Exposure to a virus doesn't ensure infection - there is some probability involved, depending at least partially on the number of virus particles that you are exposed to, over what period of time. Viral load is literally a numerical expression of the quantity of virus in a given volume. It is often expressed as viral particles, or infectious particles per mL depending on the type of assay. And a higher viral load often correlates with the severity of an active viral infection. |
