Colombian Ocular Infectious Epidemiology Study (COIES): Herpes Zoster Ophthalmicus prevalence and sociodemographic characterization, 2015-2019.

OBJECTIVES

This study aimed to estimate the prevalence of Herpes Zoster Ophthalmicus (HZO) and describe the sociodemographic disease distribution by age, sex, and region in Colombia using National Health Registry data between January 1, 2015, to December 31, 2019.

METHODS

We conducted a cross-sectional study using the Integrated Social Protection Information System database from the Colombian Ministry of Health, the unique official database in the country. We used the specific code of the International Classification of Diseases for HZO (B02.3) from 2015-2019 to estimate the prevalence and the demographic status of the disease in Colombia.

RESULTS

The average prevalence was 0.99 in 100,000 inhabitants. Females represented 54.44% of the cases from 2,378 included patients. The distribution by age has a continual increase from the quinquennial group of 55 years. The geographic analysis shows a higher disease burden in the Andean region, followed by the Caribbean and Pacific regions.

CONCLUSION

This is the first study that determines the HZO epidemiological characteristics based on a National Health database in our region. We found an age distribution similar to previous studies and suggest that higher altitudes correlate with a higher burden of the disease.
