TopIntroduction
COVID-19 is a novel coronavirus that causes a highly contagious illness. It was found in Wuhan, China, at the end of 2019. The WHO (World Health Organization) declared the virus a global hazard in January 2020. The virus affects people in a variety of ways. Older persons and other persons with chronic illnesses are more vulnerable to severe disease (Worldometers-COVID-19). As a result, governments, health systems, and their limited resources have been put under a lot of strain. The global death rate is gradually increasing which is a cause for concern. Transmission is divided into four phases based on the dissemination technique and the time frame. Each nation implemented various methods to counteract the spread of the disease, including sitting at home, face masking, reducing travel, shunning social gatherings, handwashing routinely, and sterilizing the environment (Sujath et al., 2020). The WHO received reports of 290,959,019 confirmed COVID-19 cases as of January 4, 2022, with a total of 5,446,753 fatalities. 8,693,832,171 vaccination doses have been distributed since January 2, 2022.
The spread of the disease poses significant hazards to human life and civilization. There is currently no precise remedy for the pandemic, and several antiviral drugs, plasma transfusions, and other medications have been examined in the clinical field with caution (Muhammad et al., 2020). The coronavirus outbreak in India has affected societal functioning. Everyone was advised to social distancing to escape the dreadful transmission. Cases that have been confirmed are those that have come back from overseas in the early stages, followed by local transmission. A lot of infections are caused by the present COVID-19 outbreak due to severe acute respiratory syndrome worldwide (SARS-CoV-2). Governments and public healthcare systems are under tremendous stress as infection and death rates rise exponentially. Identifying significant mortality determinants is necessary to maximize patient treatment strategies. The COVID-19 death rate was also thought to be strongly correlated with hospital capacity; the higher the death rate, the lower the hospital capacity. As a result, individuals at increased mortality risk must be prioritized (Sujatha and Chatterjee, 2020; Du et al., 2020; Chen et al., 2020, Aljameel et al., 2021; Ko et al. 2020). A total of 28 blood biomarkers, as well as gender and age attributes, were selected using analysis of variance (ANOVA) and available data. An assembly strategy was utilized to achieve a specificity value of 0.91, sensitivity of 1, and accuracy value of 0.92 by combining a deep neural network and Random Forest models to increase the number of patient points and the researchers also developed an online web tool (BeatCOVID-19) that forecasts mortality using blood test data which could benefit from data upgrades (Khan et al., 2021; Dhamodharavadhani et al., 2020). Planning for considerable increases in the capacity of standard hospital beds and intensive care unit (ICU) beds in the event of a pandemic is essential to enable patient identification and speedy isolation procedures (Phua et al., 2019).
