Weekly hospital visits for flu-like illnesses last week were the highest for the period in 10 flu seasons, while the first case of infant botulism in Taiwan in four years was reported, the Centers for Disease Control (CDC) said yesterday.
CDC Epidemic Intelligence Center Deputy Director Lee Chia-lin (李佳琳) said there were 141,777 hospital visits for flu-like illnesses between Jan. 12 and Saturday, the highest for the week in 10 flu seasons.
The weekly number is projected to continue increasing, Lee added.

Sixty-four cases of severe flu were reported last week, with 90 percent having influenza A(H1N1), she said, adding that 86 percent of the people with severe flu were unvaccinated this flu season.
Six flu deaths were reported last week, she said.
Flu activity in Japan, South Korea, China and Hong Kong is high; while it is high and rising slightly in Europe; increasing in Canada; and reducing, but still above the epidemic threshold in the US, Lee said.
CDC physician Lin Yung-ching (林詠青) said the youngest of the people who died with the flu last week was a man in his 30s who was immunocompromised and unvaccinated.
The man was hospitalized for pneumonia and died of septic shock three weeks later, Lin said.
The youngest person with severe flu last week was a baby aged between six months and one year who had cold-like symptoms, he said,
The girl was hospitalized with low blood oxygen and pneumonia, and was being treated in an intensive care unit after spending more than 10 days in hospital, he said.
Meanwhile, a child under the age of one was diagnosed with botulism, the first case in the country in four years, Lee said.
The baby, who lives in northern Taiwan, does not have a congenital disease, but developed symptoms including constipation, loss of appetite and decreased vitality from Dec. 22, Lin said.
She was taken to a hospital for treatment on Jan. 4, Lin said.
The medical team initially suspected an intestinal obstruction or a congenital intestinal disorder, but examinations showed a deep tendon reflex disorder, droopy eyelids and limb weakness, while neuroimaging scans showed no brain abnormalities, he said.
Further tests detected Clostridium botulinum in her feces and she was diagnosed with infant botulism, Lin said, adding that she has been treated with an antitoxin and her symptoms have eased after being hospitalized for more than two weeks, although she is still in an intensive care unit.
The girl’s family said her diet is mainly breastmilk with some canned foods, such as fruit sauces and pureed vegetables, Lin said, adding that the local health department has collected samples of the canned food for testing.
C botulinum is widespread, usually found as spores, Lin said.
Honey is a typical culprit in contamination cases, he said, adding that the bacteria can produce a neurotoxin that causes botulism, with symptoms including blurred or double vision, drooping eyelids, difficulty speaking and swallowing, and muscle weakness.
It can be fatal if not treated promptly, he said.
The intestinal tracts of infants lack some protective bacteria and they have weaker immunity, so if they ingest the spores, the bacteria can colonize the intestine and produce a toxin, leading to botulism, he said.
Adults should avoid feeding honey to children younger than one, while fruits and vegetables should be thoroughly washed and their skins removed to negate possible contamination from soil, he said.
People should avoid eating canned food or food from jars when the lid has swollen, he added.
A magnitude 4.9 earthquake struck off Tainan at 11:47am today, the Central Weather Administration (CWA) said. The hypocenter was 32.3km northeast of Tainan City Hall at a depth of 7.3km, CWA data showed. The intensity of the quake, which gauges the actual effect of a seismic event, measured 4 in Tainan and Chiayi County on Taiwan's seven-tier intensity scale, the data showed. The quake had an intensity of 3 in Chiayi City and County, and Yunlin County, while it was measured as 2 in Kaohsiung, Nantou County, Changhua County, Taitung County and offshore Penghu County, the data showed. There were no immediate reports of
Weather conditions across Taiwan are expected to remain stable today, but cloudy to rainy skies are expected from tomorrow onward due to increasing moisture in the atmosphere, according to the Central Weather Administration (CWA). Daytime highs today are expected to hit 25-27°C in western Taiwan and 22-24°C in the eastern counties of Yilan, Hualien, and Taitung, data on the CWA website indicated. After sunset, temperatures could drop to 16-17°C in most parts of Taiwan. For tomorrow, precipitation is likely in northern Taiwan as a cloud system moves in from China. Daytime temperatures are expected to hover around 25°C, the CWA said. Starting Monday, areas
A Taiwanese software developer has created a generative artificial intelligence (AI) model to help people use AI without exposing sensitive data, project head Huang Chung-hsiao (黃崇校) said yesterday. Huang, a 55-year-old coder leading a US-based team, said that concerns over data privacy and security in popular generative AIs such as ChatGPT and DeepSeek motivated him to develop a personal AI assistant named “Mei.” One of the biggest security flaws with cloud-based algorithms is that users are required to hand over personal information to access the service, giving developers the opportunity to mine user data, he said. For this reason, many government agencies and
Taiwan has recorded its first fatal case of Coxsackie B5 enterovirus in 10 years after a one-year-old boy from southern Taiwan died from complications early last month, the Centers for Disease Control (CDC) said yesterday. CDC spokesman Lo Yi-chun (羅一鈞) told a news conference that the child initially developed a fever and respiratory symptoms before experiencing seizures and loss of consciousness. The boy was diagnosed with acute encephalitis and admitted to intensive care, but his condition deteriorated rapidly, and he passed away on the sixth day of illness, Lo said. This also marks Taiwan’s third enterovirus-related death this year and the first severe
