New imported cases and foreign nationals testing positive after returning home from Taiwan has sparked public debate on whether the government should expand COVID-19 testing to all inbound travelers to better detect asymptomatic cases locally, he said. National Taiwan University College of Public Health vice dean Tony Chen presents his policy proposals yesterday in Taipei. If travelers are tested upon arrival, quarantined for five days and tested again, more than 99 percent of cases would also have be detected, he said. Testing all travelers upon arrival might cause those who test negative to let down their guard during quarantine, he said. Strictly implementing the current policy of a 14-day quarantine and an additional seven-day self-health management would be a better method of preventing imported cases causing local infections, Fang said, adding that mask wearing remains equally important.
