4. Saliva
Saliva can easily spread parvovirus and cause others to become ill. Salvia carries the virus, and when a person talks, spits or even breathes, the virus can be sent out into the air. A person nearby can breathe it in and become infected. Most people don’t realize that they release saliva when they talk. If an infected person uses a straw or glass and then an uninfected person drinks after them, they can also be infected.
This is why parvovirus is so easily transmitted within families’ workspaces, schools, and daycare centers. The saliva left on the straw or glass may contain enough of the virus to cause an infection. If a person is aware they are contagious, they may avoid talking to someone directly, but with parvovirus, the symptoms don’t appear until after a person is no longer contagious. By the time they realize they are sick, they could have passed the virus along to other people.
