'Russian air raids kill 13 civilians including 6 children in Syria'

New Delhi, Jun 4: India's Defence Secretary Ajay Kumar tested positive for COVID-19 on Wednesday, following which the defence ministry carried out a massive contact-tracing exercise, official sources said.

Kumar's condition is stable and he is currently under home-quarantine, they said.

At least 35 officials working at the ministry's headquarters in South Block in the Raisina Hills have been sent on home quarantine after reports of Kumar testing positive for the infection emerged on Wednesday morning.

There was no official comment on Kumar's health condition. The defence ministry spokesperson refused to comment on the issue.

It is learnt that Defence Minister Rajnath Singh did not attend office as part of a precautionary measure.

The offices of the defence minister, the defence secretary, the Army Chief and the Navy Chief are on the first floor of the South Block.

The sources said all laid down protocols on contact-tracing and quarantining of people are being scrupulously followed.

Dhaka, Jan 3: Bangladesh's paramilitary force chief said on Thursday that a total of 445 Bangladeshi nationals returned from India in last two months following the publication of the National Register of Citizens (NRC) by the Indian government.

Border Guard Bangladesh (BGB) Director General Maj Gen Md Shafeenul Islam disclosed the figure during a press briefing here.

"About 1,000 people were arrested in 2019 for illegal border crossings from India to Bangladesh, with 445 of them returning home in November and December," he said.

After verifying their identities through local representatives, BGB came to know that all the intruders are Bangladeshis, Islam said, adding that 253 cases were lodged against them for illegal trespass, while initial investigations found that at least three of them were human traffickers.

The BGB Director said the trespassing did not create any tension between the border forces of Bangladesh and India.

Last week, Islam visited India where he said that the creation of the NRC is completely an "internal affair" of India and the cooperation between the border guarding forces of the two countries is very good.

He said the BGB will continue to do its work of preventing illegal border crossings as per its mandate.

A BGB delegation, led by Islam, was on a bilateral visit to India to hold DG-level border talks with its counterparts, the Border Security Force (BSF).

The talks took place from December 26-29, during which a host of issues related to cross-border smuggling and activities of criminals and others along the 4,096-km-long front were discussed.

Responding to a question, Islam said, "No discussion was held at the conference over the (NRC) issue".

He said during the five-day talks held in New Delhi, the BGB demanded that the BSF should take effective steps to prevent killings of Bangladeshis on frontiers as casualty figures sharply rose in 2019.

"The number of border killings in 2019 was highest in the last four years. As per our calculation, the number of such unexpected deaths was 35," the BGB chief said.

However, the BSF estimate of the casualty figure is much lower than our calculation, he said.

Islam said the BSF is following the policy of maintaining maximum restraint and minimal use of force even after being attacked by "armed border offenders".

A statement issued by the BSF last month in New Delhi after the conclusion of the DG-level talks said, "On the concern of the BGB regarding the death of Bangladeshi nationals on borders, it was informed to them that a non-lethal weapon policy is strictly followed by BSF personnel on borders.

"Firing is resorted to only in self-defence, when BSF patrols are gheraoed and attacked by ‘dah’ (a sharp-edged weapon) etc. It was specified that the BSF does not discriminate between criminals based on nationality," it said.

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."
