Dengue mortality in Colombia, 1985-2012

Area of Science:

• Public Health
• Epidemiology
• Infectious Diseases

Background:

• Dengue poses a significant public health challenge in Colombia, incurring substantial economic and social costs, especially during outbreaks.
• Understanding dengue's mortality patterns is crucial for effective public health interventions.

Purpose of the Study:

• To analyze the trends and characteristics of dengue mortality in Colombia from 1985 to 2012.
• To identify demographic and geographic factors associated with dengue mortality.

Main Methods:

• A descriptive epidemiological study was conducted.
• Mortality data and population projections were obtained from the Departamento Administrativo Nacional de Estadística (DANE).
• Mortality rates, rate ratios, and case fatality rates were calculated for the period 1985-2012.

Main Results:

• A total of 1,990 dengue deaths were recorded in Colombia between 1985 and 2012.
• Dengue mortality rates exhibited a statistically significant increasing trend from 1985 to 1998.
• Higher mortality rates were observed in males under 5 years and over 65 years, and in municipalities categorized 1-4 from 1995-2012. Case fatality rates ranged from 0.01% to 0.39%.

Conclusions:

• Dengue mortality is preventable with the effective implementation and evaluation of the Integrated Management Strategy (EGI)-Dengue.
• Promoting an informed culture is recommended to support decision-making and resource allocation for dengue control.
• Reducing dengue deaths requires a concerted effort in public health policy and community engagement.
