The new Coronavirus disease or COVID-19 is a contagious viral/immunological systemic disorder with predominantly respiratory features caused by human infection with SARS-CoV-2, which is rapidly spreading from person-to-person all around the world as a pandemic. As long as there is no effective vaccine available to prevent this disease and no definitive treatment is provided to cure it, it is better to prevent this disease by following a series of principles, which are: home quarantine of asymptomatic to mild COVID-19 patients and hospitalization of severe cases, physical distancing, staying at home, handwashing, cleaning and disinfecting high-touch surfaces, face-mask using, cough and sneeze covering, healthy nutritious diet along with the routine life activities and daily exercise, video communication by phone/online with family, and finally practice to relieve stress/anxiety.
