Eligibility for government-funded influenza antiviral drugs would be expanded from Jan. 20 to Feb. 28 to include seven groups considered to be at higher risk of spreading the virus, as the flu is predicted to enter an epidemic period at the end of the month, the Centers for Disease Control (CDC) said yesterday.
CDC communicable disease monitoring data released on Tuesday showed that the number of hospital visits for flu-like illnesses for the final week of last year was 82,161, which is about the same as the previous week.
CDC Deputy Director-General and spokesman Lin Min-cheng (林明誠) said the centers expect the flu might enter another epidemic period at the end of this month and reach a peak near the Lunar New Year holiday in the middle of next month.

The CDC said while it typically broadens eligibility during the epidemic period, the expansion from Jan. 20 is a preemptive preparation.
The seven eligible groups are: epidemic prevention personnel in medical institutions (including registered medical practitioners and non-medical staff in healthcare facilities); caregivers and staff in nursing homes, long-term care facilities and similar institutions; childcare personnel in kindergartens, staff in childcare centers and at-home childcare providers (nannies); students in kindergarten, elementary school, junior-high school, senior-high school, vocational high school or the first three years of a five-year junior college; people living with or caring for an someone at high risk of severe influenza complications; poultry and livestock farming personnel, zoo staff and animal epidemic prevention personnel; as well as people who live in high-density facilities that are prone to cluster infections.
Lin said data over the past four weeks showed that influenza remains the most prevalent respiratory virus in Taiwan, accounting for 43.8 percent of cases, significantly higher than adenoviruses at 15.8 percent and rhinovirus at 15.4 percent.
In related news, there have been reports of a rise in rhinovirus cases in China.
Rhinovirus infections in Taiwan increased slightly recently, but rhinovirus and adenoviruses are still the second and third-most common viruses respectively in the nation, and have not exceeded the number of flu viruses, he said.
As more people are expected to travel near the Lunar New Year, viruses from abroad could enter the country, Lin said, adding that the CDC would continue to monitor viral activity changes in flu virus strains, as well as adenoviruses, the rhinovirus, the respiratory syncytial virus and other respiratory pathogens.
The rhinovirus tends to infect the upper respiratory tract and rarely extends to the lower respiratory tract, Lin said.
Typical symptoms include a runny nose and coughing, which are usually resolved in seven to 10 days, he said, adding that the fatality rate is near zero, so the health risk is not as significant as flu viruses.
“It usually only causes inconvenience to people’s daily lives, but does not cause incapacity to work,” Lin said.
In comparison, a flu infection often causes whole-body soreness and fatigue, he said, adding that the risk of severe complications is higher in elderly people and those with chronic diseases.
MacKay Memorial Hospital pediatrics director Chi Hsin (紀鑫) said common symptoms of a rhinovirus infection include coughing, a runny nose and a fever.
They could be classified into three types — A, B and C — of infections, he added.
For example, a rhinovirus C infection could trigger asthma exacerbation or an allergic reaction, and could extend to the lower respiratory tract, so it poses higher risk to children with asthma or chronic liver disease, he said.
A relapsing fever, loss of appetite or shortness of breath — especially if infants younger than one year old breathe more than 50 times a minute — in an infected child might be a sign of bacterial coinfection, Chi said.
If that is the case, the child should be taken to see a doctor as soon as possible, he added.
Linkou Chang Gung Memorial Hospital deputy superintendent Chiu Cheng-hsun (邱政洵) said people who are immunocompromised, or have underlying conditions or coinfection from other viruses might be at higher risk if they contract rhinovirus.
As for whether the rising number of people with rhinovirus in China is abnormal, Chiu said more observation is needed to see if there are virus mutations or increased coinfections.
MAKING WAVES: China’s maritime militia could become a nontraditional threat in war, clogging up shipping lanes to prevent US or Japanese intervention, a report said About 1,900 Chinese ships flying flags of convenience and fishing vessels that participated in China’s military exercises around Taiwan last month and in January have been listed for monitoring, Coast Guard Administration (CGA) Deputy Director-General Hsieh Ching-chin (謝慶欽) said yesterday. Following amendments to the Commercial Port Act (商港法) and the Law of Ships (船舶法) last month, the CGA can designate possible berthing areas or deny ports of call for vessels suspected of loitering around areas where undersea cables can be accessed, Oceans Affairs Council Minister Kuan Bi-ling (管碧玲) said. The list of suspected ships, originally 300, had risen to about 1,900 as
DAREDEVIL: Honnold said it had always been a dream of his to climb Taipei 101, while a Netflix producer said the skyscraper was ‘a real icon of this country’ US climber Alex Honnold yesterday took on Taiwan’s tallest building, becoming the first person to scale Taipei 101 without a rope, harness or safety net. Hundreds of spectators gathered at the base of the 101-story skyscraper to watch Honnold, 40, embark on his daredevil feat, which was also broadcast live on Netflix. Dressed in a red T-shirt and yellow custom-made climbing shoes, Honnold swiftly moved up the southeast face of the glass and steel building. At one point, he stepped onto a platform midway up to wave down at fans and onlookers who were taking photos. People watching from inside
Japan’s strategic alliance with the US would collapse if Tokyo were to turn away from a conflict in Taiwan, Japanese Prime Minister Sanae Takaichi said yesterday, but distanced herself from previous comments that suggested a possible military response in such an event. Takaichi expressed her latest views on a nationally broadcast TV program late on Monday, where an opposition party leader criticized her for igniting tensions with China with the earlier remarks. Ties between Japan and China have sunk to the worst level in years after Takaichi said in November that a hypothetical Chinese attack on Taiwan could bring about a Japanese
The WHO ignored early COVID-19 warnings from Taiwan, US Deputy Secretary of Health and Human Services Jim O’Neill said on Friday, as part of justification for Washington withdrawing from the global health body. US Secretary of State Marco Rubio on Thursday said that the US was pulling out of the UN agency, as it failed to fulfill its responsibilities during the COVID-19 pandemic. The WHO “ignored early COVID warnings from Taiwan in 2019 by pretending Taiwan did not exist, O’Neill wrote on X on Friday, Taiwan time. “It ignored rigorous science and promoted lockdowns.” The US will “continue international coordination on infectious
