Viral diseases in Ethiopia: a review.

Ethiopia is endemic for many viral diseases. Serosurveys have demonstrated the high prevalence rate of hepatitis B virus. There are also indications of high transmission for hepatitis C, hepatitis E and human immunodeficiency virus (HIV). The population is exposed to poliomyelitis, hepatitis A, measles, rubella and mumps early in life. Rotaviral diarrhoea is an important cause of infant morbidity and mortality. Vast areas of the country are endemic for yellow fever and rabies. The extent of many other viral diseases in the country is unknown. There is a need for a well organised national laboratory to assess the impact of vaccination efforts and to support control as well as surveillance measures within the country.
