Abstract


Background. The latest 1.5–2 decades were marked by the intensification of enterovirus infection (EI) in all regions of the world. There were sporadic cases and outbreaks with the involvement of several hundreds or thousands of people, and even powerful epidemics. The aim of the investigation was to study the clinical features of EI in season 2016 in children of Ternopil region. Materials and methods. The course of clinically diagnosed EI in 149 children was analyzed. Results. The peculiarities of EI course in season 2016 in Ternopil region were established. Most of EI cases (66.44 %) were registered in autumn. Infection has predominantly mild course, therefore only 36.91 % of the observed persons were hospitalized. The average age of ill children was 3.49 ± 0.78 years, with a slight predominance of boys (56.38 %). The onset of the disease was accompanied by intoxication symptoms in all the patients. 67.79 % patients had a short-term (1.87 ± 0.92 days) increase of body temperature ranged 37.6–40.0 °C; herpangina in 65.10 %; respiratory syndrome in 46.31 %; intestinal syndrome in 38.26 %; rash and hand-foot-and-mouth-disease in 32.21 %; epidermis desquamation on palms and soles in 12.75 %; onichomadesis in 22.82 %. Conclusions. EI in season 2016 in Ternopil region was characterized by considerable polymorphism of clinical symptoms with general intoxication syndrome in all patients observed. The low level (5.34 %) of laboratory verification at the diversity of enteroviruses and the diversity of clinical manifestations of the diseases they cause do not allow receive full clinical experience (although today it is possible to determine the enterovirus serotype by sequestration and phylogenetic analysis), determine the source of infection, determine the links between the probable source of infection and patients, and identify where the virus was transferred from and follow the changes of the clinical course.
