Coronavirus has spread all over the world today, all countries are trying to control this virus, most of the countries have locked themselves down so that the coronavirus can be prevented from spreading because there is no medicine for coronavirus yet. Many countries are working fast on making coronavirus medicine. Hopefully, coronavirus medicine will be available soon. Coronavirus will come in contact with each other in humans. It thrives and its symptoms start appearing in 1 to 14 Days.

Coronaviruses are a group of related viruses that cause diseases in mammals and birds. In humans, coronaviruses cause respiratory tract 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 SARS, MERS, and COVID-19. Symptoms in other species vary: in chickens, they create 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 coronavirus infections. Coronaviruses constitute the subfamily Orthocoronavirinae, in the family Coronaviridae, order Nidovirales, and realm Riboviria. They have enveloped viruses with a positive-sense single-stranded RNA genome and a nucleocapsid of helical symmetry. The genome size of coronaviruses ranges from approximately 26 to 32 kilobases, one of the largest among RNA viruses. They have characteristic club-shaped spikes that project from their surface, which in electron micrographs create an image reminiscent of the solar corona from which their name derives.
