High morbidity, mortality and development of complications make the problem of knowing features of the measles clinical course, timely diagnosis and active prevention highly relevant. The purpose of the research is to study the dynamics of the incidence and clinical features of measles in children during the outbreak of 2018–2019 in the city of Mariupol, Donetsk region. A peculiarity of the measles outbreak in 2018–2019 in Mariupol is prevalence of the disease in preschool children (60.4%), inclu­ding 30.2% – those under one year of age; low vaccination rate: 52.3% of children unvaccinated; only 22.2% of children were vaccinated twice, according to the schedule. In all age groups, a moderately severe measles course prevailed (69.8%). The clinical course of measles in preschool and school age children had definitive features. Thus, Belsky–Filatov–Koplik spots were observed three times more frequently in preschool children than in schoolchildren (63.9% and 23.3%, respectively). Abdominal pain and diarrhea were only observed in children under 6 years of age (30.2%). Skin pigmentation was absent in children under one year of age and was detected in preschool and school-age children (69.8%). Skin sloughing was only observed in schoolchildren (10.4%). Severe disease course occurred in patients of all ages (29.3%), but children aged under one year and preschool children with severe disease were two times more numerous than those of the school age. Among the observed complications, the vast majority were associated with the respiratory organs: pneumonia (38.3%), subcutaneous emphysema (1.7%), bronchitis (53.2%), laryngitis (3.3%), otitis media (5%). No fatalities were observed. The city should form a commitment to immunization, restore public trust in vaccination, using all forms and means of information, and develop a program to implement the vaccination schedule into practice.
