Background: Comprehensive studies on transmission from asymptomatic patients are difficult to conduct, as they require testing of large population cohorts and more data are needed to better understand and quantified the transmissibility of SARS-CoV-2. WHO is working with countries around the world, and global researchers, to gain better evidence based understanding of the disease as a whole, including the role of asymptomatic patients in the transmission of the virus. An asymptomatic laboratory confirmed case is a person infected with COVID-19 who does not develop symptoms. Asymptomatic transmission refers to transmission of the virus from a person, who does not develop symptoms. The virus can cause a range of symptoms mild illness to pneumonia. Symptoms of the disease are cough, fever, sore throat, rhinorrhoea, loss of smell, loss of taste, diarrohea, headaches and others. Aim of the study: The study aim was to assess the epidemiology and clinical course of asymptomatic COVID-19 infection in patient. Materials and methods: This prospective observational study was conducted in the Department of Medicine, 250 Beded District Sadar Hospital, Sunamgonj, Bangladesh during the period from June 2020 to August 2020. Eighty two (82) patients diagnosed with asymptomatic COVID-19 infection were included in this study as the study population. Collected data were entered in a predesigned case report form and subsequently analyzed by SPSS 22. Results: The total study population was 82 patients, 61 (74.39%) were males and 21 (25.61%) were females. Table I demonstrated the Sex distribution of the study population.Clinical course of asymptomatic COVID-19 infection in patient. (n=82). The Figure I shows of Symptoms following RT-PCR become positive among the study population 51(62.19%) patients had Cough develop after ± 3days (mean duration), 30(36.58%) patients had Fever developed after ± 6days (mean duration), 23(28.04%) patients had Sore Throat developed after ± 3days .............
