Swaraj seeks report into kidnapping of 2 Hindu girls in Pakistan’s Sindh province

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, May 26: As India ranked 10th in the global infection list, overtaking Iran, which was an early hotspot of coronavirus, India's top medical body has said the human trials of COVID-19 vaccine may begin at least in six months.

Dr. Rajni Kant, Director Regional Medical Research Centre and Head at the Indian Council of Medical Research (ICMR) said, "The virus strain isolated at the National Institute of Virology (NIV) laboratory in Pune will be used to develop the vaccine, and this strain has been successfully transferred to the Bharat Biotech International Ltd. (BBIL). It is expected that the human trials of the vaccine will begin in at least six months."

Queried on the focus areas as India inches closer to 1.4 lakh COVID-19 cases, Kant said we should not get anxious about the rapid increase in numbers, especially in the past week, which saw 5,000 Covid-19 cases daily, instead focus on protecting the most vulnerable group.

"We should not fear from increasing Covid-19 cases. The elderly and people with comorbidities need protection. This is the highly vulnerable group, and we need to deploy resources and develop strategies to keep the mortality rate as low as possible in this group," said Kant.

Initially, it was assumed that the country would require thousands of ventilators, but last week, the health ministry said only 0.45 per cent of COVID-19 cases need ventilator support.

Kant insisted the focus should be on five per cent to 10 per cent serious patients. "We are testing more than one lakh daily and our case fatality rate is already one of the lowest in the world. In absence of vaccine, people should follow social distancing guidelines," he added

On the significance of the recovery rate, Kant said the increasing recovery rate of the COVID-19 patients, which is at 41 per cent, is a bright spot in India's fight against deadly viral infection.

Queried on large scale COVID-19 cases in Mumbai, Delhi and Ahmedabad, Kant said the population density in these regions is very high, which proves to be the just right environment for the viral infection.

He insisted on developing robust cluster management strategies in the hard-hit coronavirus spots, and the movement of people should be curtailed in these areas.

"Currently, a lot of people are moving around easily and avoiding social distancing norms. The first phase of the lockdown was very effective, but now things have changed," added Kant.
