I have rosacea and my dermatologist thinks it might be an increase in demodex mites. Treatment has been horrible because my skin is also sensitive to the creams I get for treating it. She's put me on a pill regime to fight it that way. Thankfully it's not contagious (though everybody has demodex, it's just the amount of them).

I'd talk to your pdoc soon, though, before you fall down the rabbit hole any further.
