  The second instance of vertical transmission of dengue fever this year was reported and the death of the youngest person due to flu this season was confirmed last week, the Centers for Disease Control (CDC) said yesterday, adding that 1,521 local dengue cases and 90,386 hospital visits for flu-like illness were reported last week.

  There were 1,521 local dengue cases last week, with Tainan having 1,283, Kaohsiung 119, and 14 other administrative regions reporting one to 32, CDC Epidemic Intelligence Center Director Guo Hung-wei (郭宏偉) said.

  The number of weekly new cases has dropped slightly, but the risk of infection is still high, Guo said.

  Cases so far this year are the second-highest for the period in a decade, he said, adding that nine severe dengue cases and seven deaths were confirmed last week.

  CDC physician Lin Yung-ching (林詠青) said that a case of mother-to-infant transmission of dengue was confirmed last week, affecting a five-day-old boy, the second such case this year and the third ever in Taiwan.

  The mother was diagnosed with dengue one day after giving birth on Wednesday last week, and the child developed a fever five days later and tested positive for dengue, Lin said.

  As the baby had been in hospital since he was born and had a short incubation period, the disease was most likely transmitted vertically, he said.

  Meanwhile, 90,386 hospital visits for flu-like illness were reported last week, slightly fewer than the previous week, potentially affected by fewer people seeking medical attention over the long weekend, Guo said.

  The most common viruses identified from respiratory illnesses in the past four weeks were flu viruses, predominantly influenza A strains H1N1 and H3N2, he said, adding that 40 severe cases and eight flu-related deaths were confirmed last week.

  One of the people who died was an 11-month-old boy, the youngest flu death this flu season, Lin said, adding that the child had congenital heart disease and had a fever for five days, followed by rashes — diagnosed as roseola infantum — after the fever abated.

  However, he developed a fever again for two to three days, and was rushed to hospital with decreased vitality and loss of appetite, Lin said.

  He had a high fever, shortness of breath, cyanosis and low blood pressure, and tested positive for flu, and was admitted to an intensive care unit, Lin said.

  Test results showed that the boy also had myocarditis and pneumonia, he said.

  He died the day he was hospitalized, Lin added.

  The CDC suggests that children get vaccinated when they are older than six months, especially if they have underlying health conditions, as they are at higher risk of developing severe complications, Lin added.

  There were 10,920 hospital visits for enterovirus infection last week, about 14.8 percent fewer that the previous week, CDC Deputy Director-General Tseng Shu-hui (曾淑慧) said.

  Although the number might have been affected by the long weekend, it was still above the epidemic threshold, so people with young children should remain vigilant for early signs of severe complications, she said.
