One of the most fatal diseases encountered by mankind so far is Ebola fever. Ebola fever is caused by a highly pathogenic virus from the Filoviridae family which is found in nature in four different sub-types which differ among others also by their pathogenicity for man. The hitherto detected EBO sub-types are stable do not change in the course of an epidemic nor in the course of the patient's illness, nor during passage of the virus from one subject to another. The author presents a historical review of epidemics, nosocomial and laboratory infections, spread and epizoonosis caused by the Ebola virus. The author presents a detailed clinical picture describing the frequency and evolution of different clinical symptoms and signs based on the observation of 103 patients infected with the Ebola virus in Kikwit, Zaire (nowadays Democratic Republic of Congo) in 1995. In the laboratory diagnosis individual tests are mentioned assessing the presence of the virus, viral antigens and antibodies, incl. the most recent immunohistochemical test. The author mentions the problem of patient care and his therapy, incl. available antiviral drugs and passive immunotherapy. He also discusses the possibility and probability of spread of the Ebola virus into our environment. He mentions principles for transport of subjects with suspected disease, demands for their strict isolation and maximum protection of the attending staff incl. barrier nursing technique. The author discusses also principles of epidemiological work, detection and isolation of sources, identification and follow up of contacts and epidemiological supervision of affected areas. Past epidemics made it possible to assemble many scientific findings and practical experience. These make it possible to cope nowadays with any attack of the Ebola virus not only in areas of its epizootic occurrence. |
