Outcome of RT-PCR in the Diagnosis of Patients with COVID-19 Symptoms: A Study in a COVID-19 Referral Hospital

Abstract

<i>Introduction: </i>Corona virus (SARS-CoV-2) (COVID-19) outbreak was first reported in China rapidly spread around the world within short period causing global public health emergency. COVID 19 is a highly infectious disease caused by severe acute respiratory syndrome corona virus 2 (SARS-CoV-2). The initial symptoms were fever, cough, dyspnea, myalgia or fatigue, headache, hemoptysis, diarrhea and acute respiratory distress syndrome (ARDS). Hence in diagnosis of COVID-19 RT-PCR of viral nucleic acid is regarded as the reference standard to detect the COVID-19 positive cases. <i>Objective: </i>The aim of this study was to determine the outcome of RT-PCR of the patients with COVID-19 symptoms. <i>Methodology: </i>This was a cross-sectional prospective study carried out in the department of Radiology and imaging in collaboration with the department of Virology and COVID unit in IbnSina Hospital, Dhaka, Bangladesh during January, 2022 to June, 2022. A total of 239 OPD patients with COVID-19 symptoms aged above 18 years were enrolled in this study. The collected data were cleaned, edited and entered into computer for analysis. The data were analyzed using Statistical Package for Social Sciences (SPSS) software, version 23.0. The ethical clearance of this study was obtained from the Ethics Committee of School of Public Health & Life Science, University of South Asia, and Dhaka, Bangladesh. <i>Results: </i>In this study a total of (n=239) patients with COVID-19 symptoms were enrolled. According to age distribution, the majority., 142 (59.42%) patients belonged to the age group >52 years, which was the highest and followed by 44 (18.42%) age group (43-52) years, 36 (15.06%) (33-42) years, 14 (5.85%) (22-32) years and 3 (1.25%) <22 years. According to sex distribution, the majority, 167 (69.85%) were male and 72 (30.12%) were female. Distribution by symptoms, all the patients239 (100%) had general weakness and followed by sneezing 221 (92.46%), fever 236 (98.74%), headache 228 (95.39%), cough 232 (97.07%), respiratory distress, 225 (94.14%), cough and SOB, 237 (99.16%), loss of smell, 212 (88.74%), lac of apatite, 224 (73.72%), asthma 218 (91.21%) and pneumonia, 118 (49.37%). In RT_PCR lab test results, the majority 195 (81.58%) were observed COVID-19 Negative (-) and 44 (18.41%) were observed COVID-19 Positive (+). Among the positive cases, the majority 26 (60%) were male and 18 (40%) were female. <i>Conclusion: </i>This study prevailed around 20 % of the patients with COVID-19 symptoms got COVID-19 Positive in RT-PCR lab test results. Therefore, the patients with COVID-19 symptoms must conduct RT-PCR lab test for their being sure of their COVID-19 affection. At the same time, the male are more vulnerable to COVID-19 than their counter part female.
