CNA file photo Taipei, Feb. 1 (CNA) The Central Epidemic Command Center (CECC) will expand the scope of COVID-19 testing later this week to cover all people working at Taoyuan General Hospital -- the epicenter of a cluster infection -- to make sure no coronavirus patient is missed. Health and Welfare Minister Chen Shih-chung (陳時中), who heads the CECC, said Monday that since the cluster infection broke out at the hospital on Jan. 12, 4,337 people have undergone or are still undergoing 14-day quarantines. Among them, 1,820 have tested negative for COVID-19 as testing continues. The 4,337 individuals include contacts of confirmed COVID-19 cases, hospital employees, patients who were discharged from the hospital last month, and their close contacts.
