Infectious diseases pose a threat to human life and could affect the whole world in a very short time. Corona-2019 virus disease (COVID-19) is an example of such harmful diseases. COVID-19 is a pandemic of an emerging infectious disease, called coronavirus disease 2019 or COVID-19, caused by the coronavirus SARS-CoV-2, which first appeared in December 2019 in Wuhan, China, before spreading around the world on a very large scale. The continued rise in the number of positive COVID-19 cases has disrupted the health care system in many countries, creating a lot of stress for governing bodies around the world, hence the need for a rapid way to identify cases of this disease. Medical imaging is a widely accepted technique for early detection and diagnosis of the disease which includes different techniques such as Chest X-ray (CXR), Computed Tomography (CT) scan, etc.

For example, Chennai-based Xcode Life Sciences is notably India's first bioinformatics company to introduce a DNA-based anti-aging skincare program for women. The program is known as Come Alive and is one of the most successful and promising bioinformatics companies in the country. The company also provides other services such as Gene Health -- a health module that identifies genetic markers of diabetes, obesity and heart conditions leading to preventive care and treatment. The genomics company first made news for launching its innovative DNA Ancestry test that allows people to trace their ancestry by matching it with more than 35 ethnic groups in India and other groups across the world and also the most recent paternal ancestor.
