Overview
Causes
PCH can be an after effect of an infection, when a microorganism triggers the formation of antibodies that cross-react with the P antigen on the red blood cell membrane. Viral infections that can cause PCH include measles, mumps, influenza, adenovirus,chickenpox, cytomegalovirus, and Epstein-Barr virus. Bacterial infections that can cause PCH include syphilis,Haemophilus influenzae and Mycoplasma pneumoniae. PCH can also be a side effect of some vaccinations. Chronic idiopathic(of unknown cause) PCH also occurs, but it is rare.
