A Long-term Retrospective Epidemiological Analysis of the Incidence of Rotavirus Infection in the Altai Krai for 2001–2023

Relevance. The urgency of the problem of rotavirus infection, primarily among children, is due to the steady preservation of leading places in the structure of childhood morbidity. Despite the existing preventive measures, the incidence of rotavirus infection has been steadily increasing over the past 10 years. Vaccination coverage in our country in recent years has not exceeded 10-12% of the target cohort, which in general cannot have a significant impact on the incidence of rotavirus infection and requires special attention. Aim. To assess the epidemiologic situation on the incidence of rotavirus infection in Altai Krai in 2001–2023. Materials and methods. A retrospective epidemiological analysis of the incidence of rotavirus infection in the Altai Krai was carried out using data from statistical reporting forms No. 2 of the Federal State Statistical Observation «Information on infectious and parasitic diseases» in the Altai Krai in 2001–2023. Results. A long-term retrospective epidemiological analysis of rotavirus infection incidence was carried out. It was noted: an increase in the share of rotavirus infection in the structure of acute intestinal infections; a tendency for an increase in morbidity rates in the Altai Krai; the average long-term morbidity rate among children 0–17 years old exceeded that among adults by 67 times; in the structure of cases, the main proportion was children 1–2 years old; the greatest contribution to the formation of morbidity was made by unorganized children (75%) vaccination had no effect on morbidity, since vaccine coverage of Altay Krai population does not exceed 0.1%. Conclusion. The reasons for close monitoring of rotavirus infection and improvement of preventive measures, including vaccine prophylaxis, are substantiated
