Abstract

This cross-sectional descriptive study aimed to determine the prevalence of COVID-19 infection and to analyze the association between sociodemographic characteristics and clinical symptoms with RT-PCR test results among patients attending the fever clinic at Vajira Hospital. Medical records of patients who visited the clinic between April 1 and July 31, 2021 were reviewed. A total of 390 cases were included in the study. Data were analyzed using the chi-square test and logistic regression.


The results revealed that the prevalence of COVID-19 infection among the sample was 11.8% (46 cases). Sociodemographic factors such as gender, age, and occupation were not significantly associated with RT-PCR results. However, certain clinical symptoms showed a statistically significant positive association with RT-PCR positivity, including tachycardia (heart rate>100 bpm; OR=2.554, p=0.047), tachypnea (respiratory rate>20 breaths/minute; OR=5.051, p=0.005), sore throat (OR=4.962, p=0.002) and productive sputum (OR=54.234, p<0.001). Although symptoms such as elevated body temperature (>37.5°C), cough, myalgia, runny nose, dyspnea, headache, loss of appetite and anosmia were more frequently observed among COVID-19 positive patients, no statistically significant associations were found with RT-PCR results in this study.
