The CDC announced on October 8, 2026 that a new locally transmitted dengue fever case has been added, involving a woman in her 40s residing in Pingtung City, Pingtung County. In early October she developed fever, headache, muscle pain, and diarrhea. After seeking medical care and being reported for testing, she was confirmed to have dengue fever, with dengue virus type 4 detected. The patient is currently hospitalized, and cohabitants have no suspected symptoms.
The CDC stated that the case's incubation period activities were mainly near the residence in Pingtung County, with additional activity history in neighboring counties and cities, and no overseas travel history, indicating a locally transmitted case. The specimen will be further sequenced to clarify the possible source of infection. Health authorities have carried out emergency chemical control measures, vector mosquito density surveys, and environmental risk assessments around the patient's residence, and have intensified source elimination and public education. They also plan to expand testing, urging the public to implement mosquito prevention measures and cooperate with related control efforts. If fever, headache, retro‑orbital pain, muscle or joint pain, rash, or other suspected dengue symptoms appear, please seek medical care promptly and inform the physician of travel and activity history.
CDC surveillance data show that, to date in 2026, a total of 188 confirmed dengue cases have been reported nationwide, including 13 locally transmitted cases residing in Kaohsiung City (10), Changhua County (2) and Pingtung County (1). The remaining 175 cases are imported, with infection locations primarily in Southeast and South Asian countries such as Vietnam (48), Indonesia (29), and the Philippines (21). The number of cases is lower than the same period in 2025 (198).
The CDC reminds that recent temperatures remain suitable for mosquito activity and breeding. The public is urged to practice “inspect, overturn, clean, and scrub,” actively removing breeding sites inside and outside homes to reduce vector mosquito density. When outdoors, wear light‑colored long‑sleeved clothing and use government‑approved mosquito repellents containing effective ingredients such as DEET, Picaridin, or IR‑3535. If fever, headache, retro‑orbital pain, muscle or joint pain, rash, or other suspected dengue symptoms occur, seek medical care promptly and inform of travel history. Medical facilities should also stay vigilant, intensify questioning of patients about TOCC (travel, occupation, contact, and cluster history), and may use dengue NS1 rapid test kits to aid diagnosis and early reporting, enabling health authorities to implement control measures promptly.
