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.

Jammu, Jan 15: Fresh landslides kept the Jammu-Srinagar National Highway shut for the third consecutive day on Wednesday, leaving over 5000 vehicles stranded.

"There were four fresh landslides in Digdol and Panthiyal belts on the highway in Ramban district. The traffic on the highway remained closed for the third day today", a police officer told PTI.

On Monday, heavy rains triggered shooting of stones in Moumpassi, Digdole and Panthiyal areas, forcing a suspension of the traffic, the official said.

Snowfall in Kashmir side of the highway, including Jawahar Tunnel, since Sunday has resulted in blockade of the highway.

"No fresh traffic was allowed from Nagrota in Jammu for Kashmir", he said.

As a result of the blockade of the highway, over 5000 vehicles remained stranded at various places en route from Lakhanpur in Kathua district to Banihal belt of Ramban district and also on the Kashmir side.

Sitamarhi, Jun 15: Eyewitness accounts from locals in Bihar's Sitamarhi district recount the brutality and intimidation by Nepal's security personnel who on June 12 had resorted to unprovoked firing on a group of people at the international border, which left one Indian dead and two others injured.

"18-20 shots were fired for over one hour and everyone is in shock even now," said Nitish Kumar, a resident of Jankinagar recalling the incident that took place early on Friday morning.

Nepal's Armed Police Force (APF) opened fire at the Lalbandi-Jankinagar border in which three men - Vikesh Yadav, Umesh Ram and Uday Thakur - suffered gunshot injuries. Vikash Yadav succumbed to his injuries on Friday itself.

Another person Lagan Kishore, who was at the border with his family to meet his daughter-in-law, a Nepali national and her family, said he was detained by the APF personnel who dragged him to the other side of the border.

Lagan Kishore said that the Nepali personnel abused and hit him with rifle butts and even abused his son and later resorted to firing.

Several residents of Jankinagar, who spoke to media, termed the incident as "unfortunate and shocking".

Nitish Kumar recalled: "A family was here to meet their in-laws (Nepali nationals). The daughter-in-law was talking to her family while her husband and her father-in-law sat a little distance away. Suddenly I saw Nepali personnel abusing her husband who complained about it to his father. All of a sudden the Nepali forces started thrashing them and then opened fire. They also took the father into custody."

"We were all shocked. I could hear about 18-20 gunshots fired over a period of one hour," Kumar said.

Another local, Ajit Kumar, said he was perplexed with the behaviour of the Nepali Police.

"There used to be no problems earlier. We don't understand what happened to the Nepal Police that day. The firing is unfortunate. If this continues, how will people in the border area live?" he questioned.

Ajit Kumar stated that such an incident has taken place for the first time. "People from here go to work in fields in Nepal and their people come to work in our fields. Such a thing has happened for the first time. About 80 per cent of our people are married to Nepalis," he said.

Many people who live in the adjoining districts of Bihar, which shares over 600 kilometres of border with Nepal, have relatives on either side of the border.

Meanwhile, Nepali police have claimed that Lagan Kishore, who was taken into custody following the firing by APF and handed over to Indian Security Forces at no man's land on June 13, was detained for trying to snatch a weapon from one of their personnel during an altercation.

However, both Kishore and his family have denied the claims and said he was "dragged" across the border and was beaten.

Kishore said that during the firing he had rushed towards the Indian side but Nepalese personnel hit him with rifle butt and took him to Nepal's Sangrampur. He was also asked to confess that he was taken into custody from the Nepali side.

"We ran to return to India when they started firing, but they dragged me from the Indian side, hit me with a rifle butt and took me to Nepal's Sangrampur. They told me to confess that I was brought there from Nepal. I told them you can kill me but I was brought there from India," said Kishore.

Kishore's son also said that Nepali personnel started abusing them and hit him and his father.

Speaking to ANI, Kishore's son said, "We went to meet my brother-in-law. Security personnel started abusing me but I could not understand their language. However, my brother's wife asked them to not abuse. After that, they came to the Indian side and hit me. I told my father about the incident and he confronted them."

"They started beating him and called fellow personnel who started firing and dragged my father from the Indian side, hit him with a rifle butt and took him to Nepal''s Sangrampur," he said.

Relations have become strained between India and Nepal after the latter released a map showing parts of Indian Territory-Lipulekh, Kalapani and Limpiyadhura as its own.

Jun 13: Requiring the wearing of masks to prevent the spread of the novel coronavirus in areas at the epicenter of the global pandemic may have prevented tens of thousands of infections, a new study suggests.

Mask-wearing is even more important for preventing the virus' spread and the sometimes deadly COVID-19 illness it causes than social distancing and stay-at-home orders, researchers said, in the study published in PNAS: The Proceedings of the National Academy of Sciences of the USA.

Infection trends shifted dramatically when mask-wearing rules were implemented on April 6 in northern Italy and April 17 in New York City - at the time among the hardest hit areas of the world by the health crisis - the study found.

"This protective measure alone significantly reduced the number of infections, that is, by over 78,000 in Italy from April 6 to May 9 and over 66,000 in New York City from April 17 to May 9," researchers calculated.

When mask-wearing went into effect in New York, the daily new infection rate fell by about 3% per day, researchers said. In the rest of the country, daily new infections continued to increase.

Direct contact precautions - social distancing, quarantine and isolation, and hand sanitizing - were all in place before mask-wearing rules went into effect in Italy and New York City. But they only help minimize virus transmission by direct contact, while face covering helps prevent airborne transmission, the researchers say.

"The unique function of face covering to block atomization and inhalation of virus-bearing aerosols accounts for the significantly reduced infections," they said. That would indicate "that airborne transmission of COVID-19 represents the dominant route for infection."

The U.S. Center for Disease Control and Prevention on Friday urged organizers of large gatherings that involve "shouting, chanting or singing to strongly encourage the use of cloth face coverings to lower the risk of spreading the coronavirus."
