Health experts yesterday called attention to ventilation, sanitation and COVID-19 vaccination for families with members who are quarantining at home, after the government on Friday announced that cases of the virus with no or mild symptoms would no longer have to quarantine in a dedicated facility.
Huang Chien-hsien (黃建賢), chief epidemiologist at Shinkong Wu Ho-su Memorial Hospital in Taipei, said that the dominant Omicron variant of SARS-CoV-2 is less severe than previous variants.
Huang said he supports the new policy, as tracking large numbers of asymptomatic cases is not cost-effective.

However, the policy requires people to be mindful not to put themselves in environments where they are at greater risk of being exposed to the virus, he said.
People interacting with family members quarantining at home should pay attention to ventilation and continually sanitize spaces where the infected person has been, he said, suggesting to use bleach or alcohol for cleaning.
COVID-19 is transforming into a flu or cold-like disease, and the pandemic could take six or seven months to run its course, China Medical University Hospital deputy superintendent Hwang Kao-pin (黃高彬) said.
“This should be viewed as a good development, so long as exponential growth in hospitalizations does not occur,” he said.
The Central Epidemic Command Center (CECC) has requested local health authorities to set up door-to-door vaccination campaigns to raise the vaccination rate among older residents, Hwang said.
Such campaigns could help prevent outbreaks similar to the one that killed many nursing home residents in Hong Kong, he added.
A Swedish study showed that unvaccinated people have a 60 percent chance of being infected by a home-quarantined person who has a high viral load, even if the person stays in a separate room and masking and social distancing rules are followed, said Chiu Cheng-hsun (邱政洵), deputy superintendent of Chang Gung Memorial Hospital in New Taipei City’s Linkou District (林口).
This means that the new policy poses risks of community spread, Chiu said.
The CECC now allows domestic cases who are younger than 65 and have mild or no symptoms to quarantine at home, except pregnant women and those regularly undergoing dialysis.
Home-quarantined cases must stay in a separate room from uninfected household members, and shared bathrooms and showers must be properly disinfected after each use, the guidelines released on Friday say.
Home quarantines are only allowed for households with fewer than four uninfected members.
Upon ending home quarantine, the infected person and anyone living with them must practice self-health management for seven days, with mandatory self-administered rapid tests on the third day and seventh day.
People can leave home quarantine if they test negative in a home test or a polymerase chain reaction test.
Cases who still test positive 10 or more days after their initial diagnosis may also leave home quarantine if their cycle threshold value is 30 or higher, they have not had a fever for 24 hours and their other symptoms are easing.
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 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
Trips for more than 100,000 international and domestic air travelers could be disrupted as China launches a military exercise around Taiwan today, Taiwan’s Civil Aviation Administration (CAA) said yesterday. The exercise could affect nearly 900 flights scheduled to enter the Taipei Flight Information Region (FIR) during the exercise window, it added. A notice issued by the Chinese Civil Aviation Administration showed there would be seven temporary zones around the Taiwan Strait which would be used for live-fire exercises, lasting from 8am to 6pm today. All aircraft are prohibited from entering during exercise, it says. Taipei FIR has 14 international air routes and
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,
