Abstract:
:WHILE THE TWENTIETH CENTURY HAS PRODUCED GREAT DEVELOPMENTS IN THE EPIDEMIOLOGY OF YELLOW FEVER AND IN TECHNIQUES FOR ITS CONTROL IN URBAN AREAS, THE ESSENTIAL METHOD OF CONTROL HAS NOT CHANGED: it is still the elimination of the urban vector, Aëdes aegypti. The aim of those responsible for yellow fever control in Africa should be the eradication of this vector from all urban communities in the endemic area. In the case of sylvan yellow fever, complete control of the vectors is not yet possible, but mass immunization of the human population at risk is feasible. The solution of the yellow fever problem in Africa lies in the accomplishment of these two aims.
