Yellow fever
Overview
Yellow fever is a viral infection spread by infected mosquitoes, common in South America and in sub-Saharan Africa. Once bitten, symptoms usually appear within 3 to 6 days, progressing in three stages. In stage 1, infection, symptoms include headaches, muscle and joint aches, fever, flushing, loss of appetite, vomiting, and jaundice. In stage 2, remission, fever and other symptoms go away. In stage 3, intoxication, problems with many organs occur, including heart, liver, and kidney failure, bleeding disorder, seizures, coma, and delirium. Yellow fever can cause severe damage leading to internal bleeding or death.
