The number of local COVID-19 cases confirmed this week increased 23.1 percent from a week earlier, the Central Epidemic Command Center (CECC) said yesterday, as it reported 32,529 new local cases.
Centers for Disease Control (CDC) Director-General Chou Jih-haw (周志浩), head of the CECC’s disease surveillance division, said that 283 imported cases and 42 deaths were also confirmed yesterday.
The number of new local cases confirmed was about 20 percent more than on Saturday last week, showing a clear growth trend, Chou said.

Deputy Minister of Health and Welfare Victor Wang (王必勝), who heads the CECC, said more than 212,000 cases have been reported this week.
Weekly case numbers have been increasing for three consecutive weeks, showing that the Omicron BA.5 subvariant of SARS-CoV-2 has arrived and cases are surging as a result, he said.
The Food and Drug Administration on Friday issued an emergency use authorization (EUA) for Moderna’s second-generation bivalent COVID-19 vaccine for adults.
Commentators have asked why the government is purchasing the bivalent vaccine that targets the Omicron BA.1 subvariant and the original 2020 strain, rather than a trivalent vaccine that targets the BA.4 and BA.5 subvariants along with the original strain.
Wang said that data for the Omicron BA.1-adapted bivalent vaccine are more complete, and include animal testing and phase 2 and 3 clinical trials.
It has gained emergency use authorization in the UK, Switzerland, Australia, the EU, Canada and Taiwan between Aug. 15 and Friday, showing that it has international recognition, Wang said.
The Omicron BA.4 and BA.5-adapted vaccine was just approved by the US on Wednesday, and there is not enough clinical evidence to prove whether it is more effective than the BA.1-adapted vaccine, he said.
Moderna and Pfizer-BioNTech have not submitted the data to Taiwan for review, he said, adding that the companies have said they cannot deliver BA.5-adapted bivalent vaccines to countries other than the US at this time.
Data from clinical trials on the Omicron BA.1-adapted bivalent vaccine have shown a certain level of protection against different strains of Omicron, so as new cases are increasing, that vaccine is considered effective enough to be purchased, Wang said.
The center is also reserving capacity to purchase new vaccines, possibly including the BA.4 and BA.5-adapted vaccine, he added.
“When it is already raining, or when heavy rain is about to fall, we should use the umbrella we have at hand to block the rain, instead of getting wet and hoping to buy a new type of umbrella,” he said.
The center would not force anyone to get vaccinated, so if some people insist on waiting for a newer vaccine, they can do so, but they should not try to stop others from getting vaccinated with what is available, he said.
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
