Weekly hospital visits for COVID-19 surged by 88 percent last week, the Centers for Disease Control (CDC) said yesterday, adding that the NB.1.8.1 subvariant of the SARS-CoV-2 virus has become the dominant strain spreading domestically.
Hospitals reported 19,097 visits for COVID-19, as weekly cases have increased for five consecutive weeks, CDC Epidemic Intelligence Center Director Guo Hung-wei (郭宏偉) said.
Of the 93 severe COVID-19 cases confirmed last week, 88.2 percent were not vaccinated with the JN.1-adapted COVID-19 vaccine, he said, adding that four people died.

Among the 330 severe COVID-19 cases reported this year, as of Monday, 74.2 percent were people aged 65 or older, 84 percent had underlying health conditions and 90 percent did not get the JN.1-adapted vaccine, Gou said.
Virus surveillance data from the past four weeks showed that the NB.1.8.1 subvariant has become the dominant strain locally, followed by the XEC and LP.8.1 subvariants, he said.
Aside from the Americas, global test positivity rates for the SARS-CoV-2 virus have been increasing, with the LP.8.1 subvariant being reported as the dominant strain globally, he said.
The youngest severe case last week was a 10-month-old girl who did not have underlying health issues, but was also not vaccinated, CDC physician Lin Yung-ching (林詠青) said.
She first had cold-like symptoms, then developed a loss of appetite, shortness of breath and croup, Lin said.
The girl has been hospitalized in an intensive care unit for four days and is still undergoing treatment, he added.
Local COVID-19 infections are rapidly increasing, with weekly hospital visits and severe cases reaching the highest this year, CDC Deputy Director-General Philip Lo (羅一鈞) said.
“We estimate that the peak will be in mid or late June,” he said. “Estimated hospital visits during the peak period are projected to be between 55,000 and 56,000 per week.”
The estimated peak weekly visits are only about half the number of the peak period during the previous wave of infections in summer last year, but people should still not let their guard down, Lo said.
The Ministry of Health and Welfare and the CDC have also made preparations in response to the growing infections, including making sure there are enough vaccines, medication and test kits, he said.
More than 17,000 people got vaccinated against COVID-19 last week, the highest weekly number in three months, and several local health departments have reported increased vaccine demand, he said.
Although 31,000 doses have been distributed this week, the CDC plans to distribute more on Friday, he said, adding that about 3.1 million doses are available.
The CDC also secured medications, including Remdesivir, Paxlovid and Molnupiravir, for the estimated usage of between five months to a year, while it also has open-ended contracts to import more if needed, Lo said.
The Food and Drug Administration last week asked domestic manufacturers to increase production of rapid test kits for at-home and hospital use, and it also contacted the nation’s four major convenience store chains and pharmacy chains to make test kits more accessible for purchase, he said.
Taiwanese scientists have engineered plants that can capture about 50 percent more carbon dioxide and produce more than twice as many seeds as unmodified plants, a breakthrough they hope could one day help mitigate global warming and grow more food staples such as rice. If applied to major food crops, the new system could cut carbon emissions and raise yields “without additional equipment or labor costs,” Academia Sinica researcher and lead author the study Lu Kuan-jen (呂冠箴) said. Academia Sinica president James Liao (廖俊智) said that as humans emit 9.6 billion tonnes of carbon dioxide compared with the 220 billion tonnes absorbed
The Taipei Mass Rapid Transit (MRT) Wanda-Zhonghe Line is 81.7 percent complete, with public opening targeted for the end of 2027, New Taipei City Mayor Hou You-yi (侯友宜) said today. Surrounding roads are to be open to the public by the end of next year, Hou said during an inspection of construction progress. The 9.5km line, featuring nine underground stations and one depot, is expected to connect Chiang Kai-shek Memorial Hall Station to Chukuang Station in New Taipei City’s Jhonghe District (中和). All 18 tunnels for the line are complete, while the main structures of the stations and depot are mostly finished, he
Taipei is to implement widespread road closures around Taipei 101 on Friday to make way for large crowds during the Double Ten National Day celebration, the Taipei Department of Transportation said. A four-minute fireworks display is to be launched from the skyscraper, along with a performance by 500 drones flying in formation above the nearby Nanshan A21 site, starting at 10pm. Vehicle restrictions would occur in phases, they said. From 5pm to 9pm, inner lanes of Songshou Road between Taipei City Hall and Taipei 101 are to be closed, with only the outer lanes remaining open. Between 9pm and 9:40pm, the section is
China’s plan to deploy a new hypersonic ballistic missile at a Chinese People’s Liberation Army Rocket Force (PLARF) base near Taiwan likely targets US airbases and ships in the western Pacific, but it would also present new threats to Taiwan, defense experts said. The New York Times — citing a US Department of Defense report from last year on China’s military power — on Monday reported in an article titled “The missiles threatening Taiwan” that China has stockpiled 3,500 missiles, 1.5 times more than four years earlier. Although it is unclear how many of those missiles were targeting Taiwan, the newspaper reported
