BACKGROUND: Coronavirus disease 2019 is an emerging highly communicable disease. Nosocomial transmission needs to be prevented through the implementation of stringent screening and infection control measures. OBJECTIVE: The objective of the study is to estimate the prevalence of severe acute respiratory syndrome– coronavirus 2 (SARS-CoV-2) infection among health care workers (HCWs) post quarantine period. METHODS: This is a prospective, observational study conducted at a teaching University hospital in Alkhobar, Saudi Arabia, during the period between May 1 and June 15, 2020. All (HCWs) joining work back from the quarantine areas had a real-time polymerase chain reaction (qRT-PCR) test for SARS-CoV-2. The demographic and clinical data from the staff were collected. RESULTS: Of the 301 HCWs screened, 18 (6%) had positive PCR. The age means of the positive cases was 32.9 Y ± 8.7 compared to 33.8 Y ± 7.0 in the negatively tested group (p value = 0.90). Of the 18 PCR-positive HCWs, 7 (38.9%) were male. Majority of those who tested positive were trainees (8.2%) followed by nurses (5.1%). In PCR-positive group, a clear epidemiological exposure was found in 4/18 cases (22.2%). Male gender and residency in specific districts were observed more in the positive cases (p value = 0.01 and 0.0001, respectively). In regards to symptoms, most of the positive PCR tested HCWs (n=12, 66.7%) remained asymptomatic. Most prevalent initial symptoms were gastrointestinal symptoms (diarrhea, abdominal pain) in six HCWs representing 33.3%. No significant difference was noted in co-morbidities reported by both groups. CONCLUSION: Health care workers tested post-quarantine period were found to be at risk of SARS-CoV-2 infection despite very minimal or no known risks of exposure, where most of them were asymptomatic. This potentially carries risk of nosocomial transmission inside healthcare facilities. Implanting policies for routine post-quarantine screening for HCWs is recommended.
