Mpox Cases in Serbia, 2022.

BACKGROUND

On 23 July 2022, the World Health Organization (WHO) declared the mpox multi-country outbreak as a Public Health Emergency of International Concern. This study aimed to identify the epidemiological and clinical characteristics of confirmed mpox cases reported in Serbia in 2022.

METHODS

The mpox WHO case definition was used. Incidence rates (IRs) and incidence rate ratios (IRRs) by age groups and nomenclature of territorial units for statistics level 3 (NUTS-3) with 95% confidence intervals (CIs) were calculated.

RESULTS

Between June and October 2022, 43 laboratory-confirmed cases were reported. All were unvaccinated males, with the mean age of 34 (±7.4) years. Out of the total, 72.1% cases were men who have sex with men (MSM), who reported sexual intercourse either with multiple or unknown partners (p < 0.01). Fifteen cases (34.9%) lived with HIV, mostly in the 30-39 age group (p = 0.023). People living in Belgrade City NUTS-3 were six times more likely to become infected compared to South Backa citizens (IRR: 6.03, 95% CI: 1.47-25.53).

CONCLUSIONS

In Serbia, mpox mainly affected MSM aged 30-39 and living in urban areas. Health promotion and vaccine implementation should be prioritized in populations with a higher risk.
