My granddaughter was recently diagnosed with fifth disease or slap cheek. This is a very common childhood illness. Since I have Polycythemia vera though, I decided to do a little research about that disease to make sure I could be around her safely. Here is what I learned about that:
Parvovirus infection (fifth disease - slap cheek) in people with anemia may stop the production of red blood cells and cause an anemia crisis. People with sickle cell anemia are at particular risk.
I am totally ignorant about medical/biology but reading this, I can’t help but wonder if this parvovirus could somehow be manipulated to fight polycythemia vera.
