“Right now, public opinion in China is very unfriendly towards Chinese overseas students, and quarantine facilities there are mixed,” said Hestia Zhang, a master’s student at Yale University.

She has decided to stay in self-isolation on campus rather than go back, despite the United States now accounting for almost a quarter of reported global infections.

“There are also a lot of risks on the journey home, so I might as well stay here and wait it out,” she told AFP.

Meanwhile Cathy, who landed in China on Tuesday morning, is resigned to the fact that she may encounter prejudice. Using her English name to conceal her identity, she said she had “no choice but to bear it”.

Nearly half of China’s 800 imported virus cases are overseas students.

Most returnees need to spend two weeks in isolation, and a widely shared video of a returned student who tried to escape her quarantine accommodation in the city of Qingdao has prompted outrage online.
