Abstract
Summary In 1985, 213 serum samples were collected from inhabitants of the village of Ambinda, Haut-Ogooue province in Eastern Gabon and tested by indirect immunofluorescence for Congo-CHF, Rift Valley fever (RVF), Ebola, Lassa and Marburg viruses. No antibody against Congo-CHF or Marburg, 0.9% against Lassa and 1.4% against RVF were detected in these sera, but 10.3% of sera had antibodies against Ebola virus. They were particularly reactive against the Ebola-Zaire isolate (9.4%), whereas only 0.9 % reacted with the Ebola-Sudan isolate. These results are comparable to those from Cameroon and the Congo, but not as high as those found in Zaire, Sudan, Chad and the Central African Republic. They confirm that Ebola virus is widespread in Central Africa, and that its activity in this province has slightly increased since 1980.
