• Coronavirus can cause diseases in mammals and birds.
• Coronavirus can cause respiratory infections in human.
• The name "coronavirus" is derived from the Latin corona, meaning crown or
halo, which refers to the characteristic appearance of the virus particles
(virions).
• Coronaviruses were discovered in the 1960s.

5.
• Viral particles can transmit through air drop lets or droplet nuclei.
• Incubation period of this virus is approximate 14 days .
• Coronaviruses are zoonotic, meaning they are transmitted between
animals and people.

6.
• Fever
• Cough
• Shortness of breath
• Breathing difficulties
• Pneumonia
• Severe acute respiratory syndrome
• kidney failure and even death

7.
• Viral particles can detect through electron microscopy
• PCR finger printing

8.
• Regular hand washing, covering mouth and nose when
coughing and sneezing can prevent spreading of viruses.
• Eating of cooking meat and eggs.
• There are no vaccines or antiviral drugs that are approved for
prevention or treatment.
