A construction team from China helped Serbia build a laboratory for boosting COVID-19 testing. The members of the Chinese team, with an average age of 29, are all experienced in fighting the disease, having been on the frontline during the outbreak in Wuhan. The laboratory, named "Huoyan," is equipped with advanced technologies that help with various tasks, such as the automatic extraction of nucleic acid. Nearly 2,000 samples per day on average have been tested since the facility was put into use on April 20.
