"The lining of the respiratory tree becomes injured, causing inflammation," said Wilson.

"This, in turn, irritates the nerves in the lining of the airway. Just a speck of dust can stimulate a cough. But if this gets worse, it goes past just the lining of the airway and goes to the gas exchange units, which are at the end of the air passages. If they become infected, they respond by pouring out inflammatory material into the air sacks that are at the bottom of our lungs," he added.

According to Wilson, if the air sacks develops inflammation, inflammatory material will outpour into the lungs, and will cause pneumonia.

Once the inflammatory material fills the lungs, the lungs loses its ability to get sufficient oxygen to the bloodstream, therefore lowering the body's ability to absorb oxygen and release carbon dioxide.

"That's the usual cause of death with severe pneumonia," he explained.

As of this writing, there is no cure and vaccine against coronavirus but scientists are fast-tracking research to end the crisis caused by the pandemic.

As such, tests such as X-Rays can provide them a clearer insight on the coronavirus.
