ABSTRACT
OBJECTIVE: To determine the prevalence of OD in the confirmed case with COVID-19 among our population using quick smell identification test (Q-SIT) as screening tool. METHODS: Cross- sectional study carried out in Qatif area-Saudi Arabia among adult hospitalized patient with confirm COVID-19 during the period between May and July, 2020. All adults confirmed COVID-19 patients were interviewed for history of current disease and associated symptoms as well as performing Q-SIT. Participants who had history of olfactory dysfunction, and critical cases required ICU admission were excluded. RESULTS: The prevalence of OD among COVID-19 cases was (16.3%) in our population using Q-SIT compared to (27.4%) for self-reported symptom. Females were having higher prevalence in compare to males (30.5% and 11.1%) respectively; which was statistically significant (P < 0.001). The patients reported higher prevalence of ageusia (31.9%) with significant association with OD (P < 0.001). Q-SIT showed high positive and negative predictive value in detecting OD among patients with COVID-19 (84% and 93% respectively). CONCLUSION: Q-SIT is a useful, validated and easy to apply tool for screening OD among patients with COVID-19. Some patients presented solely with this symptom which can occurs unnoticed in COVID-19 patients, and there for required objective test for detection.
ABSTRACT
BACKGROUND: The first case of COVID-19 infection in Saudi Arabia was reported in Qatif on March 2nd, 2020. Here, we describe the clinical characteristics of the initial COVID-19 patients in that area. METHODS: This is an observational study describing the clinical presentation, radiographic and laboratory data of COVID-19 cases. RESULTS: From March 1st, 2020 to April 5th, 2020 we identified a total of 82 adult COVID-19 patients. The median age of the patients was 50 years, with a range of 30 to 60 years and most of patients were female 54 (65.9%). Of all the patients, 29 (35.4%) were contacts and 43 (52.4%) were returning travelers, mainly from Iraq (65% of the total returning travelers). Comorbidities were present in 50% of patients, G6PD deficiency in 33%, hypertension in 27%, and diabetes mellitus in 26%. Chest radiographs were abnormal in 46% of symptomatic and 15.5% of asymptomatic patients (P value = 0.0035). Of all patients, 4 (4.87%) required intensive care admission. There was no significant difference in time to negative RT-PCR with mean days to negativity of 13.6 and 16.9 for asymptomatic and symptomatic group, respectively (P value = 0.42). CONCLUSIONS: In the initial Epicenter of the COVID-19 in Saudi Arabia, the majority of the patients were asymptomatic and were returning travelers. Comorbidities were present in nearly half of the patients.
