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.

Sydney, Mar 29: Steve Smith's two-year leadership ban ended quietly Sunday, leaving him eligible again to captain Australia at a time of uncertainty over when international cricket will resume.

Smith was stripped of the captaincy and banned from leading Australia for two years over his involvement in the 2018 ball tampering scandal in South Africa. His sentence ended Sunday and he can again captain Australia if called upon.

Australian players were due this week to conclude a series of matches in New Zealand and, for some, to join the Indian Premier League. But it wasn't clear Sunday if the IPL will take place this year and when international matches will resume. Australia's scheduled mid-year tours to England and Bangladesh are in doubt.

Smith told Channel Nine television's Sports Sunday he is doing his best to stay mentally and physically fit, training in his home gym, going on 10 kilometer (6 mile) runs and practising the guitar.

"It's obviously not looking likely (the IPL will go ahead) at the moment," Smith said. "I think there might be some meetings over the next few days to discuss what the go is with it all.

"I'm just trying to stay physically and mentally fit and fresh and, if it goes ahead at some point, then great. And if not, there's plenty going on in the world at the moment. So just play it day by day."

It seems unlikely Smith will return to the captaincy when cricket resumes. Tim Paine is firmly established as Australia's test captain and at 35 is not immediately considering retirement. Aaron Finch has captained Australia successfully in white ball cricket.

The conclusion of Smith's ban ends the period of upheaval in Australian cricket that followed the ball tampering incident in the second test at Cape Town in 2018 when Cameron Bancroft, with the knowledge of Smith and his vice-captain David Warner, used sandpaper to change the condition of the ball.

Smith and Warner received one-year bans from international and most domestic cricket and Bancroft was banned for nine months. The scandal also resulted in the resignation of coach Darren Lehmann and the departure of Cricket Australia's chief executive, James Sutherland.

Warner remains under a career-long leadership ban.
