The first case of pneumonia of unknown origin was identified in Wuhan, the capital city of Hubei Province situated in the Republic of China. The pathogenic organism that has been identified as a causative organism is a novel enveloped RNA betacoronavirus, which has been designated as severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). This virus has been found to have a similar phylogeny to SARS-CoV. The novel coronavirus or COVID-19 can be symptomized through clinical manifestations like pyrexia or fever, cough, dyspnea/difficulty in breathing, myalgia/muscle pain, and constant fatigue. COVID-19 can be transmitted through respiratory tract secretions. It mainly results in respiratory tract infections and the development of severe pneumonia in infected patients. Severe disease may ultimately cause death due to progressive respiratory failure. The coronavirus disease 2019 or COVID-19 has been declared a public health emergency of international proportions by the World Health Organization (WHO). Thus, an analysis of cases might help in the identification of the disease's defining clinical characteristics, association with underlying lifestyle habits, and disease severity. This present article studied the probability of smoking and alcohol consumption in increasing the risk involved in increasing the severity of COVID-19 infection among affected subjects.
