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, Apr 12: The US has overtaken Italy as the country with the highest number of deaths due to COVID-19 pandemic with the fatalities crossing 20,000, according to Johns Hopkins University data, as the novel coronavirus continues to wreak havoc across the globe.

The deadly coronavirus, that originated in China in December last year, has so far killed more than one lakh people across the globe. The United States on Saturday became the country with the highest number of deaths at 20,597, surpassing Italy's 19,468 fatalities.

More than 5.3 lakh Americans have tested positive for coronavirus, which is about the same for the next four countries put together: Spain (163,027), Italy (152,271), Germany (125,452) and France (93,790). In terms of fatalities, the US and Italy are followed by Spain (16,606), France (13832) and United Kingdom (9,875), the varsity data showed.

New York City, the financial capital of the world, has emerged as the epicenter of coronavirus in the world. A city of 8.3 million, which is one of the most densely populated cities in the US, by Saturday night had as many as 8,627 deaths and more than 180,000 people had tested positive for COVID-19.

President Donald Trump has declared a national emergency and all the 50 States have been notified with major disaster declaration. More than 95 per cent of the country's 330 million population are under stay-at-home order. Trump has deployed more than 50,000 personnel from the armed forces in fight against COVID-19.

After an initial two-week social mitigation measures, that includes social distancing, the measures have been extended till April 30. Initially, members of the White House Task Force on Coronavirus had projected between one and two lakhs deaths. Now, they have dropped the projection to 60,000 deaths, mainly due to the successful implementation of these measures.

"The people of our country have gone through a lot. But we did it the right way. And we look like we'll be coming in on the very, very low side, really below the lowest, the lowest side of the curve of death," Trump told Fox News on Saturday night.

Trump asserted that situation was improving in places like New York, where there is a drop in new patients. Responding to a question, he said he wanted the country to open up as soon as possible.

However, he has not taken a decision so far, even as some media reports said that he the President was looking for early May.

"I think it's going to be the toughest decision that I've ever made. I really, hopefully that I ever will have to make. But it's certainly the toughest decision that I've ever made. I hope that I'm going to make the right decision," Trump said, adding that he will be making a decision reasonably soon.

"We're setting up a council now of some of the most distinguished leaders in virtually every field including politics and business and medical. We'll be making that decision fairly soon," Trump said.

Meanwhile, The New York Times reported that its investigations have revealed that the president was warned about a potential pandemic but that internal divisions, lack of planning and his faith in his own instincts led to a halting response.

According to The Washington Post, coronavirus is killing about one in 10 hospitalised middle-aged patients and four in 10 older than 85 in the United States. It is particularly lethal to men even when taking into account common chronic diseases that exacerbate risk.

Globally, the novel coronavirus has killed 108,862 people and infected over 1.7 million people globally. The US has the highest number of infections at 529,887, according to Johns Hopkins University data.

The Seattle City Council, one of the most powerful city councils in the U.S., on Monday unanimously passed a resolution condemning India’s recently-enacted Citizenship Amendment Act (CAA) and the National Register of Citizens (NRC).

Reaffirming Seattle as a welcoming city and expressing solidarity with the city’s South Asian community regardless of religion and caste, the resolution “resolves that the Seattle City Council opposes the National Register of Citizens and the Citizenship Amendment Act in India, and finds these policies to be discriminatory to Muslims, oppressed castes, women, indigenous, and LGBT people“.

Introduced by Indian American City Council member Kshama Sawant, the resolution urges the Parliament of India to uphold the Indian Constitution by repealing the CAA, and to stop the National Register of Citizens, and take steps towards helping refugees by ratifying various UN treaties on refugees.

“Seattle City’s decision to condemn CAA should be a message to all who wish to undermine pluralism and religious freedom. They cannot peddle in hate and bigotry, and expect to have international acceptability at the same time,” said Ahsan Khan, president of Indian American Muslim Council.

Thenmozhi Soundararajan of Equality Labs, which organised the community in support of the resolution, welcomed its passage. “We are proud of the Seattle City Council for standing on the right side of history today. Seattle is leading the moral consensus in the global outcry against the CAA, she said.

Soundararajan said that thousands of organizers across the country have called, e-mailed, and visited Seattle City Council members to amplify this resolution, and it sets an example to cities across the United States.

“At a time when members of the Indian ruling party sided Trump, the Muslim ban, and his war on immigrants as justification for targeting hundreds of millions of Indian minorities, Americans have a unique responsibility to stand up and speak about this human rights crisis. We are glad that Seattle is leading the way on this,” she said.

Beijing, Jan 25: The death toll due to the novel coronavirus (2019-nCoV) outbreak in China has soared to 41, while the number of infected persons were 1,287, the National Health Commission said on Saturday.

The Commission said that 444 fresh cases were reported since Friday, with 237 patients in serious conditions, while 38 had been cured and discharged from hospitals, reports Efe news.

Health authorities have carried out check-ups on 15,197 people who have come into close contact with the infected persons. Nearly 14,000 of them continue to be monitored for symptoms.

The others cases outside of China were reported in France (two), Australia (one), Thailand (four including two cured), Japan (two including one cured), South Korea (two), the US (two), Vietnam (two), Singapore (three), Nepal (one), Hong Kong (five), Macao (two) and Taiwan (three).

The symptoms of the new coronavirus, provisionally designated by the World Health Organization as 2019-nCoV, are similar to those of cold but may be accompanied by fever and fatigue, dry cough and dyspnea (shortness of breath).

The WHO has so far to declared the outbreak as an international health emergency.

Strict measures were being carried out in China, which include complete suspension of transport in around a dozen cities in Hubei province and also cancelling Chinese New Year celebrations.

Traditional events at Lama Temple and Ditan Park in Beijing were cancelled due to the risk of spreading the virus, authorities reported Friday, while the famous Forbidden City has also been closed indefinitely.

Wuhan, the capital of Hubei, where the virus was first reported, has been on lockdown since Thursday to prevent further spread of the virus and the city's authorities have begun to build a "special hospital" with 1,000 beds for infected patients.

"Construction of the special hospital with a capacity of 1,000 beds for patients with #nCoV2019 has begun in Wuhan," official China Daily said on Twitter.

The hospital in Wuhan will be based on the model of a similar facility that was built in just seven days in Beijing to deal with SARS in 2003.
