Spawn Component from class

Is there a blueprint function that lets me spawn a component from class?

if not then
Basically what im trying todo is i’ve created a Master class(Type Actor Component) of diffrent diseases. Then I have made several diseases as children of the main class(Say small pox). I then randomly choose which disease to spawn. Then I send this over to the player pawn and spawn the chosen disease.

So far all of this is working, however their is no way I can take that class type and spawn off of it that I have found. If this was an actor i’d use a constructor, but that doesn’t work in this instance(because constructors will not build components).
