Yellow fever has been subjected to partial control for decades, but
there are signs that case numbers are now increasing globally, with the
risk of local epidemic outbreaks. Dengue case numbers have also
increased dramatically during the past 40 years and different serotypes
have invaded new geographical areas. Despite the temporal changes in
these closely related diseases, and their enormous public health impact,
few attempts have been made to collect a comprehensive dataset of their
spatial and temporal distributions. For this review, records of the
occurrence of both diseases during the 20th century have been collected
together and are used to define their climatic limits using remotely
sensed satellite data within a discriminant analytical model framework.
The resulting risk maps for these two diseases identify their different
environmental requirements, and throw some light on their potential for
co-occurrence in Africa and South East Asia.
