It can take two to 14 days for a person to develop symptoms after initial exposure to the virus, Hirsch said. The average is about five days. it begins infecting epithelial cells in the lining of the lung. A protein on the receptors of the virus can attach to a host cell's receptors and penetrate the cell. Inside the host cell, the virus begins to replicate until it kills the cell.
This first takes place in the upper respiratory tract, which includes the nose, mouth, larynx and bronchi.

As the virus continues to replicate and journeys further down the windpipe and into the lung, it can cause more respiratory problems like bronchitis and pneumonia, according to Dr. Raphael Viscidi, Pneumonia is characterized by shortness of breath combined with a cough and affects tiny air sacs in the lungs, called alveoli. The alveoli are where oxygen and carbon dioxide are exchanged. When pneumonia occurs, the thin layer of alveolar cells is damaged by the virus. The body reacts by sending immune cells to the lung to fight it off.

Restricting oxygen to the bloodstream deprives other major organs of oxygen including the liver, kidney and brain. In a small number of severe cases that can develop into acute respiratory distress syndrome (ARDS), which requires a patient be placed on a ventilator to supply oxygen.
However, if too much of the lung is damaged and not enough oxygen is supplied to the rest of the body, respiratory failure could lead to organ failure and death.

Deply concern by the alarming levels of spread severity and the levels of inaction.

the virus can spread person-to-person within 6 feet through respiratory droplets produced when an infected person coughs or sneezes. It’s also possible for the virus to remain on a surface or object, be transferred by touch and enter the body through the mouth, nose or eyes.

Viscidi stresses that outcome is uncommon for the majority of patients infected with coronavirus. Those most at risk to severe developments are older than 70 and have weak immune responses
