Normaly neither. A virus is an infectious agent that needs a living cell to make more viruses. Otherwise, a virus just floats around. Some viruses do need carbohydrates to be made, but without a cell a carbohyrate is useless. To some extent, though, certain carbohydrates help a virus by powering the cell that builds viruses. Putting it simply, a lone carbohydrate will most likely do nothing to a lone virus.

smiley? most likely
