- vdernov 11y agoVarying levels of infectivity are at least one reason why some viruses are easier to get infected by. They work via different mechanisms, like different cellular receptors, and this also plays a role. Etc...

So, it appears they are at least common enough that we're all passing along endogenous viral elements[2] to our children (and we got them from our parents).
