However, in November 2019, a more lethal strain of the coronavirus family was discovered in Wuhan, China. This virus was genetically of the same coronavirus family but was not known before. It was thus named – severe acute respiratory syndrome coronavirus – 2 (SARS-CoV-2) and the disease it caused is called the ‘novel coronavirus disease’ or ‘COVID 19’.
The virus SARS-CoV-2, which causes COVID 19 has been discovered for the first time. Though the symptoms of COVID 19 are similar to the seasonal flu; scientists and doctors have been studying flu for decades. There is no element of surprise in the flu as in the case of COVID 19. Less or absolutely no knowledge about its treatment or how long is it going to stay, makes COVID 19 make more lethal than any other disease.
Another most important factor that makes COVID 19 dangerous is that it is highly communicable from human to human. An infected person can transmit the virus to a healthy person by just a normal touch of a hand. The virus SARS-CoV-2 is also capable of settling over a surface for three to four days and for three to four hours in the air.
