Primary immune thrombocytopenia is associated with multiple factors that may lead to loss of self-tolerance to the antigens on the surface of platelets and megakaryocytes. Several infectious agents have been implicated. Herpes viruses due to the high prevalence in the population and tropism by the lymphoid cells have been related to the development of this entity. A bibliographic review was made using search engines such as Ebsco and Pubmed that allowed access to related articles in magazines arbitrated. Information was collected and organized that involved the role of cytomegalovirus and EBV infection in the development of ITP. Most of the articles indicate that in these viruses, the non-cytolytic nature of replication favors the time of interaction and modulation on host cells that are frequently B, T and natural killer lymphocytes. Timely diagnosis and appropriate therapy in these patients contributes to the immunomodulation of self-reactivity and viral elimination, in the light of current knowledge, is essential for integrated clinical treatment. Consider monitoring the serological and molecular status of these herpes viruses in patients in whom the natural history of the disease suggests their association, especially in primary or secondary immune thrombocytopenia; by the high level of relation of the mechanisms of production of the autoimmunity, the dysmielopoyesis and the lymph proliferation with the pathogenesis of the infection by these viruses.
