This document compares and contrasts yellow fever and dengue fever. Both diseases are acute infectious diseases caused by flaviviruses and transmitted by the bite of the Aedes aegypti mosquito. The document outlines the different signs and symptoms of each disease, with yellow fever causing jaundice and dengue fever causing muscle and joint pain. It also discusses the diagnostic tests used to identify each virus, including blood and complex tests.
