Corona Virus

This virus are a group of related viruses that cause diseases in mammals and birds. In humans ,corona viruses cause respiratorytract infections that can range from mild to lethal.Mild illnesses include some cases of the common cold (which has other possible causes, predominantly rhinoviruses)while more lethal varieties can cause SARA,MERS, and COVID-19.Symptoms in others species vary: in chickens, they cause an upper respiratory tract disease, while in cows and pigs they cause diarrhea. There are yet to be vaccines or antiviral drugs to prevent or treat human corona virus infections. Coronaviurses constitute the subfamily Orthocoronavirinae,in the family Coronaviridae, order Nidovirales, and realm Riboviria. They are enveleped viruses with a positive-sense single -stranded RNA genome and a nucleocapsid of helical symmetry. The genome size of coronaviurses ranges from approximately 26 to 32 kilobases .


Coronaviruses were first discovered in the 1930s when an acute respirstory infection of domesticated chickens was shown to be caused by infectious bronchitis virus (IBV) Arthur schalk and MC Hawn described in 1931a new respiratory infection of chickens in North Dakota. The infection of newborn chicks was charactrized by gasping listlessness. In 1937,Fred Beaudette and charles Hudson reported that they had sucessfully isolated and cultivated the infectious bronchitis virus which caused the disease. In the 1940s two more animal coronaviruses , mouse hepatitis virus (MHV) and transmissible gastroenteritis virus (TGEV)were isolated.


Corona viruses first reported in china,wuhan.
