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.
The use of thiopurine (azathioprine and mercaptopurine) reduces the immune response to viruses, which is associated with an increased risk of opportunistic infections. There is limited evidence that they increase the risk of respiratory infections. The risks and benefits should be considered, but most patients can continue on a stable dose. In patients in stable remission, elderly patients and in the presence of concomitant pathology, it is recommended to stop taking thiopurine. During a pandemic, it is recommended to avoid starting thiopurine or increasing the dose, which will allow patients to avoid potential side effects. If the patient is in contact with a COVID-19 person, temporary withdrawal of thiopurine for 2 weeks should be considered. If a patient tests positive for SARS-CoV-2 and/or develops COVID-19, temporary discontinuation of thiopurine may be recommended until the patient clears the infection.
Реагирование на такие эпидемические вызовы очень сложны как организационно, так и финансово. Результат оценивается с течением времени при хорошо организованном эпидемиологическом надзоре. Согласно утвержденному плану реагирования на вспышку полиомиелита, возникшему в начале октября 2021 г., удалось только 1 февраля 2022 г. начать 1-й тур кампании. Он должен был длиться 3 недели и имел целью вакцинировать ИПВ 140 тыс. детей в возрасте от 6 мес. до 6 лет, пропустивших вакцинацию согласно Календарю. Практически к концу 3-й недели 1-го тура по состоянию на 18.02.2022 г. было провакцинировано лишь 28% детей от запланированного количества. Поэтому решили продлить 1-й тур еще дополнительно на 2 недели, что снова не было исполнено в связи с началом войны. Таким образом, фактически реагирования на вспышки полиомиелита не произошло.
On March 11, 2020, the World Health Organization declared the novel severe respiratory syndrome coronavirus (SARS-CoV-2) a pandemic. The number of cases worldwide is constantly growing, the infection is a serious threat to health, especially in the case of old age, immunodeficiency and the presence of concomitant diseases. There are now a growing number of reports and preliminary observations indicating that the COVID-19 virus can also infect the skin. Skin lesions ranging from "covid fingers" to hives can be potential signs of coronavirus. The flow of information about the skin manifestations of coronavirus infection prompts the development of a classification of these lesions.
