How can a disease transition from a basic illness to a flown blown pandemic​
eimsori [14]

Answer:

Pandemics occur for two reasons. The first is a change in the infectious agent and the second is in human patterns. Both involve exposing people to agents they don’t have resistance to.

Examples of the second are when new groups of humans make contact, like small pox amongst native Americans, and possibly the black death.
