Yellow Fever | Pathogenesis (mosquitoes, virus), Signs & Symptoms, Diagnosis and Treatment

This video tutorial covers yellow fever, a hemorrhagic fever caused by Flaviviridae viruses. It discusses the transmission through mosquitoes, particularly Aedes aegypti and Haemagogus species, and highlights risk factors like travel to endemic areas. The pathogenesis involves viral replication in the liver, spleen, and lymph nodes, leading to symptoms in three stages: infection, remission, and intoxication.
