I shall live on their memories: Mother who lost all 7 children in Fujairah fire

Riyadh, Feb 28: Saudi Arabia on Thursday (Feb 27) suspended visas for visits to Islam's holiest sites for the "umrah" pilgrimage, an unprecedented move triggered by coronavirus fears that raises questions over the annual hajj.

The kingdom, which hosts millions of pilgrims every year in the cities of Mecca and Medina, also suspended visas for tourists from countries with reported infections as fears of a pandemic deepen.

Saudi Arabia, which so far has reported no cases of the virus but has expressed alarm over its spread in neighbouring countries, said the suspensions were temporary. It provided no timeframe for when they will be lifted.

"The kingdom's government has decided to take the following precautions: suspending entry to the kingdom for the purpose of umrah and visit to the Prophet's mosque temporarily," the foreign ministry said in a statement.

"Suspending entry into the kingdom with tourist visas for those coming from countries, in which the spread of the new coronavirus (COVID-19) is a danger."

The move comes as Gulf countries implement a raft of measures, including flight suspensions and school closures, to curb the spread of the disease from people returning from pilgrimages to Iran.

Even as the number of fresh coronavirus cases declines at the epicentre of the disease in China, there has been a sudden increase across the Middle East.

Since its outbreak, the United Arab Emirates has reported 13 coronavirus cases, Kuwait has recorded 43, Bahrain has 33 and Oman is at four cases.

Iran has emerged as a major hotspot in the region, with 19 fatalities from 139 infections - the highest death toll outside China, where COVID-19 originated.

While no cases have been reported in Saudi Arabia, one citizen is reported to be infected in Kuwait along with four Saudi women in Bahrain - all of whom had returned from Iran.

'UNPRECEDENTED' MOVE

The umrah, which refers to the Islamic pilgrimage to Mecca that can be undertaken at any time of year, attracts millions of devout Muslims from all over the globe each year.

There was no clarity over how the move would affect the annual hajj pilgrimage due to start in late July.

Some 2.5 million faithful travelled to Saudi Arabia from across the world to take part in last year's hajj - one of the five pillars of Islam.

The event is a key rite of passage for Muslims and a massive logistical challenge for Saudi authorities, with colossal crowds cramming into relatively small holy sites.

"This move by Saudi Arabia is unprecedented," Ghanem Nuseibeh, founder of London-based risk consultancy Cornerstone Global Associates, told news agency.

"The concern for Saudi authorities would be Ramadan, which starts at the end of April, and hajj afterwards, should the coronavirus become a pandemic."

The holy fasting month of Ramadan is considered a favourable period by Muslim pilgrims to perform the umrah.

Saudi Arabia's custodianship of Mecca and Medina - Islam's two holiest sites - is seen as the kingdom's most powerful source of political legitimacy.

But a series of deadly disasters over the years has prompted criticism of the Sunni kingdom's management of the pilgrimage.

In September 2015, a stampede killed up to 2,300 worshippers - including hundreds of Iranians - in the worst disaster ever to strike the pilgrimage.

The pilgrimage forms a crucial source of revenue for the government, which hopes to welcome 30 million pilgrims annually to the kingdom by 2030.

De facto ruler Crown Prince Mohammed bin Salman's Vision 2030 reform plan seeks to shift the economy of Saudi Arabia - the world's top crude exporter - away from oil dependency towards other sources of revenue, including religious tourism.

Kolkata, Mar 9: A diabetic man died in the isolation ward of a hospital in West Bengal's Murshidabad on Sunday, a day after he was admitted there with suspected symptoms of coronavirus following his return from Saudi Arabia.

According to doctors, he was admitted to the hospital with fever, cough and cold.

Though test results of his blood and swab samples for novel coronavirus were awaited, it can be said that he died probably of diabetes, Director of Health Services Ajay Chakraborty told PTI.

"The man was highly diabetic and was on insulin. He returned home from Saudi Arabia and had no money to take insulin for the last three to four days.

"He was also suffering from fever, cough and cold. He was admitted to the isolation ward of the Murshidabad Medical College and Hospital yesterday and died today," the health services director said.

"We are waiting for the results of medical tests. The possibility of his death due to novel coronavirus infection is remote," he said.

However, precautions will be taken during the last rites of the victim according to the directives set by the central and state governments for patients who die of the virus, another senior official said.

"Family members will not be allowed to touch the body since the man had been suffering from cough and breathlessness. Those performing his last rites will be given protective gear, masks and gloves. Though test results are yet to be known, we do not want to take any chance," he said.

Meanwhile, the state health department has issued a directive to all private medical facilities to create a system for assessing all patients at admission allowing early recognition of possible COVID-19 infection and immediate isolation of patients with suspected novel coronavirus infection in an area separate from other patients.

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."
