Aim: COVID-19 has led to a global crisis not only in the health sector but also in the economic, social and education sectors, as well as the lives of common man. This paper reviews the origin, characteristics and transmission of the SARS-CoV-2 Virus and the preventive measures adopted by the world's nations to curb the effects of the pandemic. Subjects and methods: The temporal and spatial profile of the COVID-19 spread is highly dynamic and is progressively changing at a rapid pace. This article is an attempt to mitigate the pandemic threat by sharing the review outcome from an extensive literature survey on recent articles on COVID-19 and its impact. Results: Statistical analysis presented by the World Health Organization and other health organizations explicitly indicates that optimized support and care extended to infected persons is the key to therapy, and the clinical effectiveness of alternative techniques is still under study. Though there have been announcements on the discovery of drugs for the virus, the authenticity of these reports are yet to be verified. Conclusion: Based on the review, it can be inferred that it is important to boost one's immune system and to stay healthy by developing healthy habits of food intake, sleep, exercise, personal hygiene and so on. Practicing social distancing with a self-motivated attitude will help to control the virus to a large extent. The current situation also demands a great sense of responsibility of people towards society by protecting oneself from the virus in order to protect the society one lives in.
