53 arrested as Hong Kong marks first anniversary of pro-democracy protests

Hundreds of thousands of people across the world are joining the anti-racism demonstrations days after the killing of George Floyd in United Sates. 

The protests are being held in cities including London, Manchester, Cardiff, Leicester and Sheffield.

Demonstrators attached ropes to the statue of Edward Colston before pulling it down to cheers and roars of approval from the crowd. Images on social media show the statue was eventually rolled into the city's harbour. 

It was not the only statue targeted on Sunday. In Brussels, protesters clambered onto the statue of former King Leopold II and chanted "reparations".

The word "shame" was also graffitied on the monument, reference perhaps to the fact that Leopold is said to have reigned over the mass death of 10 million Congolese.

In London, thousands of people congregated around the US embassy for the second day running.

While protests were mainly peaceful, there were some scuffles near the office of Prime Minister Boris Johnson and outside the Parliament gates.

In Hong Kong, about 20 people staged a rally in solidarity with the Black Lives Matter movement on Sunday outside the US consulate in the semi-autonomous Chinese city.

"It's a global issue," Quinland Anderson, a 28-year-old British citizen living in Hong Kong, told The Associated Press news agency.

"We have to remind ourselves despite all we see going on in the US and in the other parts of the world, Black lives do indeed matter."

Several dozen demonstrators took part in a Black Lives Matter protest held in Tel Aviv's central Rabin Square.

A rally in Rome's sprawling People's Square was noisy but peaceful, with the majority of protesters wearing masks to protect against coronavirus. Participants listened to speeches and held up handmade placards saying "Black Lives Matter" and "It's a White Problem".

In Spain, several thousand people gathered on the streets of Barcelona and at the US embassy in Madrid.

Many in Madrid carried homemade signs reading "Black Lives Matter", "Human rights for all" and "Silence is pro-racist".

"We are not only doing this for our brother George Floyd," said Thimbo Samb, a spokesman for the group that organised the events in Spain mainly through social media. "Here in Europe, in Spain, where we live, we work, we sleep and pay taxes, we also suffer racism."

May 5: Global coronavirus deaths reached 250,000 on Monday after recorded infections topped 3.5 million, a news agency tally of official government data showed, although the rate of fatalities has slowed.

North America and European countries accounted for most of the new deaths and cases reported in recent days, but numbers were rising from smaller bases in Latin America, Africa and Russia.

Globally, there were 3,062 new deaths and 61,923 new cases over the past 24 hours, taking total cases to 3.58 million.

That easily exceeds the estimated 140,000 deaths worldwide in 2018 caused by measles, and compares with around 3 million to 5 million cases of severe illness caused annually by seasonal influenza, according to the World Health Organization (WHO).

While the current trajectory of COVID-19 falls far short of the 1918 Spanish flu, which infected an estimated 500 million people, killing at least 10% of patients, experts worry the available data is underplaying the true impact of the pandemic.

The concerns come as several countries begin to ease strict lockdowns that have been credited with helping contain the spread of the virus.

"We could easily have a second or a third wave because a lot of places aren't immune," Peter Collignon, an infectious diseases physician and microbiologist at Canberra Hospital, told Reuters. He noted the world was well short of herd immunity, which requires around 60% of the population to have recovered from the disease.

The first death linked to COVID-19 was reported on Jan. 10 in Wuhan, China after the coronavirus first emerged there in December. Global fatalities grew at a rate of 1-2% in recent days, down from 14% on March 21, according to the Reuters data.

DEATH RATE ANOMALIES

Mortality rates from recorded infections vary greatly from country to country.

Collignon said any country with a mortality rate of more than 2% almost certainly had underreported case numbers. Health experts fear those ratios could worsen in regions and countries less prepared to deal with the health crisis.

"If your mortality rate is higher than 2%, you've missed a lot of cases," he said, noting that countries overwhelmed by the outbreak were less likely to conduct testing in the community and record deaths outside of hospitals.

In the United States, around half the country's state governors partially reopened their economies over the weekend, while others, including New York Governor Andrew Cuomo, declared the move was premature.

In Britain, Prime Minister Boris Johnson, who battled COVID-19 last month, has said the country was over the peak but it was still too early to relax lockdown measures.

Even in countries where the suppression of the disease has been considered successful, such as Australia and New Zealand which have recorded low daily rates of new infections for weeks, officials have been cautious.

Australian Prime Minister Scott Morrison has predicated a full lifting of curbs on widespread public adoption of a mobile phone tracking app and increased testing levels.

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.
