Yes, it does. The shape of the cells and arrangement of receptor proteins dictates which receptor arrangements viruses can infect. No virus can just infect everything.

Also, stop putting two spaces after periods like a boomer. That was something people were taught during the time of typewriters - modern kerning makes it unnecessary and a single space is roughly the same length after a period as two spaces on a typewriter, where the period didn't not advance the carriage a full space's distance.
