SARS-CoV-2 was the name given to the triggering virus, and COVID-19, or novel coronaviruse-19, was given to the disease. Since the genome sequencing of SARS-CoV-2 is identical to bat CoV RaTG13, this strain is most likely from bats. To lower the rate of transmission people should avoid public gathering, wear masks, self-hygiene is must. Cold, cough and fever are the early symptoms of the infection. If a person is sick should start self- quarantine in the house itself or consult to the doctor for further diagnosis of COVID-19 disease. RT-PCR and CT scan are the best methods to detect the virus in the body. If the person is infected sever it might take longer time for the recovery and called long-COVID-19. Vaccinations have been started in the countries to reduce the effect of virus and decrease the transmission of virus. Keywords---COVID-19, CoV RaTG13, RT-PCR and CT.
