False-colour transmission electron micrograph (TEM) of a field of Epstein-Barr virus particles (small, red & gold circular objects). The Epstein- Barr virus (EBV) is 1 of 5 herpes viruses that attacks humans. In Europe & US infection may produce glandular fever; in Central Africa EBV infection may lead to Burkitt's lymphoma (a facial cancer affecting children). In both infections, the virus infects one type of white blood cell, the B lymphocytes. Infection with EBV is common & usually harmless; additional factors potentiate the development of more serious diseases. In the case of Burkitt's lymphoma malaria is a likely cofactor.
