The U.K. variant in particular, which the CDC has said spreads "more quickly and easily than other variants," seems to replicate more efficiently, Lopman said. A new strain occurs when a virus goes through one or more mutations that change its behavior in some way, but a variant develops when a virus goes through a mutation of any kind, explained Dr. Patricia Couto, an infectious disease physician at Orlando Health in Florida. Earlier Coronavirus Strains Earlier in 2020, when the pandemic was new, you might have heard that there … Coronaviruses are named for the crown-like spikes on their surfaces.
