Herpesvirus infections are neglected

In sub-Saharan African herpesvirus infections are widespread, yet outside of some specific disease presentations (Kaposi's Sarcoma, Burkett's Lymphoma and HSV-1/2 genital warts) they have been under-researched. We seek to network herpesvirus researchers to bring about collaborative research studies in patient populations in Africa, where there is a high burden of HIV, Tuberculosis, malnutrition, and other diseases of poverty. We promote basic science, observational and epidemiological studies, as well as diagnostic and therapeutic development and intervention.

Herpesvirus basics

There are nine herpesvirus species for which humans are the natural reservoir. They cause a diverse set of diseases affecting a broad range of tissues and organ systems. Primary infection results in life-long latent infection with periodic reactivations which are more common for some species than others. Disease presentation often differs between primary infection and reactivation, or re-infection with different strains. Herpesviruses are well established as causal pathogens in many well characterised diseases which result from direct pathology of the virus in a specific tissue or organ, but they are also associated with several neurological conditions and malignancies, where the exact causal mechanisms are less clear. There is a long and expanding list of conditions in which herpesviruses may play a causal role, and one of the greatest challenges to the herpesvirus researcher or practitioner, is to differentiate active infections causing pathology which might respond to treatment, from sub-clinical infections.

These findings add to previous data suggesting HCMV is an important determinant of the health of African children. PDF
