The coronavirus 2 (SARS-CoV-2) (COVID-19) pandemic has stimulated an unprecedented response by the global scientific community to better understand the disease. However, many questions about SARS-CoV-2 remain unanswered. Various hypotheses have been formulated in regard to its pathogenetic mechanisms.

COVID-19 — это новое появившееся инфекционное заболевание человека, ознаменовавшее начало третьего десятилетия XXI века. Новый коронавирус, вызывающий COVID-19, получил обозначение «коронавирус тяжелого острого респираторного синдрома 2» (SARS-CoV-2) [21]. Впервые о нем сообщили в городе Ухань, Китай, и он быстро распространился по стране, вызвав эпидемию. COVID-19 затронул почти все страны мира и был зарегистрирован среди людей всех возрастов, включая детей [27]. 11 марта 2020 года ВОЗ объявила COVID-19 пандемией, которая позже была описана ВОЗ 23 марта как «ускоряющаяся пандемия», когда количество случаев заболевания превысило 350 000 [24].

Коронавирус инфекцияси соғлиқни сақлаш тизимида ҳалигача долзарб муаммоларни юзага келтирмоқда. Касалликнинг тез ва кенг тарқалиши амалиёт шифокорлари ҳамда соҳа олимлари учун ўз навбатида қатор муаммоларни юзага келтирмокда.

Four years have passed since WHO declared the coronavirus a pandemic. During this time, the disease claimed the lives of 6.8 million people. The SARS CoV 2 virus is highly variable and is expected to disappear over time, becoming an endemic infection similar to other respiratory infections. Corneal transplantation is a surgical treatment aimed at restoring the optical and structural properties of a pathologically altered cornea. Exogenous and endogenous causes can lead to transplant rejection, a sharp decrease in vision and subsequent impairment of the patient's ability to work.
