Paragraph on Coronavirus or COVID-19 | Short School Essay on Coronavirus or COVID-19
Coronaviruses get their name from their shape. These round viruses are surrounded by a halo of spiky proteins. That makes them look a bit like a crown or the corona of the sun.In fact, being termed a coronavirus “is less about the genetics and more about the way it appears under a microscope,” explains Brent C. Satterfield.
People are not the original source of coronavirus diseases. SARS, MERS and COVID-19 are zoonotic. That means that people originally catch the virus responsible from some animal.
Two of the most well-known of the deadly types are responsible for SARS and MERS. Each of these diseases has caused global outbreaks in the past. In December 2019, another virus joined these dangerous cousins. Scientists are calling it SARS-CoV-2.
On February 11, the World Health Organization started calling the disease this new virus triggers COVID-19. That stands for coronavirus disease in 2019.
These coronaviruses cause severe infections by first latching onto proteins that sit on the outside of lung cells. Those attachments help the viruses penetrate far more deeply into the airways than their cold-causing kin.COVID-19 is a disease that causes more lung disease than sniffles.Coronaviruses have been making people cough and sneeze for eons. They are among the many viruses that cause the common cold. But not all are so mild-mannered.
The incubation period of COVID-19 is thought to be between one and 14 days. It is contagious before symptoms appear, which is why so many people get infected.Infected patients can be also asymptomatic, meaning they do not display any symptoms despite having the virus in their systems.
