Myanmar's Military Finds Plane Wreckage, Bodies

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.

Tehran, Jan 7: The Iranian Parliament on Tuesday ratified a motion dubbed as "harsh revenge", that considers all members of the US Pentagon and those responsible for the death of Major General Qasem Soleimani as "terrorist forces".

The triple-urgency motion is a modification of a previously ratified bill on April 23, 2019, that designated the US Central Command (CENTCOM) as a terrorist organization in retaliation to the same designation imposed on Iran's Islamic Revolutionary Guard Corps (IRGC) by Washington, the Tehran-based Mehr News Agency said in a report.

Parliament Speaker Ali Larijani said in Tuesday's open session that in the previous anti-US law, CENTCOM was designated as a terrorist entity.

"Today, following the cruel US measure in assassinating General Soleimani, the responsibility of which was accepted by the US President, we modify the previous law and announce that all members of Pentagon, commanders, agents and those responsible for the martyrdom of Gen Soleimani will be considered as terrorist forces," Larijani was quoted as saying in the report.

All of Iran nation supports the resistance, he added.

The modified law also allows withdrawal of $223 million to the IRGC's Quds Force from the National Development Fund of Iran for the next two months, added Larijani.

He said that the Supreme Leader Ayatollah Ali Khamenei's permission to withdraw the fund has been obtained, the Mehr report added.

Following its ratification, MPs chanted anti-US slogans at the Parliament.

Soleimani and his son-in-law and Abu Mahdi al-Muhandis, the second-in-command of Iraq's Popular Mobilization Front (PMF), along with eight other people were killed in the January 3 drone attack ordered by US President Donald Trump.

Soleimani, 63, was the elite Quds Force chief in charge of IRGC operations outside Iran, and has been on the ground in Syria and Iraq supervising militias backed by Tehran.

The Quds Force holds sway over a large number of militias across the region ranging from Lebanon to Syria and Iraq.

The attack has led to widespread condemnation in Iran. Supreme Leader Khamenei and President Hassan Rouhani has vowed revenge on the US.

On Sunday, Iranian MP Abolfazl Aboutorabi threatened to attack the heart of American politics.

During an open session of the Iranian Parliament on Sunday afternoon, President Trump was called a "terrorist in a suit" after he threatened to hit 52 Iranian sites hard if Tehran attacks Americans or US assets.

Wuhan, Feb 23: Ninety-seven more people died in China due to coronavirus, taking the death toll to 2,442, officials said on Sunday, as a team of WHO experts visited the worst-affected Wuhan city in Hubei province.

By the end of Saturday, a total of 2,442 people had died of the disease and 76,936 confirmed cases of novel coronavirus infection had been reported in 31 provincial-level regions, China's National Health Commission (NHC) said in its daily update on Sunday.

Ninety-six deaths were reported from Hubei province and one from Guangdong province on Saturday besides 648 new confirmed cases of coronavirus infections, it said.

Hubei province, where the virus first emerged in December last, reported 630 new confirmed cases, taking the total confirmed cases in the hard-hit province to 64,084, state-run Xinhua news agency reported.

The NHC also said China's daily number of newly cured and discharged novel coronavirus patients has surpassed that of new confirmed infections for the fifth consecutive day, indicating that cases of infections are coming down.

Saturday saw 2,230 people walk out of hospital after recovery, much higher than the number of the same day's new confirmed infections, which was 648, Xinhua reported.

A total of 22,888 patients infected with the novel coronavirus had been discharged from hospital after recovery by the end of Saturday, NHC said.

Meanwhile, a team of public health experts from the World Health Organisation (WHO) visited Wuhan on Saturday to conduct a detailed probe about the virus which reportedly originated from a seafood market in the city in December last year.

The NHC said WHO experts along with their Chinese counterparts who formed a joint investigation team have held talks with the local health authority in Wuhan and visited relevant healthcare institutions.

The UN team comprises specialists from the United States, Germany, Japan, Nigeria, Russia, Singapore and South Korea, Hong-Kong based South China Morning Post reported.

The 12-member team, which arrived in China on Monday, was initially designated to visit only Beijing, Guangdong and Sichuan provinces, while the worst-affected Hubei province and its capital Wuhan were missing from the list.

However, the team was finally given permission to visit Wuhan by the Chinese government.

Besides controlling the spread of the virus, a major task for the WHO team along with their Chinese counterparts was to come up with standard medicine to cure the disease.

The NHC said on Saturday that the team had met top Chinese respiratory disease expert Zhong Nanshan in Guangdong, and visited the centre for disease control and prevention in Guangdong and the city of Shenzhen, and Sichuan.

The specialists also discussed quarantine measures, the wild animal trade and community prevention measures with their Chinese counterparts, it said.
