Barack Obama 'Not Optimistic' On Syria As Aleppo Pummelled

New York, May 8: An Indian-American father and daughter, both doctors in New Jersey, have died due to the COVID-19, with Governor Phil Murphy describing their demise as “particularly tough" and hailed them for dedicating their lives for others.

Satyender Dev Khanna, 78, was a surgeon who served both on staff and as the head of the surgical departments for multiple hospitals across New Jersey for decades.

Priya Khanna, 43, was a double board-certified in both internal medicine and nephrology. She was Chief of Residents at Union Hospital, now part of RWJ Barnabas Health.

"Dr Satyender Dev Khanna and Dr Priya Khanna were father and daughter. They both dedicated their lives to helping others. This is a family dedicated to health and medicine. Our words cannot amply express our condolences," New Jersey Governor Murphy tweeted on Thursday.

“Both dedicated their lives to helping others and we lost both of them to COVID-19,” Murphy said during a press conference on Thursday, saying their demise is a "particularly tough one.”

Satyender passed away at the Clara Maass Medical Center where he had worked for more than 35 years.

Murphy described him as a "pioneering doctor” who was one of the first surgeons to perform laparoscopic surgery in the state. He is being remembered by colleagues as a “gentle and caring physician."

“And for a doctor, I'm not one, but I would bet, I don't think there could be a more fitting way to be remembered, or a nurse or a healthcare worker of any kind,” Murphy said, adding that the doctor had a passion for bicycling, and he often found peace from the hustle of the hospital in biking along the Jersey Shore.

Priya did all of her medical training in New Jersey and then did her fellowship in nephrology in South Jersey with the Cooper Health System. Like her father, she too worked at Clara Maass, where she died.

She was also Medical Director at two dialysis centres in Essex County and “took pride” in teaching the next generation of doctors, Murphy said, adding that the ICU physician who cared for Priya Khanna was trained and taught by her as well.

“Priya will be remembered as a caring and selfless person who put others first. And even while in the hospital, fighting her own battle, she continued to check up on her mom and dad and her family,” Murphy said.

“This is a family, by the way, dedicated to health and medicine,” he said.

The governor spoke with Satyender's wife Komlish Khanna, who is a paediatrician. The couple has two more daughters - Sugandha Khanna, an emergency medicine physician and Anisha Khanna, a paediatrician.

“Unbelievable. Our words cannot amply express our condolences nor, I am sure, can they express the pain that the Khanna family is feeling. But I hope that the fact that our entire state mourns with them is some small comfort. And we mourn everyone we have lost. We commit in their memory to saving as many lives as we can,” Murphy said.

Jan 28: China said on Tuesday that 106 people had died from a new coronavirus that is spreading across the country, up from the previous toll of 81.

The number of total confirmed cases in China rose to 4,515 as of Jan. 27, the National Health Commission said in a statement, up from 2,835 reported a day earlier.

The United States warned against travel to China on Monday and Canada issued a more narrow travel warning as the death toll from the spreading coronavirus passed 100, with tens of millions stranded during the biggest holiday of the year and global markets rattled.

Global stocks fell, oil prices hit three-month lows, and China's yuan dipped to its weakest level in 2020 as investors fretted about damage to the world's second-biggest economy from travel bans and the Lunar New Year holiday, which China extended in a bid to keep people at home.

The health commission of China's Hubei province said on Tuesday that 100 people had died from the virus as of Jan. 27, according to an online statement, up from the previous toll of 76, with the number of confirmed cases in the province rose to 2,714.

Other fatalities have been reported elsewhere in China, including the first in Beijing, bringing the deal toll to 106 so far, according to the People's Daily. The state newspaper put the total number of confirmed cases in China at 4,193, though some experts suspect a much higher number.

On Monday, US President Donald Trump offered China whatever help it needed, while the State Department said Americans should "reconsider" visiting all of China due to the virus.

Canada, which has two confirmed cases of the virus and is investigating 19 more potential cases, warned its citizens to avoid travel to China's Hubei province, at the heart of the outbreak.

Authorities in Hubei province are taking increasing flak from the public over their initial response to the virus. Chinese Premier Li Keqiang visited the city of Wuhan, epicentre of the outbreak, to encourage medical workers and promise reinforcements.

Visiting Wuhan in blue protective suit and mask, Li praised medics, said 2,500 more workers would join them in the next two days, and visited the site of a new hospital to be built in days.

The most senior leader to visit Wuhan since the outbreak, Li was shown on state TV leading medical workers in chants of "Wuhan jiayou!" - an exhortation to keep their strength up.

China's ambassador to the United Nations, following a meeting with UN Secretary-General António Guterres on Monday, said "the Chinese government attaches paramount importance to prevention and control of the epidemic, and President Xi Jinping has given important instructions. ...

"China has been working with the international community in the spirit of openness, transparency and scientific coordination," he said.

Guterres said in a statement, "The UN appreciates China's effort, has full confidence in China's ability of controlling the outbreak, and stands ready to provide any support and assistance."

MOUNTING ANGER

On China's heavily censored social media, officials have faced mounting anger over the virus, which is thought to have originated from a market where wildlife was sold illegally.

Some criticised the governor of Hubei province, of which Wuhan is the capital, after he corrected himself twice during a news conference over the number of face masks being produced.

"If he can mess up the data multiple times, no wonder the disease has spread so severely," said one user of the Weibo social media platform.

In rare public self-criticism, Wuhan Mayor Zhou Xianwang said the city's management of the crisis was "not good enough" and indicated he was willing to resign.

The central Chinese city of 11 million people is in virtual lockdown and much of Hubei, home to nearly 60 million people, is under travel curbs.

Elsewhere in China, people from the region faced questioning about their movements. "Hubei people are getting discriminated against," a Wuhan resident complained on Weibo.

Cases linked to people who travelled from Wuhan have been confirmed in a dozen countries, from Japan to the United States, where authorities said they had 110 people under investigation in 26 states. Sri Lanka was the latest to confirm a case.

INVESTORS WORRIED

Investors are worried about the impact. The consensus is that in the short term, economic output will be hit as authorities limit travel and extend the week-long New Year holiday — when millions traditionally travel by rail, road and plane - by three days to limit spread of the virus.

Asian and European shares tumbled, with Japan's Nikkei average sliding 2%, its biggest one-day fall in five months. Demand spiked for safe-haven assets such as the Japanese yen and Treasury notes. European stocks fell more than 2%.

The US S&P 500 closed down nearly 1.6%.

"China is the biggest driver of global growth so this couldn't have started in a worse place," said Alec Young, FTSE Russell's managing director of global markets research.

During the 2002-2003 outbreak of Severe Acute Respiratory Syndrome (SARS), which originated in China and killed nearly 800 people globally, air passenger demand in Asia plunged 45%. The travel industry is more reliant on Chinese travellers now.

Chinese-ruled Hong Kong, which has had eight cases, banned entry to people who had visited Hubei recently.

Some European tour operators cancelled trips to China, while governments around the world worked on repatriating nationals.

Officially known as 2019-nCoV, the newly identified coronavirus can cause pneumonia, but it is still too early to know just how dangerous it is and how easily it spreads.

"What we know about this virus it that transmission occurs through human contact but we are speaking of close contact, i.e. less than a meter," said Jerome Salomon, a senior official with France's health ministry.

"Crossing someone (infected) in the street poses no threat," he said. "The risk is low when you spend a little time near that person and becomes higher when you spend a lot of time near that person."

May 30: Warning of the tightrope walk ahead as governments battle the coronavirus crisis, Nobel laureate Peter Charles Doherty has expressed concern about densely populated countries such as India relaxing lockdown norms while also describing a complete shutdown as “an economic and social impossibility”.

The Australian immunologist, who cautioned that the number of COVID-19 cases will rise in the coming days, said the earliest time frame for an effective vaccine “going into large numbers of people” is nine to 12 months.

"If all goes well with testing, we could know if some of the candidate vaccines are both safe and effective as early as September/October. Then, rolling a vaccine out will depend on the type of product and how quickly it can be made, put in vials and so forth," Doherty told PTI in an email interview from Melbourne.

The novel coronavirus, he added, does not change fast like influenza and, from what is known so far, “the same vaccine should work everywhere”.

Doherty, who is with the Department of Microbiology and Immunology at the Doherty Institute, University of Melbourne, won the Nobel Prize for Medicine in 1996 for his discovery of how the body’s immune system distinguishes virus-infected cells from normal ones.

Discussing the lockdown, he said, "If it was purely a matter of hard science, everywhere should stay locked down. But that’s pretty much an economic and social impossibility.”

The expectation, he said, is the numbers will rise and limiting spread will depend on people acting responsibly and the capacity for rapid response and extensive contact testing.

“And in a densely populated country like India I think that it will be very difficult," the scientist said.

Several countries, including India, began relaxing lockdown norms in mid-May despite the WHO’s warning about a second wave. India’s lockdown began on March 25 and has since been extended. The fourth phase ends on Sunday.

Asked whether there are any alternatives to a lockdown, the 79-year-old said, "There is no other option other than closing borders. South Korea, for example, conducted massive, intensive testing and contact tracing in a wealthy country with a very disciplined population. Otherwise, not till we have effective vaccines."

He added that he personally doesn’t see the point of closing borders for people coming in if there’s already a high incidence of disease in the community, “unless it’s to avoid the need to care for them and use scarce hospital beds".

According to Doherty, the coronavirus "is a new virus which has come straight out of nature".

“It (the virus) has moved so rapidly across the world because of people travelling on international planes as well as tourist ships," he added.

The immunologist also warned against the use of hydroxychloroquine to treat COVID-19, and said current and planned trials of the anti-malaria drug should be stopped.

“My understanding is that the use of the drug in severe disease is definitely contra-indicated, but it’s not yet clear whether, if taken under medical supervision, it could have some useful effect if taken early on, or as a preventive. Those trials just haven’t been done properly," Doherty noted.

The Indian Council of Medical Research (ICMR) has backed the use of hydroxychloroquine as a preventive against COVID-19 even after the WHO suspended clinical trials of the drug citing safety concerns.

Asked whether plasma therapy can be an effective treatment for COVID-19, Doherty said, "We lack good properly controlled trials but, especially if the plasma has been tested for antibody levels and there’s evidence of good activity, it could be helpful. If I had the disease and was offered plasma therapy I would certainly accept, but I would not take hydroxychloroquine."

Doherty is also very optimistic about herd immunity developing against the SARS-CoV-2 infection.

"We think that (herd immunity) will cut in and have an obvious effect when, say, 60 per cent of people have been infected. Best hope is to boost herd immunity with a vaccine," he stated.

Herd immunity is a form of indirect protection from infectious disease that occurs when a large percentage of a population has become immune to an infection, whether through vaccination or previous infections.

The number of COVID-19 cases have crossed 5.9 million and the fatalities 3,65,000, according to the Johns Hopkins University on Saturday. 

In India, the death toll has risen to 4,971 and the number of cases to 1,73,763, according to the Union Health Ministry on Saturday.

Several states, including Bihar, Uttar Pradesh, Madhya Pradesh, Jharkhand and Chhattisgarh, have reported a rise in number since lockdown norms were relaxed in early May and migrant workers reached home.

In Uttar Pradesh, for instance, the number of infections rose from around 3,000 on May 4 to 6,532 on May 26. Similarly, Bihar’s numbers increased from around 500 to over 2,700 in the period.
