Epidemiological evidence for causal relationship between Epstein-Barr virus and Burkitt's lymphoma from Ugandan prospective study

Results from a prospective sero-epidemiological study initiated in Uganda in 1971 indicate that children with high antibody titres to Epstein-Barr virus structural antigens are at high risk of developing Burkitt's lymphoma. These findings strongly support a causal relationship between the Epstein-Barr virus and Burkitt's lymphoma but suggest that the oncogenic potential of the virus is realised only in exceptional circumstances.

Is Burkitt's lymphoma related to perinatal infection by Epstein-Barr virus?

Burkitt's lymphoma (B.L.) is very restricted geographically, whereas the Epstein-Barr virus (E.B.V.), a very likely causal factor, exists all over the world. It is proposed that perinatal infection (either transplacental, or, more probably, neonatal) is an important risk factor for the development of B.L. This hypothesis arose when the epidemiological characteristics of E.B.V. infection were compared in different parts of the world and is supported by the preliminary results of a seroepidemiological prospective study of B.L. E.B.V. would behave in a manner similar to that of animal tumour viruses whose oncogenic potential is greatly enhanced by neonatal infection.
