COVID-19 pandemic: A literature review

Abstract

Corona virus disease (COVID-19) is an infectious disease caused by a newly discovered corona virus. Most people infected with the COVID-19 virus will experience mild to moderate respiratory illness and recover without requiring special treatment. Older people and those with underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop serious illness. The first case of COVID-19 in India, which originated from China, was reported on 30 January 2020. India currently has the largest number of confirmed cases in Asia, and has the second-highest number of confirmed cases in the world after the United States, with more than 9 million reported cases of COVID-19 infection and more than 100 thousand deaths. By mid of 2020, India had approached in position of conducting highest number of daily tests in the world which subsequently translated to a high number of positive cases. The per day cases peaked mid-September in India with over 90,000 cases reported per day and have since come down to below 40,000 in December [1].
