BEIJING: As frontline workers at China’s international airports have recently emerged as particularly vulnerable to contracting the novel coronavirus, officials and experts have required stricter isolation and more frequent testing of them, while considering providing booster shots to enhance their immunity.
An outbreak in Nanjing, Jiangsu province, that spread to more than 10 provincial-level regions has been traced to nine airport workers in the city who cleaned a plane arriving from Russia on June 10.
