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:  Around 5,000 people have signed up for the phase I clinical trial of recombinant novel coronavirus vaccine in Chinese city Wuhan where the virus first emerged late last year.

The recruitment for participants ended this week with nearly 5,000 volunteers signing up for the trial, state-run Beijing News reported on Wednesday.

A single-centre, open and dose-escalation phase I clinical trial for recombinant novel coronavirus vaccine (adenoviral vector) will be tested in healthy adults aged between 18 and 60 years, according to the ChiCTR (China Clinical Trial Register).

The trial, led by experts from the Academy of Military Medical Sciences, gained its approval on March 16 and the research is expected to last half a year.

Requiring at least 108 participants, the trial will be conducted in Wuhan, capital of Hubei province, the region worst-affected by the virus in the country, state-run China Daily reported.

Participants will experience 14-day quarantine restrictions after being vaccinated and their health condition will be recorded every day.

Chinese scientists are hastening the development of COVID-19 vaccines through five approaches --- inactivated vaccines, genetic engineering subunit vaccines, adenovirus vector vaccines, nucleic acid vaccines and vaccines using attenuated influenza virus as vectors.

So far, most teams are expected to complete preclinical research in April and some are moving forward faster, Wang Junzhi, an academician with the Chinese Academy of Engineering said.

Wang noted that research and development of COVID-19 vaccines in China is not slower than foreign counterparts and has been carried out in a scientific, standardised and orderly way.

China has stepped up the process to finalise vaccines to counter COVID-19 after Kaiser Permanente research facility in Seattle and Washington stole the march and began human trials.

China lifted tough restrictions on the Hubei province on Wednesday after a months-long lockdown as the country reported no new domestic cases.

But there were another 47 imported infections from overseas, the National Health Commission said. In total, 474 imported infections have been diagnosed in China -- mostly Chinese nationals returning home.

Islamabad, Jul 20: Six advisors of Pakistan Prime Minister Imran Khan posses dual citizenships and several of top 20 aides have admitted of owning movable and immovable assets worth millions of dollars abroad.

The list was published on the official website of Pakistan government's cabinet division.
All the dual nationals were working as special assistants to the prime minister (SAPM). 

These people include SAPM on Overseas Pakistanis Syed Zulfiqar Abbas Bukhari (UK), SAPM on Power Division Shahzad Qasim (US), SAPM on Petroleum Nadeem Babar (US), SAPM on Political Affairs Shahbaz Gill (US), SAPM on Parliamentary Coordination Nadeem Afzal Gondal (Canada) and SAPM on Digital Pakistan Tania Aidrus (Canadian citizenship by birth).

According to Gulf News report, the wealthiest SAPM is Power Division and Mineral Resources Assistant Shahzad Syed Qasim who has assets worth over Rs 4 billion followed by SAPM on Petroleum Nadeem Babar with assets worth Rs 2.75 billion. Meanwhile, Adviser for Overseas Pakistanis Syed Zulfiqar Abbas Bukhari's net assets is estimated over Rs 2 billion.

Giving further details of the wealthiest SAPM, the official website stated that the PM's aide on Power Division and Coordination of Marketing and Development of Mineral Resources owns assets in Pakistan, UAE and US. His three properties in UAE include two villas in Jumeirah Golf Estates and Sienna Lakes, Jumeirah Golf Estates and an apartment at Park Towers, DIFC - all worth Dh20,688,000. He has three cars in the UAE worth Dh400,000 and in the US, he has property worth US$865,000 while he has Rs 4 billion in various local and foreign bank accounts and retirement funds including $2.1 million in US.

Meanwhile, Nadeem Babbar, who is Special Assistant on Petroleum Division, owns assets worth over Rs 2.7 billion, including several properties in Pakistan and abroad and stakes in more than 30 local and foreign companies.

The Gulf News further reported that in the list Dr Moeed Yusuf's, Special Assistant to the Prime Minister on National Security Division and Strategic Policy Planning, the name was also included but was later withdrawn as it was clarified that he had the US residency and only holds the citizenship of Pakistan as per the affidavit submitted to the government. "I have not returned to the US since I took up my current responsibility, have no employment or income in the US nor do I have any millions worth properties abroad" Dr Yusuf was quoted as saying.

The latest list on PM Imran Khan's advisors possessing dual nationalities has sparked strong criticisms by the Opposition leaders.
