Background. Coronavirus disease-19 (COVID-19) is a new type of coronavirus that has caused a global pandemic. The disease is highly contagious, and all people are susceptible to the disease. Therefore, extensive measures were taken to prevent the spread of the disease at the community and hospitals. This study aimed to investigate the impact of COVID-19 outbreak on nosocomial infection rate. Methods. This cross-sectional study was conducted in an educational hospital, southeast Iran. The nosocomial infection rates of critical/intensive care units (CCU/ICUs) and medical-surgical units were assessed during and before the COVID-19 outbreak. Results. There was a 19.75-point decrease in the total rate of nosocomial infection during the COVID-19 outbreak ( = 0.02). In addition, there was a 39.12-point decrease in the total rate of CCU/ICUs’ nosocomial infection during the COVID-19 outbreak ( < 0.001). A 19.23-point decrease was also observed in the total rate of medical-surgical units’ nosocomial infection during the COVID-19 outbreak ( = 0.13). All kinds of CCU/ICUs’ nosocomial infections had between 31.22- and 100-point decreases during the COVID-19 outbreak. Among medical-surgical units, 33.33- and 30.70-point decreases were observed only in UTI and SSI, respectively, during the COVID-19 outbreak, while BSI had a 40-point increase during the COVID-19 outbreak. Conclusions. Proper implementation of infection control protocols during the COVID-19 pandemic seems to reduce nosocomial infections.

COVID-19 爆发对医院感染率的影响：以伊朗为例

背景。冠状病毒病 19 (COVID-19) 是一种新型冠状病毒，已引起全球大流行。该病具有高度传染性，所有人都易患该病。因此，采取了广泛的措施来防止疾病在社区和医院传播。本研究旨在调查 COVID-19 爆发对医院感染率的影响。方法。这项横断面研究是在伊朗东南部的一家教育医院进行的。在 COVID-19 爆发期间和之前评估了重症/重症监护病房 (CCU/ICU) 和内外科病房的医院感染率。结果。在 COVID-19 爆发期间，总医院感染率下降了 19.75 个百分点（ = 0.02)。此外，在 COVID-19 爆发期间，CCU/ICU 的医院感染总发生率下降了 39.12 个百分点（ <0.001）。在 COVID-19 爆发期间，内外科单位的医院感染总比率也下降了 19.23 个百分点（ = 0.13）。在 COVID-19 爆发期间，各类 CCU/ICU 的院内感染下降了 31.22 至 100 点。在 COVID-19 爆发期间，在内外科单位中，仅 UTI 和 SSI 分别下降了 33.33 和 30.70 点，而 BSI 在 COVID-19 爆发期间增加了 40 点。结论。在 COVID-19 大流行期间正确实施感染控制协议似乎可以减少医院感染。
