Abstract
Aim – to study the course of the acute period of infection caused by SARS-CoV-2 in healthcare workers in comparison with individuals not engaged in medical activities.
Material and methods. A cross-sectional online study was conducted from June to September 2022. To study the frequency of COVID-19 episodes in healthcare workers and individuals of other professions, an internet resource (testograf.ru) was used, based on which anonymous online questionnaires were posted. The questionnaire included three blocks of questions: information about the patient; data on previous NCI and vaccination; data on the recovery period of NCI (presence of complaints, period of occurrence and their duration). The analysis included 22,535 individuals who had COVID-19.
Results. In general, during this period, healthcare workers were characterized by a more frequent registration of pneumonia (22.6% vs. 20.5%, p = 0.0002) and the need for oxygen support (6.7% and 5.1%, p < 0.0001), the presence of complicated course (7.3% vs. 6.9%, p = 0.2506). Despite the similarity of the clinical picture during the period of circulation of various strains of NCI, features of the clinical course were revealed depending on the circulating predominant strain. The effectiveness of the vaccination against COVID-19 was revealed during the period of dominance of the “Wuhan” and “Delta” genetic variants and the lack of effectiveness during the period of dominance of “Omicron”.
Conclusion. A feature of our study was the presentation of data using an internet resource, which allows us to fully reflect the objective reality in the framework of morbidity among healthcare workers. The study revealed the features of the clinical course in healthcare workers.
