In children, most cases of ITP are acute, and onset seems to occur within a few weeks of recovery from a viral illness. The severity of symptoms of the viral illness does not correlate with the degree of thrombocytopenia.

Thrombocytopenia is a recognized complication after infection with Epstein-Barr virusvaricella viruscytomegalovirusrubella virus, or hepatitis virus (AB, 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. [36, 37]
