The Central Epidemic Command Center (CECC) yesterday said that it would not ease border restrictions in the short term, as the COVID-19 pandemic is still in a dangerous situation globally, reiterating that mass testing is not necessary in Taiwan at this time.
Minister of Health and Welfare Chen Shih-chung (陳時中), who heads the center, said that no new cases of COVID-19 were confirmed in the nation yesterday, so the number of confirmed cases remains at 467, of whom 441 have been released from isolated treatment, while 19 remain hospitalized.
As the CECC reported nine imported cases on Monday and Tuesday, Chung Shan Medical University Hospital Pediatric Emergency department director Hsieh Tsung-hsueh (謝宗學) on Tuesday said on Facebook that many in Taiwan are not aware of the “tidal wave” of COVID-19 outbreaks in nearby countries and how they could affect Taiwan.

“There is indeed a ‘tidal wave,’ but it has not struck us yet,” Chen said yesterday, adding that everyone in Taiwan should be aware that the global COVID-19 situation is getting worse, and the number of confirmed cases worldwide has exceeded 16 million, including more than 660,000 deaths.
More than 300 imported cases were reported in Taiwan from the middle of March to early April, but the global COVID-19 situation has worsened since then, so it is inevitable to have some imported, he said.
The CECC would not ease border restrictions in the near term, and would continue to observe the global situation, Chen said, adding that although local communities in Taiwan are relatively safe, everyone should still practice personal protective measures to reduce the risk of local infections to a minimum.
Regarding a Thai migrant worker who tested positive for COVID-19 after returning to Bangkok from Taiwan on Tuesday last week, Chen said the center tested 189 people who have come into close contact with or might have had direct exposure to the man, all of which came out negative.
“The migrant worker tested ‘weak-positive’ for COVID-19, so we have contacted the Thai authority to ask if it would conduct a second test for clarification,” he said.
Centers for Disease Control (CDC) Deputy Director-General Chuang Jen-hsiang (莊人祥), who is also CECC spokesperson, said the man visited a clothing store on July 18 and attended a farewell party on July 19 before returning to Thailand, adding that the local health department would continue to trace his contacts.
Chuang said that the center also identified 43 Thai workers who experienced diarrhea or respiratory symptoms last month and this month, and sought treatment at medical facilities, which 18 Thai colleagues of the infected worker had visited in the past few months, and would ask them to undergo reverse transcription-polymerase chain reaction (RT-PCR) and antibody testing.
While many have suggested that the center conduct mass testing to find potential asymptomatic cases in Taiwan, the current policy of mandatory 14-day isolation or quarantine and an additional seven-day self-health management for all people entering the nation is effective enough, Chen said.
The RT-PCR test is more precise in detecting positive cases, but the timing of the test is also important, as the test might fail to detect infections during the incubation period, he said.
The 14-day isolation or quarantine is necessary, as infected people might develop symptoms and become more detectable through tests during the period, Chen said, adding that in asymptomatic cases the viral load usually falls to a level so low that the patient is unlikely to infect other people after 14 days, Chen said.
He said the current policy puts emphasis on the 14-day isolation or quarantine period to increase testing precision and separate potential infected patients from the local community, but allowing people to return to the local communities after testing negative in mass testing might increase the risk of local infections.
Taiwan is to commence mass production of the Tien Kung (天弓, “Sky Bow”) III, IV and V missiles by the second quarter of this year if the legislature approves the government’s NT$1.25 trillion (US$39.78 billion) special defense budget, an official said yesterday. Commenting on condition of anonymity, a defense official with knowledge of the matter said that the advanced systems are expected to provide crucial capabilities against ballistic and cruise missiles for the proposed “T-Dome,” an advanced, multi-layered air defense network. The Tien Kung III is an air defense missile with a maximum interception altitude of 35km. The Tien Kung IV and V
The disruption of 941 flights in and out of Taiwan due to China’s large-scale military exercises was no accident, but rather the result of a “quasi-blockade” used to simulate creating the air and sea routes needed for an amphibious landing, a military expert said. The disruptions occurred on Tuesday and lasted about 10 hours as China conducted live-fire drills in the Taiwan Strait. The Civil Aviation Administration (CAA) said the exercises affected 857 international flights and 84 domestic flights, affecting more than 100,000 travelers. Su Tzu-yun (蘇紫雲), a research fellow at the government-sponsored Institute for National Defense and Security Research, said the air
Taiwan lacks effective and cost-efficient armaments to intercept rockets, making the planned “T-Dome” interception system necessary, two experts said on Tuesday. The concerns were raised after China’s military fired two waves of rockets during live-fire drills around Taiwan on Tuesday, part of two-day exercises code-named “Justice Mission 2025.” The first wave involved 17 rockets launched at 9am from Pingtan in China’s Fujian Province, according to Lieutenant General Hsieh Jih-sheng (謝日升) of the Office of the Deputy Chief of the General Staff for Intelligence at the Ministry of National Defense. Those rockets landed 70 nautical miles (129.6km) northeast of Keelung without flying over Taiwan,
A strong continental cold air mass is to bring pollutants to Taiwan from tomorrow, the Ministry of Environment said today, as it issued an “orange” air quality alert for most of the country. All of Taiwan except for Hualien and Taitung counties is to be under an “orange” air quality alert tomorrow, indicating air quality that is unhealthy for sensitive groups. In China, areas from Shandong to Shanghai have been enveloped in haze since Saturday, the ministry said in a news release. Yesterday, hourly concentrations of PM2.5 in these areas ranged from 65 to 160 micrograms per cubic meter (mg/m³), and pollutants were
