К шестой категории кожных проявлений коронавирусной инфекции ученые относят крапивницу, которая в некоторых случаях может быть предвестником начала COVID-19 . К последней (седьмой) категории можно отнести артифициальные (трофические) изменения тканей лица, возникшие у пациентов с искусственной вентиляцией легких и из-за длительного лежания на животе. Приведенные классификации были первыми описаниями поражений кожи при COVID-19 и поэтому приводились разные признаки: те, что были вызваны именно COVID-19 , и те, которые возникали вследствие различных причин, в частности, связанных с лечением заболевания. В связи с тем, что эти поражения нуждались в различных подходах как в лечении, так и в проведении противоэпидемических или мер предосторожности, мы, исходя из опыта всех этих месяцев наблюдения за больными, предлагаем классификацию поражений кожи, ассоциированные с COVID-19 . выложить следующим образом

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.

Skin lesions in coronavirus infection caused by the SARS-CoV-2 virus are divided into seven categories. The first category includes skin angiitis caused directly by COVID-19 infection, against which the walls of small vessels of the dermis are damaged by immune complexes circulating in the blood. Angiitis is localized on the skin of the upper and lower extremities. They look like frostbite, painful, itchy. Such manifestations usually occur in young patients with a mild course of the disease, appear in the late stages and last about 12 days. The second category includes papular-vesicular rashes, which are characterized by acute clinical manifestations in the form of chickenpox, more similar to prickly heat, occurring against a background of high fever and increased sweating.

At present, the risk of increased circulation of vaccine-related polioviruses and associated outbreaks with a low level of vaccination coverage against the background of the use of an oral vaccine is also complicated by military operations in the country, leading to the destruction of the infrastructure of cities and towns, intensive migration and evacuation of the population. Ukraine, and to regions where there are no active hostilities (Chernivtsi, Transcarpathian, Lvov, Volyn regions). These areas were the ones with the lowest polio vaccination rates in 2021.
