The document summarizes information about COVID-19. It began in Wuhan, China in December 2019, when several cases of an unknown pneumonia were reported. Officials later identified it as a new coronavirus called SARS-CoV-2. It spreads mainly through respiratory droplets when an infected person coughs or sneezes. Common symptoms include fever, cough, and shortness of breath. While 80% of cases are mild, it can cause severe pneumonia and death in some cases, especially among the elderly and those with pre-existing conditions. China has faced over 82,000 cases but has recovered most patients, while the virus has since spread globally.

an envelope with protein spikes. This gives it the appearance
of a crown. The word corona means “crown” in Latin.

5. ZOONOTIC NATURE
Corona viruses are zoonotic, meaning that the viruses are transmitted between
animals and humans. One of the viruses named MERS- CoV was transmitted
through dromedary camels to humans. The source of covid-19 is yet to be
determined, but the investigations are ongoing to identify the zoonotic source to
the out break.
