A new coronavirus infection (COVID-19, Corona Virus Disease 2019) is a disease caused by the SARS-CoV-2 virus, presenting as both a mild acute respiratory viral infection and a severe form, with damage to various organs and systems. In children under 16 years of age infected with SARS-CoV-2, the vast majority of cases were mild, without marked neurological manifestations.This paper describes a case of acute disseminated encephalomyelitis in a five-year-old child associated with SARS-CoV-2, which caused difficulties in the differential diagnosis with demyelinating diseases and hereditary pathology. The disease was diagnosed in a family where both parentswere diagnosedwith COVID-19 by polymerase chain reaction (PCR).The CNSlesionwasrepresented by severe central hemiparesis, involvement of some cranial nerves, with impaired pelvic organ function. During the treatment there was a positive dynamicsin the somatic and neurologicalstatus. The patient was discharged for outpatient treatment with satisfactory rehabilitation potential.SARS-CoV-2 lesions of the nervous system in children can lead to life-threatening and fatal conditions. Timely diagnosis and a comprehensive approach to the management of a child with encephalomyelitis made it possible to avoid adverse effects of the disease and improve the rehabilitation prognosis.

The use of drugs with antioxidant and antihypoxant activity in combination with immunocorrectors for chronic occupational mercury intoxication in a contingent of disabled people aged 18 years and older makes it possible to increase the effectiveness of medical rehabilitation of this contingent. The developed treatment regimens affect the main links of pathogenetic tissue damage by mercury vapor. In order to increase the objectivity of the results of the study, the predominant neurological disorders occurring in the lower extremities must be diagnosed on a complex computer-dynamic complex "ZEBRIS" with the function of a diagnostic track with a power platform, which allows to identify the degree of distribution of force and pressure of the feet when walking, violations of static support capacity on a moving platform. We have analyzed statistical data on disability due to exposure to chronic mercury intoxication for the period 2019- 2021 in the Republic of Mordovia. Risk groups have been identified according to the degree of loss of professional ability to work, depending on age, duration of work in mercury production, concomitant diseases. Contingents of disabled people with impaired mental and statodynamic functions were identified. Groups of disabled people in need of medical and social rehabilitation measures have been identified.
