Hyperendemic regions including Oceania, East Asia and Southeast Asia still had an increasing age-standardized incidence rate (ASR) of dengue infection in the last decade.

Both middle and high-middle SDI regions also had an increasing dengue infection ASR in the last decade.

There were higher dengue incidence rates among the elderly than in other age groups in low and low-middle SDI regions.

There have been increasing numbers of dengue episodes among the elderly in most GBD regions.

More attention should be paid to developing targeted prevention strategies for dengue infection in crucial regions and older populations.
