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.

Nairobi, Mar 14: Kenya and Ethiopia on Friday announced their first confirmed cases of coronavirus, as East Africa, which has so far been unscathed by the global pandemic, scaled up emergency measures to contain its spread.

In Kenya, a 27-year-old Kenyan woman tested positive for the virus on Thursday in Nairobi, a week after returning from the United States via London.

She was in a stable condition and recovering, Health Minister Mutahi Kagwe told reporters.

"We wish to assure all Kenyans that the government will use all the resources available to fight coronavirus," he said, as the government rolled out a raft of new containment measures.

The government had traced all the contacts of the patient since she arrived back in Kenya on March 5, he said.

"At the moment, there is absolutely no need for panic and worry," he said.

Kenya, with a population of 50 million people, saw a spree of panic buying among the middle-class in Nairobi supermarkets, in the wake of the announcement.

Meanwhile Ethiopia, Africa's second most populous nation with over 100 million people, said a 48-year-old Japanese man who had arrived in the country on March 4 from Burkina Faso was confirmed to have contracted the virus.

"He is undergoing medical follow-up and is in a stable condition. Those who have been in contact with this person are being traced and quarantined," the health ministry said in a statement.

Burkina Faso only confirmed its first case on Tuesday -- a couple returning from France -- and the Japanese patient had been in that country since February 24.

Ethiopian Health Minister Lia Tadesse said three other patients were in isolation.

Ethiopia becomes the 15 country in Africa with a confirmed case of the virus that has swept the globe, infecting more than 130,000 people and killing nearly 5,000 since it first emerged in China.

But to date the continent has been spared the worst of the pandemic.

Only five people have succumbed to coronavirus so far -- all in north Africa -- with the sub-Saharan region recording no deaths and very low numbers of confirmed cases.

But countries in East Africa -- which until the positive case in Kenya, had only recorded negative test results -- have been taking precautions.

Some flights have been restricted, with Kenya Airways suspending its route to Rome, and charter flights from Italy to the Kenyan coast on hold.

It has also suspended international conferences, a top earner in Nairobi, a hub for such events in the region, and non-essential travel abroad for politicians.

The government announced more expansive restrictions on Friday, including a temporary ban on major public gatherings, prison visits and activities between schools.

Other countries in the region have been rolling out their own measures.

In Rwanda, which shares a border with the Democratic Republic of Congo, which has confirmed cases, washing basins with soap and sanitiser have been placed on streets for commuters to use before boarding buses.

Authorities in Kigali, the capital, have also banned concerts, rallies and trade fairs -- although like in Kenya and Uganda, church services have been proceeding and bars, restaurants and entertainment precincts remain open.

Neighbouring Burundi, meanwhile, has quarantined 34 people in a hotel in Bujumbura as a precaution.

Uganda has ordered that visitors from a number of affected countries self quarantine for 14 days, or consider simply not visiting at all.

South Sudan's health ministry said meanwhile that it was "temporarily suspending direct flights between South Sudan and all affected countries".

Kagwe, the Kenyan health minister, also addressed a rumour circulating on social media that people with black skin cannot contract the virus.

"I would like to disabuse that notion. The lady (confirmed with coronavirus in Kenya) is an African, like you and I," he said.

Minneapolis, Jun 2: An official autopsy released Monday ruled that George Floyd, the African-American man whose death at police hands set off unrest across the United States, died in a homicide involving "neck compression".

George, 46, died of "cardiopulmonary arrest complicating law enforcement subdual, restraint, and neck compression," and the manner of death was "homicide," the Hennepin County Medical Examiner in Minneapolis said in a statement.

Floyd's other significant health conditions were listed as "arteriosclerotic and hypertensive heart disease; fentanyl intoxication; recent methamphetamine use."

The statement added that the "manner of death is not a legal determination of culpability or intent."

It emphasized that under Minnesota state law "the Medical Examiner is a neutral and independent office and is separate and distinct from any prosecutorial authority or law enforcement agency."
