Prevalence of COVID-19 Positive Cases Diagnosed By Real Time Polymerase Chain Reaction and Mortality from SARS-Cov-2 among Suspected Population
Main Article Content
Abstract
SARS-CoV-2, a newly emergent virus is the responsible agent for causing Corona Virus Disease 2019 (COVID-19) which is an outgoing pandemic. Test for SARS-CoV-2 is necessary not only to confirm the cases but also to control its transmission. To diagnose Covid-19, Real Time Polymerase Chain Reaction (RT-PCR) for SARS-CoV-2 is used. A retrospective, cross sectional research was conducted in Brahmanbaria Medical college to find out the prevalence of RT-PCR positivity in suspected COVID-19 patients presented from July, 2021 to August, 2021 in the Department of Microbiology. Data was collected from the registry book of the Department of Microbiology. Among the total suspected samples (n=2025), about 1145 (56.54%) cases found positive. Among the positive cases, 59% were symptomatic, and 41% were asymptomatic. Out of the total confirmed cases, 487 (42.53%) were male & 658 were (56.54) % female. Among the confirmed cases, total recovery cases were 1057 (92.3 %) and death cases were 88 (7.7%). More death was observed in age group between 51-60 years. More than half of the positive cases with a medium number of asymptomatic population indicate a high chance of disease transmission. Female being the more vulnerable group of getting infected and age group above 50 years were more prone to succumb.
