Twitter suspends over 70 million accounts in 2 months: Washington Post

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.

Washington, May 22: The deadly coronavirus came from China and the US is not going to take it lightly, American President Donald Trump said on Thursday.

"It came from China. We are not happy about it. We just signed a trade deal, the ink wasn't dry and all of the sudden this floated in. We are not going to take it lightly,” Trump said participating in a Listening Session with African-American Leaders in Michigan.

Trump in the last several weeks has been very critical of China's inability to control the spread of the novel coronavirus within its territory. By Thursday more than 94,000 Americans have died due to the coronavirus and over 1.6 million have tested positive.

He has so far not given any indication of the steps that he is contemplating taking against China.

Meanwhile, pressure is building on his administration, mainly from the Republican lawmakers on this.

On Thursday, Senators Ted Cruz and Rick Scott, along Mike Braun, Marsha Blackburn, Joni Ernst, Martha McSally and Tom Cotton, introduced the COVID-19 Vaccine Protection Act to prevent the Chinese Communist Party from stealing or sabotaging American COVID-19 vaccine research.

The bill requires a thorough national security evaluation and clearance by the Department of Homeland Security, the Department of State, and the Federal Bureau of Investigation of all Chinese student visa holders taking part in activities related to COVID-19 vaccine research.

"The same Chinese Communist Party that covered up the coronavirus outbreak also routinely engages in state sponsored theft of intellectual property," Cruz said. "We cannot allow China to steal or interfere with American research and development of a vaccine,” he added.

"Communist China is responsible for the coronavirus pandemic, and their lies and misinformation cost American lives," Scott said.

"We cannot let Communist China off the hook for this, and we absolutely cannot allow Communist China to steal or sabotage any American research efforts related to the Coronavirus vaccine. The COVID-19 Vaccine Protection Act protects American efforts to create a vaccine as we work to end this pandemic," he added.

The COVID-19 Vaccine Protection Act, among others requires an enhanced vetting of nationals of the Chinese nationals in the US as nonimmigrants under F, J, or M student visas to determine if any student visa holders are a national security threat.

Once the review is complete, authorizes Department of Homeland Secretary, in consultation with other agencies, to continuously monitor all nonimmigrant student visa holders (F, M, J) who are Chinese nationals while in the US and are engaged in, or have access to, the research of any potential COVID-19 vaccine or COVID-19 related material.

Republican Whip and Ranking Member of the Select Subcommittee on the Coronavirus Crisis Steve Scalise alleged that China lied to the world on coronavirus.

"During a critical period in December and January, China withheld evidence of the virus: evidence that confirmed human to human transmission of the virus, evidence of the extent of the spread. China refused entry of American and other medical experts from around the world for weeks,” he said.

“And during this time, China hoarded medical supplies like masks, gowns, and other life-saving PPE. Chinese exports of surgical masks, gowns, and gloves were stifled by the Chinese Communist Party during this period. China knew the danger posed by the virus and while they hid the truth, they used the time to stock up on vital medical supplies,” Scalise said.

“While Chinese authorities limited domestic flights from Wuhan to other Chinese cities like Beijing and Shanghai, China's government urged international carriers to maintain their flight schedules — seeding the virus throughout the rest of the world,” he alleged.

Saint Martin's Island, Feb 12: At least 15 women and children drowned and more than 50 others were missing after a boat overloaded with Rohingya refugees sank off southern Bangladesh as it tried to reach Malaysia Tuesday, officials said.

Some 138 people -- mainly women and children -- were packed on a trawler barely 13 metres (40 feet) long, trying to cross the Bay of Bengal, a coast guard spokesman told news agency.

"It sank because of overloading. The boat was meant to carry maximum 50 people. The boat was also loaded with some cargo," another coast guard spokesman, Hamidul Islam, added.

Nearly one million Rohingya live in squalid camps near Bangladesh's border with Myanmar, many fleeing the neighbouring country after a 2017 brutal military crackdown.

With few opportunities for jobs and education in the camps, thousands have tried to reach other countries like Malaysia and Thailand by attempting the hazardous 2,000-kilometre journey.

In the latest incident, 71 people have been rescued including 46 women. Among the dead, 11 were women and the rest children.

Anwara Begum said two of her sons, aged six and seven, drowned in the tragedy.

"We were four of us in the boat... Another child (son, aged 10) is very sick," the 40-year-old told news agency.

Fishermen tipped off the coast guard after they saw survivors swimming and crying for help in the sea.

The boat's keel hit undersea coral in shallow water off Saint Martin's Island, Bangladesh's southernmost territory, before it sank, survivors said.

"We swam in the sea before boats came and rescued us," said survivor Mohammad Hossain, 20.

Coast guard commander Sohel Rana said three survivors, including a Bangladeshi, were detained over human trafficking allegations.

An estimated 25,000 Rohingya left Bangladesh and Myanmar on boats in 2015 trying to get to Thailand, Malaysia and Indonesia. Hundreds drowned when overloaded boats sank.

Begum said her family paid a Bangladeshi trafficker $450 per head to be taken to Malaysia.

"We're first taken to a hill where we stayed for five days. Then they used three small trawlers to take us to a large trawler, which sank," she said.

Shakirul Islam, a migration expert whose group works with Rohingya to raise awareness against trafficking, said desperation in the camps was making refugees want to leave.

"It was a tragedy waiting to happen," he said.

"They just want to get out, and fall victim to traffickers who are very active in the camps."

Islam said in the past two months dozens of Rohingya reported approaches from traffickers to his OKUP migration rights group.

"Human smuggling and trafficking in the Bay of Bengal is particularly difficult to address as it requires concerted effort from multiple states," the Bangladesh head of UN agency the International Organization for Migration, Giorgi Gigauri, told news agency.

"The gaps in coordination are easily exploited by criminal networks."

Since last year, Bangladeshi authorities have picked up over 500 Rohingya from rickety fishing trawlers or coastal villages as they waited to board boats.

Trafficking often increases during the November-March period when the sea is safest for the small trawlers used by traffickers.

Bangladesh and Myanmar signed a repatriation deal to send back some Rohingya to their homeland, but none have agreed to return because of safety fears.

The charity Save the Children called on Myanmar to "take all necessary steps to ensure the Rohingya community can return to their homes in a safe and dignified manner".

"The tragic drowning of women and children... should be a wake-up call for us all," the group's Athena Rayburn said in a statement.
