Indian women rarely make false claims, delay in filing rape case doesn't mean she lied: HC

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."

New Delhi, Mar 15: The number of novel coronavirus cases in the country rose to 107 on Sunday, with 12 fresh cases in Maharashtra, the Union Health Ministry said.

The number of cases include two persons who died in Delhi and Karnataka.

While a 76-year-old man from Kalaburagi who had recently returned from Saudi Arabia died on Thursday, a 68-year-old woman in Delhi who had tested positive for coronavirus passed away at the Ram Manohar Lohia (RML) Hospital on Friday night.

Delhi has reported seven positive cases and Uttar Pradesh 11 so far. Karnataka has six coronavirus patients while Maharashtra 31, Ladakh three and Jammu and Kashmir 2. Telangana reported three cases.

Besides, Rajasthan also reported two cases. Tamil Nadu, Andhra Pradesh and Punjab have reported one case each.

Kerala has recorded 22 cases, including three patients who were discharged last month after they recovered from the contagious infection with flu-like symptoms.

The total number of confirmed cases includes 17 foreigners -- 16 Italian tourists and a Canadian, the ministry officials said

Amid rising coronavirus cases in India, the government has asked people not to panic, saying no community transmission of the virus has been observed and there has only been a few cases of local transmission so far and that it is "not a health emergency" in India at present.

With the World Health Organisation (WHO) declaring COVID-19 a pandemic, a Health Ministry official said over 4,000 people who had come in contact with the 93 positive cases have been identified through contact tracing and were being tracked while 42,000 people across the country are under community surveillance.

He said all essential facilities like community surveillance, quarantine, isolation wards, adequate personal protective equipment (PPEs), trained manpower, rapid response teams are being strengthened further in all states and union territories.

The government on Wednesday suspended all visas, barring a few categories like diplomatic and employment, in an attempt to prevent the spread of coronavirus.

It has asked Indian nationals to avoid all non-essential travel abroad.

All incoming international passengers returning to India should self-monitor their health and follow the required do's and dont's as detailed by the government.
