Wearing masks and social distancing should still be recommended in four types of settings, as a COVID-19 wave caused by new Omicron subvariants of SARS-CoV-2 might occur in the middle of next month, National Taiwan University (NTU) College of Public Health professor Tony Chen (陳秀熙) said yesterday.
Chen made the comment after the Central Epidemic Command Center announced that people would from today no longer need to wear a mask outside.
He suggested that Taiwan implement a double-track method that focuses on select disease prevention measures, such as enhancing immune protection from infection and through vaccination, and self-disease prevention, while other restrictions should be lifted in phases.

As immunity from vaccination wanes — especially as early vaccines did not target the Omicron variant, which emerged after they were developed — people should get inoculated with newer bivalent vaccines, he said.
Chen said self-disease prevention guidelines seek to reduce reinfection and protect people who are vulnerable and might develop severe symptoms or die if they are infected.
People should wear a mask and practice social distancing on public transportation, at public gatherings, large events and in healthcare facilities, as the spread of a new subvariant might lead to a large outbreak, he said.
Masking, social distancing and other personal preventive measures are also recommended during holiday gatherings, especially if vulnerable family members are involved, he added.
Lifting most restrictions would allow society to return to normal, Chen said, adding that people should not worry too much, as the local community has built up immunity.
People should feel free to resume holiday celebrations, travel overseas and help the economy recover from the COVID-19 pandemic, Chen said.
However, he said new subvariants have been detected among local cases, and a new wave of infections might occur in the middle of next month, as year-end and New Year’s Eve events might contribute to a spike in cases.
However, the next wave is expected to have fewer cases than previous ones, he said.
Commenting on the COVID-19 situation in China, Chen said that a large outbreak might occur there.
Chinese have had little exposure to the virus, as Beijing has maintained a “zero COVID-19” policy throughout the pandemic and the domestically developed vaccines, which target earlier variants, offer increasingly less protection for those who received them soon after they became available, he said.
“If the zero COVID-19 strategy continues, [China] will certainly pay a significant cost,” he said.
The country might have more than 1 million cases per day by the end of this month, he said, adding that the number of severe cases and deaths from the disease would also increase.
The best way to prevent that would be administering bivalent vaccines, Chen said.
FAST TRACK? Chinese spouses must renounce their Chinese citizenship and pledge allegiance to Taiwan to gain citizenship, some demonstrators said Opponents and supporters of a bill that would allow Chinese spouses to obtain Taiwanese citizenship in four years instead of six staged protests near the Legislative Yuan in Taipei yesterday morning. Those who oppose the bill proposed by the Chinese Nationalist Party (KMT) demanded that Chinese spouses be granted citizenship only after renouncing their Chinese citizenship, passing a citizenship test and pledging allegiance to Taiwan. The demonstrators, who were protesting at a side entrance to the Legislative Yuan on Jinan Road, were mostly members of the Taiwan Association of University Professors and other organizations advocating Taiwanese independence. Supporters of the bill, led
SILENT MAJORITY: Only 1 percent of Chinese rejected all options but war to annex Taiwan, while one-third viewed war as unacceptable, a university study showed Many Chinese are more concerned with developments inside their country than with seeking unification with Taiwan, al-Jazeera reported on Friday. Although China claims Taiwan as its own territory and has vowed to annex it, by force if necessary, 23-year-old Chinese Shao Hongtian was quoted by al-Jazeera as saying that “hostilities are not the way to bring China and Taiwan together.” “I want unification to happen peacefully,” Shao said. Al-Jazeera said it changed Shao’s name to respect his wish for anonymity. If peaceful unification is not possible, Shao said he would prefer “things to remain as they are,” adding that many of his friends feel
Taiwan has “absolute air superiority” over China in its own airspace, Deputy Minister of National Defense Po Horng-huei (柏鴻輝) told a meeting of the legislature’s Foreign Affairs and National Defense Committee on Monday, amid concern over whether Taipei could defend itself against a military incursion by Beijing. Po made the remarks in response to a question from Democratic Progressive Party Legislator Chiu Chih-wei (邱志偉) on whether Taiwan would have partial or complete air superiority if Chinese People’s Liberation Army (PLA) warplanes were to enter Taiwan’s airspace. Po, a retired pilot, said that the Taiwanese military has “absolute air superiority” over PLA
A shipment of basil pesto imported by Costco Wholesale Taiwan from the US in the middle of last month was intercepted at the border after testing positive for excessive pesticide residue, the Food and Drug Administration (FDA) said yesterday. Samples taken from a shipment of the Kirkland Signature brand of basil pesto imported by Costco contained 0.1 milligrams per kilogram of ethylene oxide, exceeding the non-detectable limit. Ethylene oxide is a carcinogenic substance that can be used as a pesticide. The 674kg shipment of basil pesto would either be destroyed or returned to its country of origin, as is the procedure for all
