A virus is an infectious submicroscopic creature that only reproduces inside live cells. All living things, including plants, animals, and microbes like bacteria and archaea, are susceptible to virus infection.
Researchers have discovered that some viruses actively seek out the "sugar-coating" on the surface of cells, adhere to, and infect the cell as a result.
All of the body's cells are covered with a thick layer of sugar, one of the most naturally occurring compounds, which shields them against bacterial and viral attacks.
Most infectious bacteria and viruses bind to sugars on the surface of our cells
