Doctor's Notes on Yellow Fever
Early symptoms of yellow fever may be similar to malaria, dengue fever, or other viral hemorrhagic fevers. Symptoms of yellow fever may include sudden high fever, chills, prominent backache and headache, appetite loss, nausea or vomiting, and occasionally a slow heartbeat. About 15% of patients will develop a second, more severe, stage of illness with symptoms including high fever, abdominal pain, nausea and vomiting, and development of jaundice (yellowing of skin and eyes). Other symptoms may include spontaneous bruises and bleeding due to abnormal blood coagulation from the eyes, nose, mouth, needle puncture sites, as well as upper and lower gastrointestinal tract with blood in vomit and stool. Abnormal blood levels of liver enzymes and kidney failure may occur.
