Gunman take several people hostage at cafe in Sydney

As the deadly coronavirus has spread worldwide, it has carried with it xenophobia -- and Asian communities around the world are finding themselves subject to suspicion and fear.

When a patient on Australia's Gold Coast refused to shake the hand of her surgeon Rhea Liang, citing the virus that has killed hundreds, the medic's first response was shock.

But after tweeting about the incident and receiving a flood of responses, the respected doctor learned her experience was all too common.

There has been a spike in reports of anti-Chinese rhetoric directed at people of Asian origin, regardless of whether they have ever visited the centre of the epidemic or been in contact with the virus.

Chinese tourists have reportedly been spat at in the Italian city of Venice, a family in Turin was accused of carrying the disease, and mothers in Milan have used social media to call for children to be kept away from Chinese classmates.

In Canada, a white man was filmed telling a Chinese-Canadian woman "you dropped your coronavirus" in the parking lot of a local mall.

In Malaysia, a petition to "bar Chinese people from entering our beloved country" received almost 500,000 signatures in one week.

The incidents are part of what the Australasian College for Emergency Medicine has described as "misinformation" which it says is fuelling "racial profiling" where "deeply distressing assumptions are being made about 'Chinese' or 'Asian-looking' people." Disease has long been accompanied by suspicions of foreigners -- from Irish immigrants being targeted in the Typhoid Mary panic of 1900s America to Nepali peacekeepers being accused of bringing cholera to earthquake-struck Haiti in the last decade.

"It's a common phenomenon," said Rob Grenfell, director of health and biosecurity for Australia's science and research agency CSIRO.

"With outbreaks and epidemics along human history, we've always tried to vilify certain subsets of the population," he said, comparing the behaviour to 1300s plague-ridden medieval Europe, where foreigners and religious groups were often blamed.

"Sure it emerged in China," he said of the coronavirus, "but that's no reason to actually vilify Chinese people." In a commentary for the British Medical Journal, doctor Abraar Karan warned this behaviour could discourage people with symptoms from coming forward.

Claire Hooker, a health lecturer at the University of Sydney, said the responses from governments may have compounded prejudice.

The World Health Organisation has warned against "measures that unnecessarily interfere with international travel and trade", but this has not stopped scores of countries from introducing travel bans.

The tiny Pacific nation of Micronesia has banned its citizens from visiting mainland China altogether.

"Travel bans respond largely to people's fears," said Hooker, and while sometimes warranted, they often "have the effect of cementing an association between Chinese people and scary viruses".

Abbey Shi, a Shanghai-born student in Sydney, said the attitude shown by some of her peers has "become almost an attack on students who are Chinese".

While Australia's conservative government has banished its citizens returning from Wuhan -- the central Chinese city at the epicentre of the virus -- to a remote island for quarantine, thousands of students still stuck in China risk their studies being torpedoed.

"Right now it looks like they have to miss the semester's start and potentially the whole year, because of the way the courses are set up," Shi said.

According to Hooker, studies in Toronto on the impact of Severe Acute Respiratory Syndrome, or SARS -- another global coronavirus outbreak in 2002 -- showed the impact of xenophobic sentiment often lasted much longer than the public health scare.

"While there may be a cessation of direct forms of racism as news about the disease dies down, it takes quite a bit of time for economic recovery and people continue to feel unsafe," she said.

People may not rush back to Chinese businesses or restaurants, and may even heed some of the more outlandish viral social media disinformation -- such as one popular post imploring people to avoid eating noodles for their own safety.

"In one sense you might think the effects lasted from the last coronavirus to this one because the representation as China being a place where diseases come from has been persistent," Hooker said.

Washington, Jun 6: Washington mayor Muriel Bowser on Friday renamed an area near the White House that has become the epicenter of anti-racism protests over the past week "Black Lives Matter Plaza" -- unveiling a giant street mural.

But in so doing, the African-American mayor piqued the ire of the very movement she was supporting, as well as of President Donald Trump.

The protests are focused on the May 25 death in Minneapolis of 46-year-old black man George Floyd while in police custody. A white officer kneeled on his neck until he lost consciousness.

That officer and three others are now in custody and facing charges -- second-degree murder for the kneeling officer, and aiding and abetting that crime for his colleagues.

Just north of the White House, the words BLACK LIVES MATTER were painted in huge yellow letters along the street leading to the presidential mansion, along with the symbol from the DC flag.

"The section of 16th street in front of the White House is now officially 'Black Lives Matter Plaza'," Bowser tweeted.

A city worker put up a new street sign with the name.

"Determination to make America the land it ought to be," she said on Twitter.

The corner of 16th and H is significant -- in a controversial incident on Monday, peaceful protesters gathered there were dispersed with tear gas.

Shortly afterwards, Trump walked from the White House to a nearby church for a photo op, during which he held the Bible in his hand.

"There was a dispute this week about whose street this is. Mayor Bowser wanted to make it abundantly clear that this is DC's street and to honor demonstrators" who protested on Monday, her chief of staff John Falcicchio tweeted.

Rose Jaffe, one of the artists in the collective that painted the BLACK LIVES MATTER sign, told AFP it was "about reclaiming the streets of DC."

But she added that Bowser "has to do more than just a photo-op -- she must carry on when this is washed away" on issues like police accountability.

Stars Like LeBron James praised her move on Twitter, but the local chapter of the Black Lives Movement balked, calling the mural a "performative distraction from real policy changes."

"This is to appease white liberals while ignoring our demands," it said on Twitter, saying Bowser had "consistently been on the wrong side" of the movement.

'We are well equipped'

The US government deployed a significant contingent of federal officers and National Guard troops from other states -- many of them not wearing any identifying garb or badges -- to handle protests in Washington.

Bowser had called up the local Guardsmen but the Justice Department moved to take partial control of peacekeeping, with Guard troops from as far away as Utah brought in.

In a letter to Trump dated Thursday and tweeted early Friday, Bowser called for "all extraordinary federal law enforcement and military presence" to be removed.

She said their deployment was "inflaming demonstrators and adding to the grievances of those who, by and large, are peacefully protesting for change and for reforms to the racist and broken systems that are killing black Americans."

"These additional, unidentified units are operating outside of established chains of command," she added.

"We are well equipped to handle large demonstrations and First Amendment activities," including the right to assemble, Bowser said.

Trump reiterated on Friday that authorities need to "dominate the streets," and has been unapologetic about the deployment of forces.

And on Twitter, he lashed out at Bowser, calling her "incompetent" and saying the National Guard had saved her from "great embarrassment."

Senator Mike Lee of Utah accused Bowser of evicting Utah National Guard members from area hotels.

She replied: "DC residents cannot pay their hotel bills. The Army can clear that up with the hotel today, and we are willing to help."

UN, May 26: Countries could see a "second peak" of coronavirus cases during the first wave of the pandemic if lockdown restrictions were lifted too soon, the World Health Organization (WHO) has warned.

Mike Ryan, the WHO's head of emergencies, told a briefing on Monday that the world was "right in the middle of the first wave", the BBC reported.

He said because the disease was "still on the way up", countries need to be aware that "the disease can jump up at any time".

"We cannot make assumptions that just because the disease is on the way down now that it's going to keep going down," Ryan said.

There would be a number of months to prepare for a second peak, he added.

The stark warning comes as countries around the world start to gradually ease lockdown restrictions, allowing shops to reopen and larger groups of people to gather.

Experts have said that without a vaccine to give people immunity, infections could increase again when social-distancing measures are relaxed.

Ryan said countries where cases are declining should be using this time to develop effective trace-and-test regimes to "ensure that we continue on a downwards trajectory and we don't have an immediate second peak".

Also on Monday, Tedros Adhanom Ghebreyesus, WHO Director-General, said that a clinical trial of hydroxychloroquine (HCQ) on COVID-19 patients has come to "a temporary pause", while the safety data of the the anti-malaria drug was being reviewed.

According to the WHO chief, The Lancet medical journal on May 22 had published an observational study on HCQ and chloroquine and its effects on COVID-19 patients that have been hospitalized, reports Xinhua news agency.

The authors of the study reported that among patients receiving the drug, when used alone or with a macrolide, they estimated a higher mortality rate.

"The Executive Group of the Solidarity Trial, representing 10 of the participating countries, met on Saturday (May 23) and has agreed to review a comprehensive analysis and critical appraisal of all evidence available globally," Tedros said in a virtual press conference.

The developments come as the total number of global COVID-19 cases has increased to 5,508,904, with 346,508 deaths, according to the Johns Hopkins University.
