How Does COVID-19 Work?


(WUTR-TV) — The World Health Organization describes COVID-19 is an infectious disease that attacks the respiratory system. The spikes you see on the outside of the virus attach to the cells in the respiratory track, then highjacks the nucleus and reproduces itself.

“Thousands of copies of itself and in doing so it kills the epithelium cells, the epithelium cell then basically pops open but then you have all of these viral particles and they just go and find other epithelium cells and the process goes over and over and over again.” – Dr. Kent Hall Chief Physician Executive, MVHS

By then your body knows that something bad is going on, so it begins making antibodies.

“So, your body says this is a foreign protein, it is not supposed to be here so I’m going to make something that will neutralize it.” – Dr. Kent Hall Chief Physician Executive, MVHS

During your body’s natural defenses, it can affect the heart and blood vessels and cause them to leak.

“Fluid tends to leak out of the blood vessels into the tissues. Which is why you get fluid that collects in the lungs, fluid that can collect around the heart and people with kind of serious infections can become bloated everywhere.” – Dr. Kent Hall Chief Physician Executive, MVHS

Dr. Hall says the virus’ goal is to make as many copies of itself as possible.

“But it is in the making of more itself and our bodies response to that, that causes the disease which is COVID-19.” – Dr. Kent Hall Chief Physician Executive, MVHS
