Wuhan woman with no symptoms infects five relatives with coronavirus: Scientists

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.

Melbourne, July 1: Authorities will lock down around 300,000 people in suburbs north of Melbourne for a month from late on Wednesday to contain the risk of infection after two weeks of double-digit rises in new coronavirus cases in Australia's second-most populous state.

Australia has fared better than many countries in the pandemic, with around 7,830 cases and 104 deaths, but the recent surge has stoked fears of a second wave of COVID-19, echoing concerns expressed in other countries.

Globally, coronavirus cases exceeded 10 million on Sunday, a major milestone in the spread of a disease that has killed more than half a million people in seven months.

From midnight, more than 30 suburbs in Australia's second-biggest city will return to stage three restrictions, the third-strictest level in curbs to control the pandemic. That means residents will be confined to home except for grocery shopping, health appointments, work or caregiving, and exercise.

The restrictions will be accompanied by a testing blitz that authorities hope will extend to half the population of the area affected, and for which borders will be patrolled, authorities said. The measures come as curbs ease across the rest of the state of Victoria, with restaurants, gyms and cinemas reopening in recent weeks.

Victoria recorded 73 fresh cases on Tuesday from 20,682 tests, following an increase of 75 cases on Monday. State premier Daniel Andrews warned on Wednesday that the return of broader restrictions across city remained a possibility.

"If we all stick together these next four weeks, we can regain control of that community transmission ... across metropolitan Melbourne," Andrews said at a briefing. "Ultimately if I didn't shut down those postcodes I'd be shutting down all postcodes. We want to avoid that."

Victoria's spike in cases has been linked to staff members at hotels housing returned travellers for which quarantine protocols were not strictly followed. Victorian state authorities have announced an investigation into the matter.

Some other Australian states and territories are preparing to open borders, but applying limits and quarantine measures to citizens of Victoria as the school holiday season gets under way.

South Australia, the country's fifth most populous state, has had just three new cases in the past month. But citing the spike in coronavirus infections, on Tuesday it cancelled its scheduled reopening to other parts of the nation.

New South Wales (NSW), Australia's most populous state, has stopped short of closing its borders to all Victorians, but those holidaying from hotspot areas - not permitted under NSW rules - can be handed a fine of A$11,000 ($7,596) or jailed if they are detected, state authorities said.

The delays reopening internal borders cast doubts over a federal plan to set up "travel bubble" with neighbouring New Zealand that would allow movement between the two countries.

New Delhi, Jan 10: One woman reported a rape every 15 minutes on average in India in 2018, according to government data released on Thursday, underlining its dismal reputation as one of the worst places in the world to be female.

The highly publicised gang rape and murder of a woman in a bus in New Delhi in 2012 brought tens of thousands onto the streets across India and spurred demands for action from film stars and politicians, leading to harsher punishments and new fast-track courts. But the violence has continued unabated.

Women reported almost 34,000 rapes in 2018, barely changed from the year before. Just over 85% led to charges, and 27% to convictions, according to the annual crime report released by the Ministry of Home Affairs.

Women's rights groups say crimes against women are often taken less seriously, and investigated by police lacking insensitivity.

"The country is still run by men, one (female prime minister) Indira Gandhi is not going to change things. Most judges are still men," said Lalitha Kumaramangalam, former chief of the National Commission for Women.

"There are very few forensic labs in the country, and fast-track courts have very few judges," said Kumaramangalam, a member of Prime Minister Narendra Modi's Bharatiya Janata Party (BJP).

The rape of a teenager in 2017 by former BJP state legislator Kuldeep Singh Sengar gained national attention when the accuser tried to kill herself the following year, accusing the police of inaction.

Five months before Sengar was convicted last December, the accuser's family had to be provided with security after a truck crashed into the car she was in, injuring her and killing two of her relatives.

A 2015 study by the Centre for Law & Policy Research in Bengaluru found that fast-track courts were indeed quicker, but did not handle a high volume of cases.

And a study in 2016 by Partners for Law in Development in New Delhi found that they still took an average of 8.5 months per case - more than four times the recommended period.

The government statistics understate the number of rapes as it is still considered a taboo to report rape in some parts of India and because rapes that end in the murder are counted purely as murders.
