Zika virus (ZIKV) is an arthropod-borne virus (arbovirus) in the genus Flavivirus and the Flaviviridae family. In 1947 and 1948 ZIKV was first isolated from a nonhuman primate as well as from mosquitoes in Africa, respectively. For half a century, ZIKV infections in human were sporadic prior to 2015–2016 pandemic spreading. Transmission of ZIKV from mother to fetus can occur in any trimester of pregnancy, even if mother was an asymptomatic carrier. The clinical signs of ZIKV infection are nonspecific and can be misdiagnosed as some other infectious diseases, especially those caused by arboviruses such as Dengue and Chikungunya. ZIKV infection was solely associated with mild illness prior to the large French Polynesian and Brazil outbreaks, when severe neurological complications, Guillain–Barre syndrome and dramatically increased rate of severe congenital malformations (including microcephaly) were reported. The adaptation of ZIKV to an urban cycle in endemic areas suggests that the incidence of ZIKV infections may be underestimated. The pandemic of novel coronavirus infection (COVID-19) demonstrates that lessons from ZIKV pandemic propagation has not been learned properly.

Along with the respiratory, cardiovascular, gastrointestinal, rheumatological, and neurological manifestations of the new coronavirus infection (COVID-19), the effects of this virus on the ENT organs is undeniable, as the main portal of entry of any respiratory infection. It has been proven that symptoms such as hypo- and anosmia are associated with one of the ways of the virus penetration – transnasal, through the olfactory nerves into the central nervous system. Otorhinolaryngological complaints of patients are not limited only to deterioration or loss of smell, many note the appearance of dizziness, tinnitus, worsening of the course of chronic sensorineural hearing loss, and in some cases – sudden hearing loss, which may indicate damage to the auditory and vestibular analyzer by a viral agent. The mechanisms of development of the corresponding complications at the moment are still unclear. The presented article is a review of the literature data of foreign and domestic sources, which examines the central and peripheral neurological complications, the pathways and molecular features of the penetration of the virus, as well as clinical cases of hearing impairment and the appearance of tinnitus against the background of new coronavirus infection. At the moment, information on the direct effect of the SARS-CoV-2 virus on the auditory and vestibular analyzer is insufficient and scattered, which requires further observation with subsequent detailed analysis of the results.

280 patients with COVID-19 were examined (average age 53.9±8.1 years; gender index 1.37:1.0 (162 men and 118 women). It was revealed that young people (especially women) were more common with a mild course of the disease (64.2%), middle – aged people-with a moderate-severe variant of COVID-19 (54.8%), In the group of patients with a severe course of coronavirus infection, female patients prevailed among the elderly, and among middle –aged men – 47.8% and 48.4%, respectively. The comorbid background before the disease CAVID-19 and the neurological complications that appeared on the background of CAVID-19 in the percentage ratio prevailed in males. There were no significant differences in the frequency of complications from the severity of the COVID-19 disease. It was revealed that at the time of hospitalization, all the studied markers of coagulation activity were changed and statistically significantly differed from the reference interval, which indicated the activation of the procoagulation potential. In the group of female patients, these indicators were more pronounced. CT examination revealed that the percentage of damage to both lungs was significantly higher in female patients compared to male patients.

It becomes apparent that the neurological complications of COVID-19 are significantly common, but in some cases, establishing a causal relationship is difficult. For example, a stroke can occur for reasons unrelated to coronavirus infection, while Guillain–Barré syndrome and meningoencephalitis are likely to be a parainfection. Only long-term epidemiological studies in large groups of patients can clarify some of these issues. This will help to better understand the mechanisms of development of complications and develop schemes for their treatment and subsequent rehabilitation. The article presents the mechanisms of penetration of the coronavirus into the nervous system and systematizes the neurological manifestations and complications of COVID-19, which were described in the first 3 months of the pandemic. Particular attention is paid to the consideration of the complications of COVID-19 from the central and peripheral nervous system, the most interesting clinical examples are considered. Summing up the analysis of the literature, we can say that the clinical picture of neurological diseases and syndromes caused by coronavirus infection corresponds to the usual notions. Also considered is the assumption that SARS-CoV-2 can persist for a long time in the central nervous system in the form of inactive fragments, which means that it can recur in predisposed individuals when appropriate conditions arise. This suggestion is alarming regarding distant neurological complications in infected and cured patients.

Coronavirus Infection

Infections of the central nervous system (CNS) infections are critical problems for public health. They are caused by several different organisms, including the respiratory coronaviruses (CoVs). CoVs usually infect the upper respiratory tract causing the common cold. However, in infants, and in elderly and immunocompromised persons, they can also affect the lower respiratory tract causing pneumonia and various syndromes of respiratory distress. CoVs also have neuroinvasive capabilities because they can spread from the respiratory tract to the CNS. Once infection begins in the CNS cells, it can cause various CNS problems such as status epilepticus, encephalitis, and long‐term neurological disease. This neuroinvasive properties of CoVs may damage the CNS as a result of misdirected host immune response, which could be associated with autoimmunity in susceptible individuals (virus‐induced neuro‐immunopathology) or associated with viral replication directly causing damage to the CNS cells (virus‐induced neuropathology). In December 2019, a new disease named COVID‐19 emerged which is caused by CoVs. The significant clinical symptoms of COVID‐19 are related to the respiratory system, but they can also affect the CNS, causing acute cerebrovascular and intracranial infections. We describe the possible invasion routes of coronavirus in this review article, and look for the most recent findings associated with the neurological complications in the recently published literature.

Objective ‒ to highlight the high probability and features of neurological complications in patients with COVID-19 pneumonia.Materials and methods. A retrospective cohort study was done of 57 patients with COVID-19 pneumonia who were treated at the COVID-location of the Department of Vascular and Minimally Invasive Neurosurgery and Neurology of the Clinical Emergency Hospital of Lviv in the period from June 29 to September 28, 2020 (91 day).Results. Out of the 57 patients 14 (24.6 %) were selected by prospective analysis that had a clear association between COVID-19 pneumonia and neurological complications. Neurological complications of COVID-19 were manifested as ischemic stroke in 57.1 % of patients, encephalopathy with convulsions and without seizures ‒ in 35.7 %, polyneuropathy with tetraparesis, secondary purulent-inflammatory lesions of the spine ‒ in 7.2 %. Neurological complications occurred on average (20. 4 ± 6.1) days after the onset of the disease.Conclusions. Lesions of the spine and structures in the spinal canal after coronavirus infection had a significant spread along the axis of the spine and severe course. The largest (57.1 %) was the proportion of ischemic stroke in the structure of neurological complications of COVID-19, which indicated the severity of the coronavirus infection and its aggressive effect on the nervous system. The effectiveness of treatment of COVID-19 neurological complications depends on the urgency of hospitalization of patients, as evidenced by the correlation between favorable treatment outcomes and the time from disease onst to admission to either therapeutic (r = + 0.37) or neurological department (r = +0.32).

Respiratory Viral Infections

Based on the example of seasonal epidemics of respiratory viral infections, it is partially possible to model the outcomes of neurological complications from Covid‑19, taking into account the pathogenetic features of the virus effect on the vascular wall and nerve cells. The accumulated experience of doctors of various specialties makes it possible to prevent such life-threatening complications as ACVA, PATE, intoxication, and sepsis. From the first days of the disease, it is necessary to conduct dynamic monitoring of blood rheology, the level of systemic oxygenation, use anticoagulants in preventive doses in patients at the early stages of the disease, conduct therapy aimed at reducing the risk of cytokine storm development.
