Chinese authorities on Monday set the latest example of strict Coronavirus (COVID-19) measures when it sent several thousand students into quarantine.

More than 10,000 students were required to stay in their dormitory rooms or go to quarantine hotels in the northeastern city of Dalian.

The authorities were reacting to an outbreak among students, with about 60 infections reported across the city, which has a population of more than 6 million, the number of infections stood at more than 200.

The Chinese government is pursuing a strict “zero Covid” policy, including curfews, mass testing, contact tracing, quarantines, and strict entry restrictions.

So far, the rigorous approach has limited the pandemic to smaller outbreaks, which have been brought under control again after a few weeks.
