Taipei, Jan. 5 (CNA) China's COVID-19 pandemic is still peaking, with about 20 percent of arrivals from China at Taiwan airports testing positive for the coronavirus, according to the Central Epidemic Control Center (CECC) on Thursday.However, the CECC does not plan to use the electronic fence system to monitor arrivals from China for now, nor will it open the border to Chinese tourists soon, said CECC head Victor Wang (王必勝) at the press conference.Meanwhile, Wang said that throughout January, those on flights from the Chinese cities of Beijing, Shanghai, Chengdu, and Xiamen -- which all currently have direct flights to Taiwan -- will be subjected to a saliva-based polymerase chain reaction (PCR) test at the airport when they arrive in Taiwan.As for those from Hong Kong and Macau, they do not have to take the PCR test upon arrival, but will have to provide a negative result of a PCR test done within 48 hours prior to their boarding, Wang said.With the Lunar New Year around the corner, Wang reminded the public to prepare a number of face masks and rapid test kits in advance, as most pharmacies will be closed during the holiday."
