Wuhan buses hit road after two-month lockdown

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.

Jul 1: Hong Kong police moved swiftly on Wednesday against protesters gearing up for the first rally since the introduction of sweeping security legislation, making their first arrest under it and warning of punishment for pro-independence material.

Beijing on Tuesday unveiled the details of the much-anticipated law after weeks of uncertainty, pushing China's freest city and one of the world's most glittering financial hubs onto a more authoritarian path.

As hundreds of protesters gathered downtown for an annual rally marking the 23rd anniversary of the former British colony's handover to China, riot police used pepper spray to arrest at least two people, while one metro station closed.

Police, who earlier banned the rally, cited the law for the first time in confronting protesters and they also made their first arrest under it - a man holding a flag advocating independence.

"You are displaying flags or banners/chanting slogans/or conducting yourselves with an intent such as secession or subversion, which may constitute offences under the ... national security law," police said in a message displayed on a purple banner.

The law will punish crimes of secession, subversion, terrorism and collusion with foreign forces with up to life in prison, heralding a more authoritarian era for the Asian financial hub.

China's parliament adopted it in response to months of pro-democracy protests last year triggered by fears that Beijing was stifling the city's freedoms, guaranteed by a "one country, two systems" formula agreed when it returned to Chinese rule.

Authorities in Beijing and Hong Kong have repeatedly said the legislation is aimed at a few "troublemakers" and will not affect rights and freedoms, nor investor interests.

But critics fear it will crush the freedoms that are seen as key to Hong Kong's success as a financial centre.

"With the release of the full detail of the law, it should be clear to those in any doubt that this is not the Hong Kong they grew up in," said Hasnain Malik, head of equity research, Tellimer in Dubai.

"The difference is that U.S. and China relations are far worse and this could be used as a pretext to impede the role of Hong Kong as a finance hub."

In Beijing, Zhang Xiaoming, executive deputy director of Beijing's Hong Kong and Macau Affairs Office, told reporters suspects arrested by Beijing's new security office in Hong Kong could be tried on the mainland.

He said the mainland's national security office abided by Chinese law and that Hong Kong's legal system could not be expected to implement the laws of the mainland. Article 55 of the law states that Beijing's national security office in Hong Kong could exercise jurisdiction over "complex" or "serious" cases.

Mainland security agencies will also be based in Hong Kong officially for the first time, with powers that go beyond city laws.

"The law is a birthday gift to (Hong Kong) and will show its precious value in the future," Zhang said, adding the law would not be applied retroactively.

On July 1 last year, hundreds of protesters stormed and vandalised the city's legislature to protest against a now-scrapped bill that would have allowed extraditions to mainland China.

Those protests evolved into calls for greater democracy, paralysing parts of the city and paving the way for Beijing's imposition of the law this week.

'INEVITABLE'

Speaking at a flag-raising ceremony to mark the handover anniversary, the city's Beijing-backed leader, Carrie Lam, said the law was the most important development since the city's return to Chinese rule.

"It is also an inevitable and prompt decision to restore stability," Lam said at the same harbour-front venue where 23 years ago the last colonial governor, Chris Patten, a staunch critic of the security law, tearfully handed back Hong Kong to Chinese rule.

Some pro-Beijing officials and political commentators say the law is aimed at sealing Hong Kong's "second return" to the motherland after the first failed to bring residents to heel.

Luo Huining, the head of Beijing's top representative office in Hong Kong, said at the ceremony the law was a "common aspiration" of Hong Kong citizens.

Critics denounced the lack of transparency surrounding the details of the legislation until it was unveiled. It came into force at 11 p.m. (1500 GMT) on Tuesday.

Some pro-democracy activists gave up membership of their groups just before the law came into force, though calling for the campaign for democracy to go on offshore.

"I saw this morning there are celebrations for Hong Kong's handover, but to me it is a funeral, a funeral for 'one country two systems'," said democracy lawmaker Kwok Ka-ki.

Washington, Mar 28: The world is in the face of a devastating impact due to the coronavirus pandemic and has clearly entered a recession, the International Monetary Fund said on Friday, but projected a recovery next year.

"We have reassessed the prospects for growth for 2020 and 2021. It is now clear that we have entered a recession as bad or worse than in 2009. We do project recovery in 2021," IMF Managing Director Kristalina Georgieva told reporters at a news conference.

Georgieva was addressing the press after a meeting of governing body of the IMF, the International Monetary and Financial Committee. Representing 189 members, the body met virtually to discuss the unprecedented challenge posed to the world by COVID-19.

The key to recovery in 2021, she said, is only if the international community succeeds in containing the virus everywhere and prevent liquidity problems from becoming a solvency issue.

"The US is in recession, as is the rest of the advanced economies of the world. And in a big chunk of developed and emerging markets in developing economies. How severe? We are working now on our projections for 2020, Georgieva said in response to a question.

The new projections are expected in the next few weeks.

Stressing that while containment is the main reason for the economy to stand still and get into a recession, she said containment is very necessary to come out of this period and step in to recovery. "Until the virus is not contained, it would be very difficult to go to the lives we love."

"A key concern about a long-lasting impact of the sudden stop of the world economy is the risk of a wave of bankruptcies and layoffs that not only can undermine the recovery. But can erode the fabric of our societies," the IMF chief said.

To avoid this from happening, many countries have taken far-reaching measures to address the health crisis and to cushion its impact on the economy, both on the monetary and on the fiscal side, she said.

The IMF chief said 81 emergency financing requests, including 50 from lower-income countries, have been received. She said current estimate for the overall financial needs of emerging markets is 2.5 trillion dollars.

"We believe this is on the lower end. We do know that their own reserves and domestic resources will not be sufficient," she added.

The G-20, a day earlier, reported fiscal measures totalling some 5 trillion dollars or over 6 per cent of the global GDP.

Responding to another question, Georgieva said the IMF is projecting recession for 2020.

"We do expect it to be quite deep and we are very much urging countries to step up containment measures aggressively so we can shorten the duration of this period of time when the economy is in standstill," she said.

"And also to apply well-targeted measures, primarily focusing on the health system to absorb that enormous stress that comes from coronavirus. And on people, businesses and the financial system, I am very pleased to say that when we went through countries' responses, that sense of targeted fiscal measures is there and are also very impressive to see the size of these measures," she added.

"Countries are doing all they can on the fiscal and on the monetary front. We have heard from our members' very impressive decisions taken over the last days," the IMF chief said.

"We also want to caution that as we are responding now, we want to make the recession as possibly short and not too deep. We also want to think about what is going to follow the recovery and make sure that we are putting forward measures that can be supportive in this regard," she said.
