'We Did Work, They Took Credit': Union Minister's Swipe at Arvind Kejriwal

New Delhi, May 29: With the highest spike of 7,466 more COVID-19 cases and 175 deaths reported in the past 24 hours, India's COVID-19 tally reached 1,65,799 on Friday, according to the Union Ministry of Health and Family Welfare.

The number of active coronavirus cases stands at 89,987 while 71,105 people have been cured or recovered and one patient has migrated, it said. The death toll due to the infection has reached 4,706 in the country.

Maharashtra is the worst affected state with 59,546 cases. Tamil Nadu has recorded as many as 19,372 cases while Gujarat and Delhi have recorded 15,562 and 16,281 coronavirus cases respectively.

New Delhi, April 3: The Government on Thursday launched a mobile app developed in public-private partnership as part of efforts to contain the spread of coronavirus.

"The app, called 'AarogyaSetu' will enable people to assess themselves the risk for their catching the coronavirus infection," an official release said.

It said that the app will calculate this based on their interaction with others, using cutting edge Bluetooth technology, algorithms and artificial intelligence.

"Once installed in a smartphone through an easy and user-friendly process, the app detects other devices with AarogyaSetu installed that come in the proximity of that phone. The app can then calculate the risk of infection based on sophisticated parameters," the release said.

It said that the app will help the government take necessary timely steps for assessing risk of spread of COVID-19 infection and ensuring isolation where required.

"The app's design ensures privacy. The personal data collected by the app is encrypted using state-of-the-art technology and stays secure on the phone till it is needed for facilitating medical intervention," the release said.

It said the app is available in 11 languages and has highly scalable architecture.

"This app is a unique example of the nation's young talent coming together and pooling resources and efforts to respond to a global crisis. It is at once a bridge between public and private sectors, digital technology and health services delivery," the release said.

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.
