Epidemiological Notes on Some Viruses Isolated In Uganda (Yellow fever, Rift Valley fever, Bwamba fever, West Nile, Mengo, Semliki forest, Bunyamwera I Ntaya, Uganda S and Zika viruses)
(1952)During a period of 10 years (1937-1947) 10 different viruses were isolated at the Yellow Fever Research Institute (now Virus Research Institute), Entebbe, Uganda. Two of these, yellow fever and Rift Valley fever virus, ... -
Genetic selection of a flavivirus-refractory strain of the yellow fever mosquito Aedes aegypti
(2014)Two inbred (isofemale) Aedes aegypti mosquito lines were derived that manifested a resistant or susceptible phenotype following ingestion of yellow fever virus; lack of virus movement from the midgut defined the resistant ... -
Investigation surrounding a fatal case of yellow fever in Côte d'Ivoire in 1999
(2014)Côte d'Ivoire is an endemic country for yellow fever, but no case was officially notified in recent years. In July 1999, however, one fatal case was reported. A German citizen was infected in the national park of Comoe, ... -
Laboratory infection with Zika virus after vaccination against yellow fever
(2014)One of the authors contracted a Zika virus infection during laboratory work. Subsequent studies revealed an immunological response of the anamnestic type due to preceding yellow fever vaccinations which rendered difficult ... -
Limitations of the complement-fixation test for distinguishing naturally acquired from vaccine-induced yellow fever infection in flavivirus-hyperendemic areas
(2014)On the basis of previous studies, it has long been stated that 17D yellow fever (YF) vaccine generally does not induce complement-fixing (CF) antibodies, and that the presence of CF antibodies could be used in epidemiological ... -
A multipurpose serological survey in Kenya. 2. Results of arbovirus serological tests
(1970)Arbovirus infections are of public health interest in East Africa, where a very widespread epidemic of o'nyong-nyong fever was reported in 1959-60 and where the threat of yellow fever, present in neighbouring areas such ... -
Risk assessment for yellow fever in western and North-Western provinces of Zambia
(2015)Background: North-Western and Western provinces of Zambia were reclassified as low-risk areas for yellow fever (YF). However, the current potential for YF transmission in these areas is unclear. Aims: To determine the ... -
Serological and entomological study on yellow fever in Sierra Leone
(2014)In a serological and entomological survey on yellow fever carried out in Sierra-Leone in 1972, altogether 899 sera from children 0 to 14 years were tested with 12 antigens by haemagglutination-inhibition and complement ... -
Vectors of the 1969 yellow fever epidemic on the Jos Plateau, Nigeria
(2014)Entomological investigations of the possible mosquito vectors of the yellow fever epidemic on the Jos Plateau, Nigeria, were carried out between 27 October and 15 November 1969.Of the 5 species of Aedes (Stegomyia) collected, ... -
Yellow fever and Zika virus epizootics and enzootics in Uganda
(2014)Data of monkey serology are presented which, together with past evidence, support the view that yellow fever (YF) virus circulates in its primary sylvan host populations, i.e., forest monkeys, in an enzootic state in Bwamba ... -
Yellow fever monoclonal antibodies: type-specific and cross-reactive determinants identified by immunofluorescence
(2014)Monoclonal antibodies directed against the envelope glycoprotein and the NV3 non-structural viral protein of yellow fever (YF) were tested by the indirect fluorescent antibody technique against a variety of YF virus strains ...
