Answer

Thrombocytopenia is a recognized complication after infection with Epstein-Barr virus, varicella virus, cytomegalovirus, rubella virus, or hepatitis virus (A, B, or C). However, the most typical association is with a vaguely defined viral upper respiratory infection or gastroenteritis.

Transient thrombocytopenia has been reported to be associated with recent immunization with attenuated live-virus vaccines. [35, 36]
