EPIDEMIOLOGICAL ANALYSIS OF MEASLES OUTBREAK IN KYRGYZ REPUBLIC FOR THE 2018 YEAR

Abstract

Objective: To analyze the development of the measles outbreak in 2018 among the population of the Kyrgyz Republic to improve the prevention system in the country. Methods: An operational and retrospective epidemiological analysis of official statistics has been carried out. The diagnosis of measles was confirmed with the immunoenzyme analysis (IEA) using the Vector-Best IgM Measles n-905 test system. The genotype of the measles virus was determined in the laboratory of the Moscow Research Epidemiology and Microbiology Institute named after G.N. Gabrichevsky, the material served as nose-swallow scrape and urine. Results: A total of 1,005 cases of measles have been reported in the country (an intensive indicator of 16,10/0000), of which 515 have been laboratoryconfirmed and 490 cases have been clinically and epidemiologically interconnected. The areas of risk were Bishkek with an incidence rate of 57.2% and Chui region – 24.5%. Risk groups were children under the year of life – 45.7% and at the age of 1-4 years – 37.1 %. Risk time is spring-summer and autumn periods. The main proportion of patients were unvaccinated – 92%, of which 45% were children under the year, 21% – due to failures, 11% – with medical recusals and 5% – due to migration of the population. Conclusion: The presence of non-immune stratum among the population, formed by the causes of frequent failures, migration of the population and medical recusals, as well as in the conditions of the emergence of hospital-acquired hotbeds in the infectious and non-infectious hospitals have contributed to the outbreak of measles in Kyrgyzstan among the young children.
