see and hear, which includes legislation targeting information warfare from the Chinese Communist Party across higher education, sports, films, radio broadcasts, and more.

Indian-American Congressman Ami Bera and Congressman Ted S. Yoho, both members of the House Foreign Affairs Committee, will lead a bipartisan virtual Special Order to highlight the importance of US global leadership during the COVID-19 pandemic.

“If we abdicate our place as a leader in global health, there is another country eager to take the reins. China has not been subtle in asserting itself on global health issues, and often not for the benefit of other nations. China's recent coronavirus debacle should be evidence enough that their communist regime cannot be trusted to lead with accountability, transparency, or pragmatism, traits that are essential when fighting widespread disease,” Yoho said.

“As for how China would fare as a global health leader, look no further than the disastrous initial response by the WHO to coronavirus, one that was clearly influenced by Beijing. Information was slow-walked, warnings from nations like Taiwan were ignored at crucial turning points, and cooperation with outside health experts was spurned until it was too late. And it has resulted in the largest public health disaster the world has seen in over a century,” he said.

In an interview to Fox News, Senator Marco Rubio alleged that if China had acted when those warnings were being made, instead of silencing the people that were talking about it, they could have limited the spread.

“So there was no doubt that that was a deliberate decision made on their part. The one way to hold them accountable is to do what we should be doing anyway. That is moving the means of production to become less and less dependent upon them. What you're going to see after this pandemic is that more and more countries are going to prioritize their healthcare manufacturing capabilities and other industries,” he said.

Washington, Jun 18: US Defence officials are concerned over China's use of COVID-19 situation to gain stakes in strategically important companies of United States as the impact of novel coronavirus has left several companies in dire need of capital.

Amid the pandemic, it getting hard for the defence department to keep an eye on national security and help protect smaller companies down the chain, CNN reported.

"We are paying close attention to any indicators that China is leveraging Covid-19 to take advantage of a situation where defence companies need capital more than ever," a defence official told CNN.

In April, Ellen Lord, undersecretary of defence for acquisition and sustainment said it is paying close attention to 'adversaries' against the 'economic warfare' with the United States.

"We have to be very, very careful about the focused efforts some of our adversaries have to really undergo sort of economic warfare with us, which has been going on for some time," Ellen Lord, undersecretary of defence for acquisition and sustainment was quoted as saying by CNN.

US Committee on Foreign Investment protects its interest against hostile countries gaining ownership in strategically important companies. But the pandemic is changing the definition of national security concerns to include drugs, protective gear and medical supplies.

"These are now national security needs and we probably should have been thinking about it a long time ago in terms of biowarfare that we should have a trusted industrial base or a set of trusted allies -- the UK, or NATO allies or Japan or Korea -- who are trusted in that regard," Bill Greenwalt, a former Pentagon official.

Give the threat posed by foreign acquisition, Pentagon has been offering tools to help small US businesses defend themselves against adversarial investment and conducting background checks with other government agencies to ensure transparency.

US President Donald Trump's trade adviser Peter Navarro recently told CNN if Trump wins reelection, Washington DC will likely take offshore supply chains as national security priorities.

"If we fail to do that in the face of this crisis, we will have failed this country and all future generations of Americans," Navarro said.

The US State Department has also warned US allies to "avoid economic overreliance on China" and "guard their critical infrastructure" from China's influence.

Chad P Bown, a senior fellow at the Peterson Institute for International Economics, pointed to recent China's economic coercion of Australia on the political matter saying, "this is how China operates and everybody knows it."

Washington, May 29: US President Donald Trump while speaking with reporters at the White House on Thursday said that he is more liked in India than the media in his own country --the United States.

"I know. And they like me in India. I think they like me in India certainly more than the media likes me in this country, " Trump told reporters at his Oval office.

"And I like Modi (Prime Minister Narendra Modi). I like your prime minister a lot. He's a great gentleman. A great gentleman," he added further while briefing the reporters.

But when asked over ties between India and China, the US President said, "They have a big conflict going with India and China. Two countries with 1.4 billion people. Two countries with very powerful militaries. And India is not happy, and probably China is not happy."

Reiterating his offer to mediate between India and China on the border issue, Trump said that he spoke to Prime Minister Narendra Modi, who is not in "good mood" about the ongoing situation with Beijing.

However, informed sources from the Ministry of External Affairs told ANI on Friday that there has been no recent contact between Prime Minister Modi and the US President. The last conversation between them took place on April 4, 2020, on the subject of hydroxychloroquine.

Asked about his Wednesday's tweet regarding his offer to mediate between India and China, Trump said, "I would do that. If they (China and India) thought it would help." However, Trump did not clarify when did he speak to Modi.

Trump on Wednesday tweeted that he is "ready, willing and able to mediate" between India and China."We have informed both India and China that the United States is ready, willing and able to mediate or arbitrate their now raging border dispute," the US President said.

In response to Trump's mediation offer, India said on Thursday that it is engaged with the Chinese side to resolve the border issue peacefully.

India's Ministry of External Affairs spokesperson Anurag Srivastava said that the two sides have established mechanisms both at military and diplomatic levels to resolve situations that may arise in border areas peacefully through dialogue and "continue to remain engaged through these channels."

Indian and Chinese field commanders have been holding talks on de-escalating the tensions.

China has also struck a conciliatory tone on the border issue with India, saying the two countries pose no threat to each other and should resolve their differences through communication, while not allowing them to overshadow bilateral relations.

"We should never let differences overshadow our relations. We should resolve differences through communication. China and India should be good neighbours of harmonious coexistence and good partners to move forward hand in hand," said Chinese Ambassador to India, Sun Weidong, on Wednesday.

The tensions escalated between India and China following a number of confrontations between soldiers of both armies.

Troops of India and China were engaged in two face-offs in Eastern Ladakh and North Sikkim along the disputed Line of Actual Control (LAC), where troops from both sides suffered injuries early this month.

Studies over the anti-malarial drug, which is believed to cure the highly contagious coronavirus, have shown side-effects, according to the Centers for Disease Control and Prevention and the World Health Organisation. But Trump continues to defend his decision to take hydroxychloroquine saying he believes that it gives an additional level of safety.
