Pompeo's remarks on terrorism trigger controversy

Melbourne, Apr 10: Scientists have identified six drug candidates from more than 10,000 compounds that may help treat COVID-19.

The research, published in the journal Nature, tested the efficacy of approved drugs, drug candidates in clinical trials and other compounds.

"Currently there are no targeted therapeutics or effective treatment options for COVID-19," said Professor Luke Guddat from the University of Queensland in Australia.

"In order to rapidly discover lead compounds for clinical use, we initiated a programme of high-throughput drug screening, both in laboratories and also using the latest computer software to predict how different drugs bind to the virus," Guddat said.

The project targeted the main COVID-19 virus enzyme, known as the main protease or Mpro, which plays a pivotal role in mediating viral replication, the researchers said.

This makes it an attractive drug target for this virus, and as people don't naturally have this enzyme, compounds that target it are likely to have low toxicity, they said.

"We add the drugs directly to the enzyme or to cell cultures growing the virus and assess how much of each compound is required to stop the enzyme from working or to kill the virus. If the amount is small, then we have a promising compound for further studies," said Guddat.

After assaying thousands of drugs, researchers found of the six that appear to be effective in inhibiting the enzyme, one is of particular interest.

"We're particularly looking at several leads that have been subjected to clinical trials including for the prevention and treatment of various disorders such as cardiovascular diseases, arthritis, stroke, atherosclerosis and cancer," Guddat said.

Researchers said compounds that are already along the pipeline to drug discovery are preferred, as they can be further tested as antivirals at an accelerated rate compared to new drug leads that would have to go through this process from scratch.

"With continued and up-scaled efforts we are optimistic that new candidates can enter the COVID-19 drug discovery pipeline in the near future," Guddat said.

Beijing, Feb 24: The lockdown of Guo Jing's neighbourhood in Wuhan -- the city at the heart of China's new coronavirus epidemic -- came suddenly and without warning.

Unable to go out, the 29-year-old is now sealed inside her compound where she has to depend on online group-buying services to get food.

"Living for at least another month isn't an issue," Guo told news agency, explaining that she had her own stash of pickled vegetables and salted eggs.

But what scares her most is the lack of control -- first, the entire city was sealed off, and then residents were limited to exiting their compound once every three days.

Now even that has been taken away.

Guo is among some 11 million residents in Wuhan, a city in central Hubei province that has been under effective quarantine since January 23 as Chinese authorities race to contain the epidemic.

Since then, its people have faced a number of tightening controls over daily life as the death toll from the virus swelled to over 2,500 in China alone.

But the new rules this month barring residents from leaving their neighbourhoods are the most restrictive yet -- and for some, threaten their livelihoods.

"I still don't know where to buy things once we've finished eating what we have at home," said Pan Hongsheng, who lives with his wife and two children.

Some neighbourhoods have organised group-buying services, where supermarkets deliver orders in bulk.

But in Pan's community, "no one cares".

"The three-year-old doesn't even have any milk powder left," Pan told news agency, adding that he has been unable to send medicine to his in-laws -- both in their eighties -- as they live in a different area.

"I feel like a refugee."

The "closed management of neighbourhoods is bound to bring some inconvenience to the lives of the people", Qian Yuankun, vice secretary of Hubei's Communist Party committee, said at a press briefing last week.

Authorities on Monday allowed healthy non-residents of the city to leave if they never had contact with patients, but restrictions remained on those who live in Wuhan.

Demand for group-buying food delivery services has rocketed with the new restrictions, with supermarkets and neighbourhood committees scrambling to fill orders.

Most group-buying services operate through Chinese messaging app WeChat, which has ad-hoc chat groups for meat, vegetables, milk -- even "hot dry noodles", a famous Wuhan dish.

More sophisticated shops and compounds have their own mini-app inside WeChat, where residents can choose packages priced by weight before orders are sent in bulk to grocery stores.

In Guo's neighbourhood, for instance, a 6.5-kilogramme (14.3-pound) set of five vegetables, including potatoes and baby cabbage, costs 50 yuan ($7.11).

"You have no way to choose what you like to eat," Guo said. "You cannot have personal preferences anymore."

The group-buying model is also more difficult for smaller communities to adopt, as supermarkets have minimum order requirements for delivery.

"To be honest, there's nothing we can do," said Yang Nan, manager of Lao Cun Zhang supermarket, which requires a minimum of 30 orders.

"We only have four cars," she said, explaining that the store did not have the staff to handle smaller orders.

Another supermarket told AFP it capped its daily delivery load to 1,000 orders per day.

"Hiring staff is difficult," said Wang Xiuwen, who works at the store's logistics division, adding that they are wary about hiring too many outsiders for fear of infection.

Closing off communities has split the city into silos, with different neighbourhoods rolling out controls of varying intensity.

In some compounds, residents have easier access to food -- albeit a smaller selection than normal -- and one woman said her family pays delivery drivers to run grocery errands.

Her compound has not been sealed off either, the 24-year-old told AFP under condition of anonymity, though they are limited to one person leaving at a time.

Some districts have implemented their own rules, such as prohibiting supermarkets from selling to individuals, forcing neighbourhoods to buy in bulk or not at all.

"In the neighbourhood where I live, the reality is really terrible," said David Dai, who is based on the outskirts of Wuhan.

Though his apartment complex has organised group-buying, Dai said residents were unhappy with price and quality.

"A lot of tomatoes, a lot of onions -- they were already rotten," he told , estimating over a third of the food had to be thrown away.

His family must "totally depend" on themselves, added the 49-year-old, who has resorted to saving and drying turnip skins to add nutrients to future meals.

The uncertainty of not knowing when the controls will be lifted is also frustrating, said Ma Chen, a man in his 30s who lives alone.

"I have no way of knowing how much (food) I should buy."

United Nations, May 8: UN Secretary-General Antonio Guterres said Friday the coronavirus pandemic keeps unleashing a tsunami of hate and xenophobia, scapegoating and scare-mongering. 

The UN chief said anti-foreigner sentiment has surged online and in the streets, anti-Semitic conspiracy theories have spread, and COVID-19-related anti-Muslim attacks have occurred. 

Guterres said migrants and refugees have been vilified as a source of the virus -- and then denied access to medical treatment. 

With older persons among the most vulnerable, contemptible memes have emerged suggesting they are also the most expendable, he said. 

And journalists, whistleblowers, health professionals, aid workers and human rights defenders are being targeted simply for doing their jobs. 

Guterres appealed for an all-out effort to end hate speech globally. The secretary-general called on political leaders to show solidarity with all people, on educational institutions to focus on digital literacy at a time when extremists are seeking to prey on captive and potentially despairing audiences. 

He called on the media, especially social media, to remove racist, misogynist and other harmful content, on civil society to strengthen their outreach to vulnerable people, and on religious figures to serve as models of mutual respect. 

And I ask everyone, everywhere, to stand up against hate, treat each other with dignity and take every opportunity to spread kindness, Guterres said.

The secretary-general stressed that COVID-19 does not care who we are, where we live, what we believe or about any other distinction. His global appeal to address and counter COVID-19-related hate speech follows his April 23 message calling the coronarivus pandemic a human crisis that is fast becoming a human rights crisis. 

Guterres said then that the pandemic has seen disproportionate effects on certain communities, the rise of hate speech, the targeting of vulnerable groups, and the risks of heavy-handed security responses undermining the health response. 

With rising ethno-nationalism, populism, authoritarianism and a push back against human rights in some countries, the crisis can provide a pretext to adopt repressive measures for purposes unrelated to the pandemic, he warned.

In February, Guterres issued a call to action to countries, businesses and people to help renew and revive human rights across the globe, laying out a seven-point plan amid concerns about climate change, conflict and repression.
