The disease is caused by the virus severe acute
respiratory syndrome, previously referred to as the
NOVEL CORONAVIRUS (2019-nCOV).
it is primarily spread between people via respiratory
droplets from coughs , sneeze. The lungs are the
organs most affected by COVID-19 because the
virus accesses host cells via the enzyme ACE2
which is the most abundant in the type II alveolar

glycoprotein called spike to connect to ACE2 in
each tissue correlates with the severity of the
disease.
