What are common symptoms of yellow fever?

The symptoms of yellow fever primarily include headache, jaundice, fever, vomiting, and bleeding, which directly reflect the impact of the virus on the body. Yellow fever is a viral disease transmitted by mosquitoes, and its symptoms often manifest within 3 to 6 days after infection.

Headache is a common early symptom that can develop alongside a high fever. Jaundice, indicated by the yellowing of the skin and eyes, occurs when liver function is impaired due to the virus. Vomiting can be severe and may contain blood, indicating gastrointestinal bleeding as the disease progresses. This bleeding can also result from liver damage, leading to other hemorrhagic symptoms such as nosebleeds or bleeding from the gums.

This physiological response underscores the seriousness of yellow fever, distinguishing it from other illnesses that may present with less severe symptoms. Understanding these symptoms is crucial for early identification and intervention, especially in areas where yellow fever is endemic.
