Never ever visited any rowdy’s home; will retire from politics if allegations proven: UT Khader

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.

Bengaluru, Jul 1: Karnataka Primary and Secondary Education Minister S Suresh Kumar on Wednesday played down reports about confusion regarding valuation of Second Pre- University and the Secondary School Leaving Certificate exam papers.

"Creating confusion has become a habit. There was confusion before the exam, during the exam and now confusion about the valuation of the exam papers," Kumar told reporters in Ramanagara when asked about the confusion over the valuation of answer sheets.

He had gone there to inspect a few centres where the SSLC or the 10th standard exams are underway.

The minister reminded people not to speak about the abilities of the students with contempt.

"Our students have toiled hard and are enthusiastically appearing for the examination. They are eligible for the marks they will score. So we should not speak about our children with disrespect," Kumar said.

The Education Minister said he had spoken to many leaders including former chief ministers Siddaramaiah and H D Kumaraswamy on conducting the examinations.

"Kumaraswamy had insisted on postponing the examination. I personally spoke to him and apprised him about the steps taken by us. I told him that we will work with more sincerity to ensure the safety of the children," Kumar said.

The SSLC exam was scheduled to take place from March 27 but due to the coronavirus-induced lockdown, it was postponed.

While the CBSE and a few other states either decided to give marks based on the students' performance in the previous examinations such as quarterly and half-yearly exams or gave general promotion to the students, Karnataka went ahead to hold the exam.

According to Karnataka Secondary Education Examination Board officials, around 8.5 lakh students have enrolled this year for the SSLC examination.

The exams are being held at 2,879 exam centres across the state.

Prior to the SSLC examination, the last exam of the Second PUC was also conducted on June 18, which was also put on hold due to the lockdown.
