Chinese youngsters in the city where the global coronavirus was first detected late last year began filing back into classrooms on Wednesday, wearing masks and walking in single file past thermal scanners. Senior school students in 121 institutions were back in front of chalkboards and digital displays for the first time since their city – the ground zero of the coronavirus pandemic – shut down in January. "School is finally reopening!" posted one user of Weibo, China's Twitter-like short messaging platform. "This is the first time that I'm so happy to go back to school, although I have to sit a monthly examination on the 8th." Teenagers sat at individual desks spaced a metre apart, seeing their teachers in the flesh after months of distance learning. Wednesday's back-to-school was the latest step in a gradual normalising of life in Wuhan and surrounding Hubei province, where the coronavirus is believed to have emerged late last year before spreading around the world. Only the province's oldest students were present – seniors who are due to take the make-or-break university entrance exams. Return dates have not yet been confirmed for junior and middle school students. Officials in Wuhan say students and staff must all have virus tests before going back to school, and campuses have been disinfected and cleaned. In preparation for reopening, some schools spaced out their desks and organised smaller class sizes, according to local media. Thermal scanners greeted everyone walking through school gates and anyone with a high temperature was not allowed in. State-run China Daily said some places arranged staggered arrival times for teachers and students. Elsewhere in China, schools that have been closed or online-only since January began gradually reopening last month, with Beijing and Shanghai letting some students return last week. China's major cities are gradually returning to normal after imposing strict travel restrictions and closing huge swathes of the economy to control the spread of the virus. In recent months infections nationwide have dwindled, and there have been no new cases reported in Hubei province for over a month. Over a five-day holiday at the start of the month, there were 115 million domestic trips, with many tourist sites reopening – although with limited attendance. Shanghai Disneyland will reopen next week, the entertainment giant said on Tuesday, with enhanced safety measures including temperature screening and social distancing. However, foreigners are still banned from entering the country as China works to contain infections being brought in from overseas. Chinese nationals returning home must undergo 14 days of quarantine.
