Varavara Rao tests coronavirus positive

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, Apr 5: Joining efforts to fight COVID-19, the Defence Research and Development Organisation (DRDO) has designed a full-body disinfection chamber and a special face protection mask for healthcare professionals, officials said.

The special chamber called 'PSE' has been designed by Vehicle Research Development Establishment (VRDE), Ahmednagar, a DRDO Laboratory.

The walk through enclosure is designed for personnel decontamination, one person at a time. It is a portable system equipped with sanitiser and soap dispenser, officials said.

The decontamination is started using a foot pedal at the entry. On entering the chamber, electrically-operated pump creates a disinfectant mist of hypo sodium chloride for disinfecting, the DRDO said in a statement.

The mist spray is calibrated for an operation of 25 seconds and stops automatically indicating completion of operation. As per procedure, personnel undergoing disinfection will need to keep their eyes closed while inside the chamber, it said.

The system consists of roof mounted and bottom tanks with a total of 700 litres capacity. Approximately 650 personnel can pass through the chamber for disinfection until the refill is required, the DRDO said.

The system has see-through glass panels on side walls for monitoring purpose and is fitted with lights for illumination during night-time operations, it added.

This system can be used for disinfection of personnel at the areas of controlled ingress and egress such as entry and exit to hospitals, malls, office buildings and critical installations, officials said.

Also, Research Centre Imarat (RCI), Hyderabad, and Terminal Ballistics Research Laboratory (TBRL), Chandigarh, have developed face protection mask for healthcare professionals handling COVID-19 patients, the DRDO added.

Its light weight construction makes it convenient for comfortable wear for long duration. This design uses commonly available A4 size Over-Head Projection (OHP) film for face protection, it said.

One thousand face shields are being produced daily in TBRL and provided to Postgraduate Institute of Medical Education and Research (PGIMER), Chandigarh, it said.

Similarly, 100 are produced at RCI and these have been handed over to Employees' State Insurance Corporation (ESIC), Hyderabad. A demand of 10,000 shields has been received from PGIMER and ESIC hospitals based on successful user trials, the DRDO added.

Washington, Jun 9: The defacement of Mahatma Gandhi's statue by unknown miscreants was a "disgrace", US President Donald Trump has said, days after it was vandalised with graffiti and spray painting during the nationwide protests against the custodial killing of African-American George Floyd.

The statue, which is across the road from the Indian Embassy, was vandalised on the intervening night of June 2 and 3, prompting the Indian embassy to register a complaint with the local law enforcement agencies.

The incident happened during the week of nationwide protests against the custodial killing of Floyd in Minneapolis on May 25.

"It was a disgrace," Trump made the brief comment at the White House on Monday when asked about the incident.

The Indian Embassy here has taken up the matter with the US Department of State for early investigation into the matter, as also with the Metropolitan Police and National Park Service.

It is working with the US Department of State, Metropolitan Police and National Park Service for expeditious restoration of the statue at the park.

The US president and First Lady Melania Trump, during their visit to India in February, had spent considerable time at the Gandhi Ashram in Ahmedabad. Prime Minister Narendra Modi had personally given them a tour of the historic place.

"The First Lady and I have just had a pleasure of visiting Mahatma Gandhi's Ashram, a few miles from here, where he launched the famous Salt March," Trump had said during his address at the Namaste Trump rally at the Motera Stadium in Ahmedabad on February 24. A day later, Trump and the first lady also laid a wreath at Raj Ghat in New Delhi.

Pictures of Trump and the first lady with Gandhi's spinning wheel during their visit to the Sabarmati Ashram in Ahmedabad are seen hanging on the walls of the White House.

Last week, top US lawmakers and the Trump Campaign condemned the vandalisation of the statue.

"Very disappointing," tweeted Kimberly Guilfoyle, advisor to Donald J Trump for President Inc. and National Chair of the Trump Victory Finance Committees.

North Carolina Senator Tom Tillis said, "It's disgraceful to see the defacing of the Gandhi statue" in Washington DC.

"Gandhi was a pioneer of peaceful protesting, demonstrating the great change it can bring. Rioting, looting and vandalising do not bring us together, he said.

Senator Marco Rubio said, "more evidence that violent radicals and run of the mill crazies have hijacked legitimate protests to create anarchy or for their own purposes."

Protests against the custodial killing of Floyd turned violent in the US and prestigious monuments were damaged. In Washington DC, protestors burnt a historic church and damaged monuments like the Lincoln Memorial.

US Ambassador to India Ken Juster apologised for the incident.

"So sorry to see the desecration of the Gandhi statue in Wash, DC. Please accept our sincere apologies," he said.

"Appalled as well by the horrific death of George Floyd and the awful violence and vandalism. We stand against prejudice & discrimination of any type. We will recover and be better," he said in a tweet last week.

One of the few statues of a foreign leader on a federal land in Washington DC, the statue of Gandhi was dedicated by former prime minister Atal Bihari Vajpayee in the presence of the then US president Bill Clinton on September 16, 2000, during his state visit to the US.
