Coronavirus was first discovered in 1960, but its exact origin is not yet known. Rather, it is a virus that can infect both humans and animals. A total of six strains of this virus have been identified today, while the now heavily prevalent strain worldwide, the seventh strain, is therefore referred to as the "untreated" virus. "New coronavirus" and later officially named "COVID-19" (COVID-19), therefore, the new coronavirus and COVID-19 refer to the same virus.

Thank you for coming in and reading.

Its a virus that affect human immune system causes fever,lungs problem, difficulties in breathing and severed cough, so without adequate treatment it will lead to death.
