COVID 19
Corona viruses are a group of related viruses that cause diseases in mammals and birds. In humans, corona viruses cause respiratory tract infections that can range from mild to lethal. Mild illnesses include some cases of the common cold while more lethal varieties can cause SARS, MERS, and COVID-19. Symptoms in other 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. Corona viruses constitute the subfamily Ortho corona virinae, in the family Corona viridae, order Nidovirales, and realm Riboviria.They are enveloped viruses with a positive-sense single- stranded RNA genome and a nucleocapsid of helical symmetry. The genome size of corona viruses ranges from approximately 26 to 32 kilo bases, one of the largest among RNA viruses. They have characteristic club-shaped spikes that project from their surface, which in electron micro graphs create an image reminiscent of the solar corona from which their name derives.
