Abstract：

The number of dengue cases in 2015 had been the highest compared with the numbers in past years since dengue fever became notifiable in Taiwan. During May–September 2015, 13,682 local cases, including 46 deaths, were reported. Of 46 deaths, 36 were directly related to dengue as determined by an expert committee.

The median age of the 46 deaths was 77 years (range49–94 years); 24 (52.2%) were male and 41 (89.1%) had at least one chronic conditions. Sixteen (34.8%) of 46 patients had initial presentations compatible to severe dengue fever. Of 30 cases that did not meet the criteria for severe dengue fever, 13 showed warning signs. Half of the mortality occurred within 5days after symptoms onset. It is important to monitor carefully for severe dengue and dengue with warning signs, especially in elderly patients and those who have multiple comorbidities, which implicate higher risk of mortality.
