The CDC has published a new report on Hawaii Island’s dengue fever outbreak. It is co-authored by Dr. Sarah Park, the Hawaii State Epidemiologist and details the initial stages of the outbreak.
Here is the demographic breakdown for the first 107 cases. Of interest is that the median age was 29 years old, and that the number of infected travelers has remained relatively low throughout the course of the outbreak to today:
“Among the 107 dengue patients identified, 15 (14%) were hospitalized; no deaths were reported. Ninety-three (87%) cases occurred in Hawaii Island residents, and 14 in travelers visiting Hawaii Island; 62 (58%) patients were female, and the median age was 29 years (range = 0–80 years). Exposure information from a majority of patients suggested at least one area of concern south of Kona, Hawaii. However, further investigations are ongoing, and cases have been reported in persons who traveled to and potentially sustained or recalled actual mosquito bites in other parts of the island. Among these cases are at least 12 (12%) persons who were never in any area south of Kona during the period of likely infection (3–10 days before symptom onset).”
