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.
"It was an ordinary day, a cold morning. I was sleeping after a night shift and woke up from the fact that massive shelling had begun. A tank unit of 16 tanks approached us. Our armored personnel carrier was shot down before my eyes and I ran to help pull the guys out, but did not I ran a little, there were about seven meters left, I could hear the whistle of shells, explosions and darkness ... I rubbed my eyes from the ground and saw that there was a bare bone in the place of the arm, I thought that I should see what was happening with my legs, if I could move. "I thought that I would die, but I was lying, I realized that I would not die for a long time, that I would live and I had to do something, and I put on a tourniquet," the military man says.
Experts refer to the third category of skin manifestations as pink lichen and papulosquamous rashes, which are infectious-allergic skin lesions associated with COVID-19 infection. The clinical feature of pink lichen in this case is the absence of maternal plaque. The fourth category includes a measles rash. To the fifth - toxicodermia. This rash is associated with individual intolerance of patients of certain groups of drugs. The sixth category of skin manifestations of coronavirus infection, scientists include urticaria, which in some cases may be a harbinger of the onset of COVID-19.
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.
