Delhi: Cong promises unemployment allowance, cashback schemes, 300 units free power

Thiruvananthapuram, Apr 13: Three more people in Kerala tested positive for novel coronavirus disease on Monday, said Chief Minister Pinarayi Vijayan.

"With 3 new COVID-19 cases, the total number of cases in the state has reached 378," said Vijayan at a press conference.

Giving a break-up of the three confirmed COVID-19 cases, he said, "Of the 3 cases, 2 are from Kannur and 1 is from Palakkad."

He further said, "Till date, 15,683 samples tested, out of which 14,829 tested negative."

However, the total number of positive cases is decreasing, the Chief Minister added.

According to a recent update by the Ministery of Health and Family Welfare, the total number of cases in the country has reached 9352.

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."

Kochi, Apr 16: As many as 268 British citizens stranded in Kerala due to the nationwide lockdown were airlifted by British Airways on Wednesday from Thiruvananthapuram and Cochin International Airports.

The flight took off from Thiruvananthapuram to London's Heathrow Airport with 110 passengers at 7.30 pm. Later, 158 more passengers boarded the flight from Cochin airport at 10.07 pm.
A medical team, including four doctors, screened the passengers at the Thiruvananthapuram airport before they boarded the flight.

Earlier this month, the first charter flight from India reached London's Stansted with 317 British nationals on board from Goa.

The British government had earlier announced the operation of 19 chartered flights to evacuate its nationals who are stranded in India amid travel restrictions owing to the coronavirus crisis.
