Azaan from mosques causes noise pollution: Tripura governor

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.

New Delhi, June 16: Tensions along the Line of Control border between India and China have spiked with an Indian army officer and two soldiers killed in the Galwan area of Ladakh, the Indian army said in a statement on Tuesday.

This is the first time in decades that a clash involving casualties has taken place on the 3,488 kilometre border between India and China.

"During the de-escalation process underway in the Galwan Valley, a violent face-off took place yesterday night with casualties. The loss of lives on the Indian side includes an officer and two soldiers. Senior military officials of the two sides are currently meeting at the venue to defuse the situation," said an official statement.

The two sides had made headway in talks last week with army chief General MM Naravane saying disengagement was in progress. The development had come after weeks of tension, including an incident in which patrolling soldiers from the two sides came to blows on the banks of Pangong Lake, resulting in injuries.

The two armies have since thinned out some forces in a positive signal but soldiers, tanks and other armoured carriers remained heavily deployed in the high-altitude region, an official had said.

India and China fought a brief border war in 1962 and have not been able to settle their border despite two decades of talks. Both claim thousands of kilometres of territory and patrols along the undemarcated Line of Actual Control - the de-facto border - often run into each other, leading to tensions.
