Pak to buy more Malaysian palm oil to compensate for India's withdrawal

Feb 22: A 20-year-old Chinese woman from Wuhan, the epicentre of the coronavirus outbreak, travelled 400 miles(675 km) north to Anyang where she infected five relatives, without ever showing signs of infection, Chinese scientists reported on Friday, offering new evidence that the virus can be spread asymptomatically.

The case study, published in the Journal of the American Medical Association, offered clues about how the coronavirus is spreading, and suggested why it may be difficult to stop.

"Scientists have been asking if you can have this infection and not be ill? The answer is apparently, yes," said Dr. William Schaffner, an infectious disease expert at Vanderbilt University Medical Center, who was not involved in the study.

China has reported a total of 75,567 cases of the virus known as COVID-19 to the World Health Organization (WHO) including 2,239 deaths, and the virus has already spread to 26 countries and territories outside of mainland China.

Researchers have reported sporadic accounts of individuals without any symptoms spreading the virus. What's different in this study is that it offers a natural lab experiment of sorts, Schaffner said.

"You had this patient from Wuhan where the virus is, travelling to where the virus wasn't. She remained asymptomatic and infected a bunch of family members and you had a group of physicians who immediately seized on the moment and tested everyone."

According to the report by Dr Meiyun Wang of the People's Hospital of Zhengzhou University and colleagues, the woman travelled from Wuhan to Anyang on Jan. 10 and visited several relatives. When they started getting sick, doctors isolated the woman and tested her for coronavirus. Initially, the young woman tested negative for the virus, but a follow-up test was positive.

All five of her relatives developed COVID-19 pneumonia, but as of Feb. 11, the young woman still had not developed any symptoms, her chest CT remained normal and she had no fever, stomach or respiratory symptoms, such as cough or sore throat.

Scientists in the study said if the findings are replicated, "the prevention of COVID-19 infection could prove challenging."

Key questions now, Schaffner said, are how often does this kind of transmission occur and when during the asymptomatic period does a person test positive for the virus.

Italian researchers have claimed that they have successfully developed a vaccine to contain coronavirus (COVID-19) which is likely to work on humans, a report said.

Luigi Aurisicchio, CEO of Takis, the firm developing the medication, said that a coronavirus candidate vaccine has neutralised the virus in human cells for the first time, the Arab News reported.

"This is the most advanced stage of testing of a candidate vaccine created in Italy. Human tests are expected after this summer," Aurisicchio was quoted as saying to Italian news agency ANSA.

"According to the Spallanzani Hospital, as far as we know we are the first in the world so far to have demonstrated neutralisation of the coronavirus by a vaccine. We expect this to happen in humans too," he added.

The researchers experimented with the vaccine on mice that had successfully developed antibodies that blocked the virus from infecting the cells. They further observed that the five vaccine candidates generated a large number of antibodies, and selected two with the best results.

All of the vaccine candidates currently being developed are based on the genetic material of DNA protein "spike", the molecular tip used by the coronavirus to enter human cells.

They are injected with the so-called "electroporation" technique, which consists of an intramuscular injection followed by a brief electrical impulse, helping the vaccine break into the cells and activating the immune system, the report said.

Researchers believe that this makes their vaccine particularly effective for generating functional antibodies against the "spike" protein, in particular in the lung cells, which are the most vulnerable to coronavirus.

"We are working hard for a vaccine coming from Italian research, with an all-Italian and innovative technology, tested in Italy and made available to everyone," Aurisicchio was quoted by the Arab News report.

"In order to reach this goal, we need the support of national and international institutions and partners who may help us speed up the process," he noted.

The total number of COVID-19 infections, fatalities and recoveries since the pandemic began has risen to 213,013 in the country.

New Delhi, Jun 1: Actor Kendrick Sampson, who stars in HBO series Insecure, was struck by rubber bullets as Los Angeles police officers tried to disperse a crowd protesting George Floyd”s death in Minneapolis.

Floyd, a black man, died last Monday in Minneapolis, Minnesota after a white police officer pressed his knee on his neck for more than eight minutes. The officer was arrested on Friday and charged with third-degree murder.

The actor went live via Instagram on Saturday to show his view of events, but he could be also be seen on a CNN broadcast simultaneously, with viewers watching him get hit by a police baton on TV.

Sampson posted several videos on his page of a large demonstration at Pan Pacific Park near the city”s Fairfax District, where violent clashes took place throughout the day outside the Grove shopping center.

In one video, LAPD officers can be seen firing rubber bullets to try and regain control at the park.

“They shot me four times already. I already got hurt and I got hit with a baton,” Sampson said in the video on Instagram.

Another clip showed him moving away from the police, as he appeared to be hit by an officer”s baton.

“Y”all ain”t see no police f*****g up white folks when they took guns to the statehouse,” he said, referring to an incident in Michigan over coronavirus restrictions, not in California. “Y”all didn”t see police attacking white folks, beating em up with batons, shooting them with rubber bullets when they brought guns to f*****g state houses. We came up here with no weapons, with masks.… And we”re the ones who are not peaceful,” Sampson alleged.

Protests turned violent over Floyd”s death and other police killings of black people spread Saturday in dozens of US cities, with police cars set ablaze, reports of injuries mounting on all sides, shops and showrooms vandalised amid the lockdown.
