Fifths : Fifths disease is a common, relatively harmless viral infection - most often seen in kids and characterized by red cheeks followed by a lacy rash on the arms, legs and body. Some people will also have fever for a day or two. It typically resolves on its own without treatment. The only time we really worry about this virus is if it infects someone who is pregnant or someone with a chronic blood disease such as sickle cell anemia, thalessemia, or spherocytosis. The virus can stop the bone marrow from producing red blood cells for a short period of time. This does not usually affect a healthy person, but can affect someone who's red blood cells are not normal in the first place. I attached a website with more information about fifths disease. If she has a chronic blood disease, if her paleness continues, or if she is acting sick at all, give her doctor a call. Good luck!
