Abstract
Background: An outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant was detected in the psychiatric ward of a general hospital in Brasília, Brazil.
Methods: We report the investigation, clinical outcomes, viral sequencing, and control measures applied to outbreak containment.
Results: The overall attack rate was 95% (23/24) in a period of 13 days. Among the cases, 78% (18/23) were vaccinated and 17% (4/23) required intensive care. The Omicron variant was isolated from the 19 sequenced samples.
Conclusions: The findings highlight the potential harm that highly transmissible variants may generate among hospitalized populations, particularly those with comorbidities.

{{ 배경: }} 브라질 브라질리아에 있는 종합병원 정신병동에서 중증급성호흡기증후군 코로나바이러스 2(SARS-CoV-2) 오미크론 변종 발병이 감지되었습니다.
{{ 방법: }} 우리는 발병 억제에 적용된 조사, 임상 결과, 바이러스 염기서열 분석 및 통제 조치를 보고합니다.
{{ 결과: }} 전체 공격률은 13일 동안 95%(23/24)였습니다. 이 중 78%(18/23)는 예방 접종을 받았고 17%(4/23)는 집중 치료가 필요했습니다. Omicron 변이체는 19개의 시퀀싱된 샘플에서 분리되었습니다.
{{ 결론: }} 연구 결과는 입원 인구, 특히 동반 질환이 있는 인구 사이에서 전염성이 높은 변이체가 생성할 수 있는 잠재적인 피해를 강조합니다.
