Background: There are different types of viruses found in nature which cause infection in
humans and other animals, some causing severe illness and others not. A unique coronavirus termed severe
acute respiratory syndrome coronavirus-2 (SARS-CoV-2) was isolated from lower respiratory tract
sample as the causative agent.
Objective: This review article includes characteristics of COVID-19, current scenario of disease, causes
and symptoms of disease and how to prevent from its infection.
Methods: We accomplished a comprehensive evaluation of the communication amid COVID-19 disease
and serious effects of the disease. There are many articles describing the general characteristics, prevention
and its harmful effects on humans which were included. The clinical diagnosis and present scenario
of the disease were also reviewed.
Results: The recent outbreak of contagions with SARS-CoV-2 is termed Coronavirus Disease 2019
(COVID-19) by the World Health Organization (WHO). Many governments of the world, scholars and
scientists are engaged to discover the proper treatment and until a proper and right treatment for it is
found, we have to be careful to avoid infection.
Conclusion: At present, the whole world is struggling with COVID-19 disease. COVID-19 quickly
spread into at least 215 countries and exterminated more than 300,000 persons by May 15, 2020. This is
the time to exercise restraint and caution. The rapid extent of disease allows deep examination and quarantine
conventions to prevent further transmission.
