Introduction:
Investigating the effectiveness of infection control in health care facilities is of paramount importance, given the critical role of health care facilities in preventing the spread of infectious diseases.

Aim:
The aim of this article is to comprehensively analyse the infection control system in a specified health facility and identify key deficiencies that contributed to the spread of SARS-CoV-2.

Material and methods:
Statistical analysis and epidemiological surveillance methods were used in the study. The analysis revealed significant systemic problems in the existing infection control system at the perinatal centre, covering various aspects, including lack of adequate quarantine measures, insufficient regular testing, incorrect medical records and organizational failures.

Results and Discussion:
During the study, the following results were obtained: 22.2% of the perinatal centre staff and 15.5% of patients were infected with COVID-19 during the study period. The main factors contributing to the high rate of infection were the lack of systematic testing (only 30% of the staff underwent regular PCR testing), inadequate quarantine measures (40% of cases were not isolated), and deficiencies in medical record keeping and contact tracing (only 20% of contacts of infected persons were recorded).

Conclusions:
These factors combined to create a favourable environment for the spread of the virus within the institution.
