Demographic and Clinical Characteristics Associated with COVID-19 Infection in Hormozgan Province, Iran Between January 24 to June 10, 2020

Abstract

Background: Coronavirus disease 2019 (COVID‐19) caused by severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) infection has been widespread. Objectives: We aim to investigate the demographic and clinical characteristics associated with COVID-19 infection between January 24 to June 10, 2020. Methods: All data related to tested patients (positive and negative cases) were extracted from the integrated health information system (IHIS) between January 24 to June 10, 2020. Statistical analyses were performed using data related to the anamnesis of all patients, odds ratios (OR) of COVID-19 infection in defined subgroups including contact history, partial pressure of oxygen (PO2) higher than 93 mmHg, the muscle-pain symptom, the cough symptom, and the fever symptom. Results: The COVID-19 infection was significantly associated with contact history (OR 5.25, [95% CI 4.35 to 6.34], P-value < 0.0001); PO2 higher than 93 mmHg (OR 1.74 [95% CI 1.44 to 2.22], P-value < 0.0001); muscle-pain symptom (OR 1.89 [95% CI 1.58 to 2.26], P-value < 0.0001); cough symptom (OR 1.32 [95% CI 1.14 to 1.53], P-value < 0.0001); and fever symptom (OR 1.29 [95% CI 1.11 to 1.49], P-value = 0.0004). Conclusions: The results of our study indicated that contact with patients or suspicious individuals can be considered as the most important symptoms of COVID-19 disease. Furthermore, the high pressure of oxygen, muscle-pain, cough, and fever symptoms were identified as considerable symptoms of COVID-19 disease.
