Could all diseases have been airborne at some point in time?

I thought about it after seeing a zombie movie- basically how did the 1st cases of diseases infect people or animals? I want to make sure it isn't possible that before diseases were specifically airborne or contact-based, could they all have been airborne, then evolved into their now present-day counterparts?

No, of course not.  For example, HIV and Hepatitis B/C have always been blood-borne.

I haven't seen anything to suggest that this is the case.  Anywhere. I do get that things evolve, however, usually viruses, bacteria and parasites usually have a pretty defined pathway. They haven't ever changed their mode of transmission.
