'If Cong, SP have faith in Ali, we have Bajrang Bali'

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.

New Delhi, Apr 28: Nafisa Ali took to Instagram to share the inspiring story of her niece, Diya Naidu, who donated her plasma to help patients suffering from Covid-19 after recovering from the disease. The veteran actress shared a photo of her niece from the hospital bed and asked fans to read Diya's post to get a detailed account of her experience.

Nafisa wrote, "Diya Naidu my niece - a COVID19 hero - is back home after donating her plasma - looks like liquid gold - it’s value is priceless as it will save lives. So please read her COVID19 story and share the information that is first hand. It is the need of the hour. Help save lives. #diyanise. #diyanaidu #covid_19 #india (sic)."

Diya Naidu, who is a dancer and choreographer based in Bengaluru, revealed in her Instagram post that she has donated her plasma for other Covid-19 patients. She said that the method has been super effective wherever it's been tried.

Earlier, Nafisa Ali gave a shout-out to her niece on Instagram and penned a heartfelt note for her. She wrote, "I am so grateful to you brave child - a COVID19 warrior (living in Bangalore) has agreed to donate her plasma to help cure other COVID19 serious patients (sic)."

Explaining the process of plasma therapy to treat Covid-19 patients, she wrote, "The process of donating plasma to treat COVID-19 is not very complex and can be done in just two hours. One of the most discussed methods of treatment of the disease caused by the novel coronavirus is plasma therapy, which involves the transfusion of plasma from a convalescent coronavirus patient to a critical patient. The blood of a recovering patient is rich in antibodies produced by the body to fight the virus, which are expected to help the critical patient recover (sic)."

Plasma therapy has been suggested to treat people suffering from Covid-19. People, who have recovered from the disease, are donating plasma as it contains antibodies to fight the disease. Earlier, Kanika Kapoor, who was the first Bollywood celebrity to be diagnosed with the disease, also offered to donate her plasma. She has recovered from Covid-19 and is currently living with her family in Lucknow.

London/Milan, Jun 2: World Health Organization experts and a range of other scientists said on Monday there was no evidence to support an assertion by a high profile Italian doctor that the coronavirus causing the COVID-19 pandemic has been losing potency.

Professor Alberto Zangrillo, head of intensive care at Italy's San Raffaele Hospital in Lombardy, which bore the brunt of Italy's COVID-19 epidemic, on Sunday told state television that the new coronavirus "clinically no longer exists".

But WHO epidemiologist Maria Van Kerkhove, as well as several other experts on viruses and infectious diseases, said Zangrillo's comments were not supported by scientific evidence.

There is no data to show the new coronavirus is changing significantly, either in its form of transmission or in the severity of the disease it causes, they said.

"In terms of transmissibility, that has not changed, in terms of severity, that has not changed," Van Kerkhove told reporters.

It is not unusual for viruses to mutate and adapt as they spread, and the debate on Monday highlights how scientists are monitoring and tracking the new virus. The COVID-19 pandemic has so far killed more than 370,000 people and infected more than 6 million.

Martin Hibberd, a professor of emerging infectious disease at the London School of Hygiene & Tropical Medicine, said major studies looking at genetic changes in the SARS-CoV-2 virus that causes COVID-19 did not support the idea that it was becoming less potent, or weakening in any way.

"With data from more than 35,000 whole virus genomes, there is currently no evidence that there is any significant difference relating to severity," he said in an emailed comment.

Zangrillo, well known in Italy as the personal doctor of former Prime Minister Silvio Berlusconi, said his comments were backed up by a study conducted by a fellow scientist, Massimo Clementi, which Zangrillo said would be published next week.

Zangrillo told Reuters: "We have never said that the virus has changed, we said that the interaction between the virus and the host has definitely changed."

He said this could be due either to different characteristics of the virus, which he said they had not yet identified, or different characteristics in those infected.

The study by Clementi, who is director of the microbiology and virology laboratory of San Raffaele, compared virus samples from COVID-19 patients at the Milan-based hospital in March with samples from patients with the disease in May.

"The result was unambiguous: an extremely significant difference between the viral load of patients admitted in March compared to" those admitted last month, Zangrillo said.

Oscar MacLean, an expert at the University of Glasgow's Centre for Virus Research, said suggestions that the virus was weakening were "not supported by anything in the scientific literature and also seem fairly implausible on genetic grounds."
