A Case of Infectious Mononucleosis with Concurrent EBV and CMV IGM Seropositivity

Infectious mononucleosis is a common viral infection affecting mainly children, adolescents and young adults. Its main aetiology is Epstein – Barr Virus followed by Cytomegalovirus. We present the case of a 26-year old lady, presented with clinical and laboratory features of the disease, with serologic evidence of concurrent EBV and CMV IgM positivity. Whether this represents a simultaneous infection or a previous infection by the one virus, boosted by the sequential infection by the second one, is very difficult to distinct.
