В настоящее время риск усиления циркуляции вакцинородственных полиовирусов и связанных с ними вспышек при низком уровне охвата прививками на фоне применения оральной вакцины осложняется еще и военными действиями в стране, приводящими к разрушению инфраструктур городов и населенных пунктов, интенсивной миграции и эвакуации населения. Украины, так и в регионы, где отсутствуют активные боевые действия (Черновицкая, Закарпатская, Львовская, Волынская обл.). Именно в этих областях отмечались самые низкие уровни вакцинации против полиомиелита в 2021 году.

Considering that a similar picture took place in previous years, in Ukraine there was an accumulation of a layer susceptible to poliomyelitis among the child population. In addition, since April 2016, the oral (live) polio vaccine (OPV), which is used in Ukraine, since the 3rd vaccination, does not contain type 2 poliovirus (two-component OPV, which is now used worldwide, contains only polioviruses). ). type ov1 and 3). This also contributes to a decrease in both individual and population immunity to type 2 poliovirus. The result was an outbreak of poliomyelitis caused by vaccine-derived type 2 poliovirus (a vaccine-derived virus that acquired neurovirulent properties during circulation in a low immune population.). There was no adequate response to this outbreak, namely additional vaccination rounds for children under 6 years of age to stop the circulation of the vaccine-related virus. In January 2022, a new outbreak emerged.

Moreover, low vitamin D levels common in patients with CVD may increase the risk and severity of COVID-19. This is because vitamin D increases levels of anti-inflammatory cytokines and reduces viral replication, which in turn can reduce pro-inflammatory cytokines that contribute to lung damage. Despite the lack of evidence demonstrating increased susceptibility to COVID-19, drugs used in the treatment of COPD increase the risk of respiratory tract infections to varying degrees. However, theoretically, some immunosuppressive drugs may have beneficial effects, given that the cause of death in COVID-19 is a cytokine storm leading to acute respiratory failure.

The last (seventh) category includes artificial (trophic) changes in facial tissues that occurred in patients with artificial lung ventilation and due to prolonged lying on the stomach. The classifications given were the first descriptions of skin lesions in COVID-19 and therefore different signs were given: those that were caused specifically by COVID-19, and those that arose due to various causes, in particular those associated with the treatment of the disease. Due to the fact that these lesions required different approaches in both treatment and anti-epidemic or precautionary measures, we, based on the experience of all these months of observation of patients, propose a classification of skin lesions associated with COVID-19. lay out like this
