The article states that President Biden received Paxlovid treatment after his diagnosis of COVID infection. The article doesn’t explain anything about Paxlovid itself.

So, Why Do I Care??  At the time of writing this blog post the number of COVID infections numbered 765 million with 6.78 million deaths worldwide.  There is a small number of people (less than 1% of infections) who suffer serious health consequences, and even die because of this virus. Early intervention, such as the use of oral antiviral drugs is a promising way to prevent the development of serious illness.  The way Paxlovid acts may provide a template on how antiviral drugs may treat other virus-borne illnesses.

Plain English, Please!!!

First, let’s talk about why corona viruses can cause so much damage to our bodies. Corona viruses is an organism that can not multiply without a cell hosting it. In order to multiply, corona viruses hijack the RNA making and the protein-making capacities of the host cell.  Viral hijacking means that the host cell can not make RNA and proteins for the host’s own use, and the host cell dies as a consequence of the infection. Therefore, the main direct damage from corona virus infection is the killing of our own cells.

Second, let’s talk about how Sars-CoV-2 hijacks cells. Once a corona virus enters a living host cell, the long RNA of the virus snatches the ribosomes of the host cell, and is transcribed into a long, viral
