Threat of Marburg and Ebola viral haemorrhagic fevers in Africa.
Marburg and Ebola viruses are members of the filovirus family that can be regarded as recently emerged. These viruses have caused sporadic outbreaks of fatal haemorrhagic disease in Africa, Europe and recently in the USA. The case fatality rates rank among the highest ranging from 33-80%. The mode of transmission of these viruses are clearly through close contact with blood and body fluids. Disease outbreaks have been amplified in hospital situations with poor blood precautions. In villages disease has been amplified through contamination with blood and fluids during nursing the sick and burial rituals. The source of the viruses has eluded discovery and new theories regarding the nature of these viruses are being entertained. The threat of new outbreaks in Africa is real since serological evidence of the presence of the virus has been documented in Kenya, Sudan, Zaire, Zimbabwe, Gabon, Cote-d'Ivoire and Gabon.
