Italy floods: Death toll climbs to 29

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.

Beijing, Jan 24: As China stepped up measures to control the spread of coronavirus, locking down Wuhan and Huanggang cities in the Hubei province where several Indians live, the Indian Embassy here has set up hotlines for their assistance.

Chinese officials assured all assistance, including food supply, to the Indians who stayed put in the province, the Indian Embassy here said in a press release on Thursday.

Wuhan and its surrounding area became the epicentre of the coronavirus outbreak as the confirmed cases climbed to over 600 mostly from the city and the province with 17 deaths so far.

China has virtually sealed Wuhan and Huanggang cities, halting all public transport, including flight services, and advised people to stay at home and follow the precautions. The two cities put together have a population of over 17 million people.

Chinese officials said the measures have been taken to prevent the spread of the virus to other cities and the world.

Concerns arose for India too as about 700 Indian students, mostly studying medicine in different Chinese universities, resided in Wuhan and its neighbouring areas.

While many of them were believed to have left home for the Chinese New Year holidays, others remained in the city to complete their academic work. However, the exact number is not yet known.

“The Embassy of India has been receiving queries from Indians in Hubei province as well as their relatives in India in connection with the evolving situation of coronavirus infection in China,” the embassy press release said.

The embassy is in touch with relevant Chinese authorities in Beijing and Wuhan as well as Indians in Hubei Province, especially in Wuhan, it said.

“We are closely monitoring the evolving situation in China, including the advisories issued by the World Health Organisation (WHO),” the embassy said.

According to the embassy, Chinese authorities have assured all assistance to residents of Wuhan, including food supply.

“At present, it is reported that supermarkets (particularly those that are government-run) and e-commerce services, including food delivery, continue to remain operational in Wuhan,” it said.

The embassy has started two hotlines for those who wish to get in touch with the Mission in this regard in the following phone numbers:              +8618612083629 and +8618612083617.

“All are advised to also keep track of the embassy's social media accounts (Twitter:@EoIBeijing; Facebook: India in China) for updates on this evolving situation,” the release said.

Meanwhile, the Chinese Foreign ministry said all assistance would be provided to consular officials of the foreign missions to ensure the safety of the foreigners in the country.

Asked whether China would consider any request from the respective countries to move their citizens out of Wuhan, Chinese Foreign Ministry spokesman Geng Shuang said, “We always help foreign consular officials in China in their official jobs, we offer them all the assistance and convenience necessary and we work to guarantee foreign citizens' legitimate rights and interest in China.”

He said while specific detailed would be provided by local officials, China in principle, has always handled issues according to domestic laws, international laws and bilateral consular agreements.

Jul 3: China under President Xi Jinping has stepped up its "aggressive" foreign policy toward India and "resisted" efforts to clarify the Line of Actual Control that prevented a lasting peace from being realised, according to a report released by a US Congress appointed commission.

The armies of India and China have been locked in a bitter standoff at multiple locations in eastern Ladakh for the last seven weeks, and the tension escalated after 20 Indian soldiers were killed in a violent clash in the Galwan Valley on June 15.

“Under General Secretary of the Chinese Communist Party (CCP) Xi Jinping, Beijing has stepped up its aggressive foreign policy toward New Delhi. Since 2013, China has engaged in five major altercations with India along the Line of Actual Control (LAC),” said a brief issued by US-China Economic and Security Review Commission.

"Beijing and New Delhi have signed a series of agreements and committed to confidence-building measures to stabilise their border, but China has resisted efforts to clarify the LAC, preventing a lasting peace from being realised,” said the report and was prepared at the request of the Commission to support its deliberations.

Authored by Will Green, a Policy Analyst on the Security and Foreign Affairs Team at the Commission, the report says that the Chinese government is particularly fearful of India’s growing relationship with the United States and its allies and partners.

“The latest border clash is part of a broader pattern in which Beijing seeks to warn New Delhi against aligning with Washington,” it said.

After Xi assumed power in 2012, there was a significant increase in clashes, despite the fact that he met Prime Minister Narendra Modi several times and Beijing and New Delhi have agreed to a series of confidence-building mechanisms designed to mitigate tensions.

Prior to 2013, the last major border clash was in 1987. The 1950s and 1960s were a particularly tense period, culminating in 1962 with a war that left thousands of soldiers dead on both sides, according to the records of China's People's Liberation Army, the report said.

“The 2020 skirmish is in line with Beijing’s increasingly assertive foreign policy. The clash came as Beijing was aggressively pressing its other expansive sovereignty claims in the Indo-Pacific region, such as over Taiwan and in the South and East China seas,” it said.

China is engaged in hotly contested territorial disputes in both the South China Sea and the East China Sea. Beijing has built up and militarised many of the islands and reefs it controls in the region. Both areas are stated to be rich in minerals, oil and other natural resources and are vital to global trade.

China claims almost all of the South China Sea. Vietnam, the Philippines, Malaysia, Brunei and Taiwan have counter claims over the area.

Several weeks before the clash in the Galwan Valley, Chinese Defence Minister Wei Fenghe called on Beijing to “use fighting to promote stability” as the country’s external security environment worsened, a potential indication of China’s intent to proactively initiate military tensions with its neighbours to project an image of strength, the report said.
