Stringent contact tracing and quarantine measures are more effective than locking down cities in containing the spread of COVID-19, former vice president Chen Chien-jen (陳建仁) told CNN on Sunday.
Chen shared Taiwan’s experience in combating SAR-CoV-2 during an interview with CNN host Fareed Zakaria on his weekly GPS program.
The Johns Hopkins-trained epidemiologist said that unlike the US, Taiwan did not lock down its cities.
“City lockdown is not a good way. The very careful contact tracing and very stringent quarantine of close contacts are the best ways to contain the COVID-19,” he said.
Taiwan did not conduct widespread mass testing either, he said.
Instead, it tested people who showed possible symptoms of COVID-19 and then conducted contact tracing and tracking of those who might have come in contact with them, he added.
“We considered it more efficient and also more effective,” he said.
Chen highlighted the importance of implementing 14-day home quarantine for those who had come into contact with confirmed cases.
About 250,000 people have been quarantined in Taiwan and 99.5 percent followed the quarantine guidelines, while the remaining few who broke the rules received penalties, Chen said.
“I always say that we have sacrificed 250,000 people’s freedom for 14 days. But through this kind of home quarantine we can assure that 23 million people in Taiwan can work normally, go to school normally and live normally,” he said.
In this way, Taiwan contained the outbreak and reduce the effect of the global pandemic on the economy, Chen said.
Asked if he thought China deceived the world at the beginning of the outbreak, Chen said that the world would not have suffered as much as it did if China reported the outbreak to the WHO at an early stage.
“If the WHO received the information and helped China contain COVID-19 in Wuhan in December [last year], I think the disease [could have been contained] there quite well,” he said.
Wuhan authorities at the early stage of the outbreak treated only severe cases in hospitals and ignored mild ones, resulting in the spread of the virus from the city to other parts of China and the world, Chen said.
Asked to predict how the pandemic might play out in the coming months, Chen said the first wave of COVID-19 “has not gone at all,” given that new confirmed cases remained high around the globe.
“It is still going on, so we have to be very careful,” he said.
FEW REMAIN: Conservationists tried to stop the demolition, but to no avail, and the owner cannot be fined, as the structure was not listed as a historical building One of the few remaining Japanese colonial-era granaries in Taiwan was dismantled by its owner on Friday, prompting outrage from conservationists. The granary, which was at No. 16, Lane 11, Hangzhou S Rd Sec 1 in Taipei, belonged to Taiwan Takushoku Corp during the colonial era, conservationist Chang Wan-lin (張琬琳) said, adding that she and others had been collecting information to reapply to have the building protected as a historical structure.

TROUBLEMAKER: The missiles, capable of striking up to 2,000km away, would likely be used to deter other nations from coming to Taiwan’s aid, a legislator said The Chinese People’s Liberation Army (PLA) has reportedly deployed advanced hypersonic missiles along China’s southeast coast, which Taiwan’s missile defense system might have difficulty intercepting, an analyst said yesterday. Citing an unnamed military source, the South China Morning Post said that the missile bases on the coasts of China’s Fujian and Zhejiang provinces have been upgraded and are stocked with DF-17 missiles, equipped with hypersonic glide vehicles. “The DF-17 hypersonic missile will gradually replace the old DF-11s and DF-15s that were deployed in the southeast region for decades,” said the source, who requested anonymity because of the sensitivity of the topic. “The
AIR CONTROL INCIDENT: The Hong Kong side said it ‘cannot accept this aircraft,’ ordering it to ascend to an unsafe altitude and forcing it to return to Kaohsiung The Civil Aeronautics Administration (CAA) on Friday disclosed a full transcript of the communications between Taiwanese and Hong Kong air traffic controllers, rebutting the latter’s claim that a Taiwanese plane had voluntarily abandoned its flight path. Hong Kong denied permission for the plane to proceed to the disputed Pratas Islands (Dongsha Islands, 東沙群島), which are claimed by both Taiwan and China, the CAA said. The incident happened on Thursday when a civil aircraft chartered by the military was advised by Hong Kong air traffic controllers to not enter the airspace over a group of islands in the South China Sea
