INTRODUCTION: Yellow fever is a non-contagious infectious disease, highly 
lethal, transmitted by the Aedes, Haemagogus and Sabethes.
METHODS: Descriptive retrospective study of the yellow fever cases in Amazonas, 
between 1996 and 2009.
RESULTS: Forty two cases of yellow fever were confirmed, with 30 deaths, 10% of 
which were foreigners.
CONCLUSIONS: The presence of Aedes aegypti and Aedes albopictus in both rural 
Amazonas and its capital demonstrates the dispersion of these vectors and 
underscores the need for better and continuous epidemiological and entomological 
control.
