Abstract
Objective: to analyze the epidemiological situation of acute intestinal infections of norovirus etiology in Armenia for 2016–2024.
Materials and methods: The analysis is based on the data of an epidemiological study of 1154 cases of norovirus infection, emergency notifications about which were received by the National Center for Disease Control and Prevention of the Ministry of Health of Armenia. Descriptive epidemiological methods were used. Statistical and correlation analysis of a number of data was also conducted.
Results: Noroviruses have caused 3,1–22,7% of all acute intestinal infections of viral etiology. During the analyzed period, an increase in the incidence of norovirus infection among the population of Armenia is recorded. A predominance of younger age groups in the structure of cases was revealed. In all cases, the diagnosis was established based on the PCR results. An analysis of the distribution of cases by region revealed a concentration of cases in the capital and nearby regions, which may be due to the insufficient capacity for laboratory diagnostics of acute intestinal infections of viral etiology in remote regions.
Conclusion: Our study showed an increasing burden of acute intestinal infections of norovirus etiology in Armenia. The incidence rate in younger age groups is several times higher than among adults. In the absence of vaccination against this disease, the healthcare system should actively educate the population about methods of preventing acute intestinal infections, including norovirus.
