In Germany, a few Muslim refugees convert to Christianity

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.

Jan 30: The death toll rose to 170 in the new virus outbreak in China on Thursday as foreign evacuees from the worst-hit region begin returning home under close observation and world health officials expressed “great concern” that the disease is starting to spread between people outside of China.

Thursday’s figures cover the previous 24 hours and represent an increase of 38 deaths and 1,737 cases for a total of 7,711. Of the new deaths, 37 were in the epicenter of the outbreak in Hubei province and one in the southwestern province of Sichuan.

The news comes as the 195 Americans evacuated from Wuhan, the Hubei province city of 11 million where the outbreak originated, are undergoing three days of testing and monitoring at a Southern California military base to make sure they do not show signs of the virus.

A group of 210 Japanese evacuees from Wuhan landed Thursday at Tokyo’s Haneda airport on a second government chartered flight, according to the foreign ministry. Reports said nine of those aboard the flight showed signs of cough and fever. Three of the 206 Japanese who returned on Wednesday tested positive for the new coronavirus, Prime Minister Shinzo Abe said during a parliamentary session. Two of them showed no symptoms of the disease.

France, New Zealand, Australia and other countries are also pulling out their citizens or making plans to do so.

The World Health Organization emergencies chief said the few cases of human-to-human spread of the virus outside China — in Japan, Germany, Canada and Vietnam — were of “great concern” and were part of the reason the U.N. health agency’s director-general was reconvening a committee of experts on Thursday to assess whether the outbreak should be declared a global emergency.

The new virus has now infected more people in China than were sickened there during the 2002-2003 SARS outbreak.

Dr. Michael Ryan spoke at a news conference in Geneva on Wednesday after returning from a trip to Beijing to meet with Chinese President Xi Jinping and other senior government leaders. He said China was taking “extraordinary measures in the face of an extraordinary challenge” posed by the outbreak.

To date, about 99% of the cases are in China. Ryan estimated the death rate of the new virus at 2%, but said the figure was very preliminary. With fluctuating numbers of cases and deaths, scientists are only able to produce a rough estimate of the fatality rate and it’s likely many milder cases of the virus are being missed.

In comparison, the SARS virus killed about 10% of people who caught it. The new virus is from the coronavirus family, which includes those that can cause the common cold as well as more serious illnesses such as SARS and MERS.

Scientists say there are many questions to be answered about the new virus, including just how easily it spreads and how severe it is.

In a report published Wednesday, Chinese researchers suggested that person-to-person spread among close contacts occurred as early as mid-December.

“Considerable efforts” will be needed to control the spread if this ratio holds up elsewhere, researchers wrote in the report, published in the New England Journal of Medicine.

More than half of the cases in which symptoms began before Jan. 1 were tied to a seafood market, but only 8% of cases after that have been, researchers found. They reported the average incubation period was five days.
