I am a Hindu first, MP later, Ram Mandir is my priority: Nalin Kumar Kateel

Mangaluru, May 15: In a shocking development, five residents of Udupi district, who recently came from United Arab Emirates today tested positive for covid-19.

As many as 49 passengers among over 175 repatriates who were brought from Dubai to Mangaluru International Airport on May 12 were from Udupi district.

Hence they were quarantined in Udupi district and their throat swabs were sent for testing on the same day. Today, five of them obtained positive report. They were today shifted to TMA Pai covid-hospital from their hotel rooms.

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."

Bengaluru, May 19: Karnataka on Tuesday recorded the highest single-day rise in the COVID-19 cases in the state as a whooping 149 people tested positive for the virus. With the spike in new cases, the overall tally has risen to 1,395.

This is for the first time the state recorded 100 plus cases in a single day. So far, 40 people have also succumbed to the virus including three deaths today. 

The new deaths consist of a 61-year-old male patient, a resident of Ballari; a 65-year-old male patient, a resident of Vijayapura; and a 54-year-old male patient from Bengaluru.

Among the new cases, a maximum of 71 are reported from Mandya, followed by 22 in Davanagere, 10 in Shivamogga, 13 in Kalaburgi, six in Bengaluru Urban, four each in Udupi and Uttara Kannada, five in Chikkamagaluru, three in Hassan and one each in Yadagiri, Chitradurga, Vijayapura, Gadag.

Most of the new cases are of the people who traveled to Mumbai in Maharashtra, Solapur, Ahmedabad, and Kerala.

The remaining are those who came in contact with the people who had tested positive earlier.

At present, 811 people are actively taking treatment, while 543 have been discharged after recovery.
