Factors Preventing Nosocomial Outbreak Following a Single case of COVID-19 Diagnosed During Hospitalization: A
1Department of Respiratory and Critical Care Medicine, Inje University Seoul Paik Hospital, Seoul, Korea.
Objective:
Our hospital experienced a hospital shutdown and 2 week quarantine after a case of COVID-19 was diagnosed during hospitalization. We analyzed the reopening process following hospital closure and possible factors that prevented hospital spread.
Methods:
We retrospectively reviewed the confirmed patient's medical records and results of epidemiological survey available from the infection control team of our hospital.
Results:
A total of 117 hospital staff members were tested, 26 of whom were self-isolated. Of the 54 inpatients tested, 28 on the same floor, and 2 close contacts in the endoscopic room were quarantined in a single room. Finally, all quarantined hospital staff, inpatients and outpatients were tested for COVID-19 on the 14th day of close contact. The results were all negative, and the hospital work resumed completely.
Conclusion:
Although closing and isolating the hospital appeared to have played a useful role in preventing the spread of COVID-19 inside the hospital and to the local community, it is still debated whether or not the duration of hospital closure or quarantine was appropriate. The lessons from the 2-week hospital closure suggest that wearing a mask, hand hygiene and the ward environment are important factors in preventing nosocomial outbreaks of COVID-19.
