In the initial events, the Kingdom of Saudi Arabia implemented mandatory quarantine of returning travelers in order to contain COVID-19 cases. Materials and methods: This is a longitudinal study of the arriving travelers to Quarantine facilities and the prevalence of positive SARS-CoV-2 as detected by RT-PCR. Results: During the study period, there was a total of 1928 returning travelers with 1273 (66%) males. The age range was 28 days–69 years. Of all the travelers, 23 (1.2%) tested positive for SARS-CoV-2. Of the first swab, 14/1928 (0.7%) tested positive. The positivity rate was 0.63% and 0.92% among males and females, respectively (P = 0.57). The second swab was positive in 9 (0.5%) of the other 1914 who were initially negative with a positivity rate of 0.39% and 0.62% among males and females, respectively (P = 0.49). There was no statistical difference in the positivity rates between first and second swab (P = 0.4). Of all travelers, 40 (n = 26, 1.3%) were admitted from the quarantine facility to the hospital due to COVID-19 related positive results or development of symptoms such as fever, cough, and respiratory symptoms; and 14 (0.7%) were admitted due to non-COVID-19 related illness. Conclusion: This study showed the efforts put for facility quarantine and that such activity yielded a lower incidence of positive cases. There was a need to have a backup healthcare facility to accommodate those developing a medical need for evaluation and admission for non-COVID-19 related illnesses.en-USPublic Health EmergencyCOVID-19QuarantineTravelSaudi ArabiaIncidence of COVID-19 among returning travelers in quarantine facilities: A longitudinal study and lessons learnedArticle
