Complete Blood Count (CBC) in COVID-19 Patients Attending at Bangladesh Institute of Health Sciences (BIHS) General Hospital, Dhaka, Bangladesh

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is the infectious agent that causes Coronavirus Disease 2019 (COVID-19), a contagious illness. The epidemic has continued since it was first discovered in Wuhan, Hubei, China, in December 2019. The WHO estimated that 800 million people worldwide (or one in ten) may have COVID-19 infection on October 5. More than 1.07 million fatalities and 37 million cases have been documented as of October 11, 2020, spanning 188 nations and territories; more than 25.7 million patients have recovered. Fever, coughing, exhaustion, shortness of breath or other breathing issues, and a loss of taste and smell are typical symptoms. Acute respiratory distress syndrome (ARDS), which can be brought on by cytokine storm, multi-organ failure, septic shock, and blood clots, can affect some people while the majority only have moderate symptoms. One to fourteen days may pass during the incubation period. The aim of this study was to observe the Complete blood count in COVID-19 & Non COVID-19 Patients in Bangladesh. A descriptive cross-sectional study was conducted for the study. Data were collected from Bangladesh Institute of Health Sciences (BIHS) General Hospital and Hematology Department of Bangladesh University of Health Sciences (BUHS). A pretested semi-structured questionnaire was used for the data collection. The standard method of diagnosis is by real-time reverse transcription polymerase chain reaction (RT-PCR) from a nasopharyngeal swab. The results showed that, among 100 patients, 50% patient was Covid-19 positive &50% patient was negative. In comparison between Covid-19 positive & negative CBC result showing that Hb% remain almost same, total count is slightly increased in covid-19 positive patient than non-covid-19. RBC are found in Normal range for both positive and negative patients. Platelet count & PCV are lower in Covid-19 positive patient than negative patient. Neutrophil are significantly raised in Covid-19 positive patient. Lymphocytes are significantly decreased in Covid-19 positive patient than negative. In this study males are affected 64% & females are 36% so the ratio between male& female is 3:2. More positive patients were found in the age between 50-70 years & has risk among 40-80 years. According to this study, it can be concluded that there is an association among neutrophil, lymphocyte and other cell status in clinically in COVID-19 & non COVID-19 Patients.
