Fifth Disease

Apparently my 1-year-old nephew has Fifth disease, poor baby :( 
My sister took him to the doc today and told her he's fine, he was contagious a week and a half ago, and the only concern is if he's had any contact with a pregnant woman- yes, me! I'm 24+3, and have regular contact with my nephew
In waiting on a call from my doc office to ask about what that could mean to me, but in the meantime, has anyone dealt with this before?
 Anyone been exposed to Fifth disease while pregnant? 
Any insight would help!
