people)an increased level (18-21 points), 27% (8 people) with a high level (22-25 points) and 10% (3 people) with a very high level (26-28 points). As shown by the results of the survey on a scale for assessing the impact of a traumatic event, 20% of respondents (6 people) were dominated by symptoms of avoidance, 27% (8 people) invasion, and 53% (16 people) symptoms of arousal. Conclusions: the combat experience of most patients who were in the zone of Operation of the incomporated forces are in the range from medium to high. Only 10% received a very high level influence of combat trauma. The length of time spent by respondents in the combat zone ranged from 60 to 340 days. Avoidance symptoms prevailed in 20% of respondents (6), intrusion symptoms prevailed in 27% (8), and arousal symptoms in 53% (16). Therefore, in the future, it is in this direction that the target of psychotherapeutic and psycho-educational programs in this category of patients will be considered.

Infectious mononucleosis (IM) is the most typical clinical manifestation of herpesvirus infections. Aim: to analyze the features of clinical and laboratory diagnostics of IM in children. Materials and methods. The history of the diseases of 60 patients (random sampling) hospitalized in the infectious department of the Regional Infectious Children's Clinical Hospital during 2018 has been studied. The age of children was 2 to 16 years old, boys were 34 (56.7%), girls-26 (43.3%). Diagnosed with IM with a typical course of mild degree in 4 (6.6%) patients with moderate severity-49 (81.7%), severe-7 (11.7%). Acute course occurred in 43 (71.7%) patients, protracted-11 (18.3%), relapse-6 (10%). The revealed complications: thrombocytopenic purpura in 1 patient-(1.7%), convulsive syndrome-2 (3.3%). Results. During the hospitalization the following complaints were found: increase of cervical lymph nodes-58 (96.6%) patients; pain in the throat during swallowing-51 (85%), difficulty in nasal breathing-49 (81.6%), febrile fever, for at least 3 days-53 (88.3%), exanthema in the skin-7 (11.6%); sluggishness, drowsiness, general weakness-60 (100%) patients.

In the clinical analysis of blood during the first or second week of the disease, the following changes were observed: leukocytosis <15*10 9-44 (73.3%), leukocytosis > 15*10 9-7 (11.6%), leukocyte formula displacement to the left-19 (31.6%), lymphomonocytosis was recorded in 41 patients (68.3%), atypical mononuclear to 10%-27 (45%), atypical mononuclear more than 10-20%-14 (23.3%), anemia-47 (78.3%).
