What is yellow fever?

Yellow fever is an acute viral haemorrhagic fever. Caused by a Flavivirus and transmitted by infected Aedes Aegypti mosquitoes. It’s name is derived from its jaundice (yellowish colouration of the eyes) in some infected individuals.



This virus incubates in the body for 3 to 6 days once it is contracted before its symptoms begin to show. They include headaches, muscle aches, joint aches, chills, fever, loss of appetite, and nausea or vomiting.

In most cases, symptoms disappear after 3 to 4 days. In others, some people do not experience any symptoms at all.

Toxic phase

A little percentage of patients who contract yellow fever (only 15 per cent) enter the toxic phase. Here, severe symptoms which include decreased urination, abdominal pains, vomiting (sometimes with blood), heart rhythm problems, seizures, delirium, bleeding from the mouth, nose, eyes or stomach, yellow discolouration of the eyes and skin.

This phase of the disease is fatal as half of the patients who enter the toxic phase die within 7–10 days.


Since there is no cure and the symptoms mimic those of other diseases, it makes it quite difficult to diagnose. This is why prevention (vaccination and mosquito control) is still the best approach.

The yellow fever vaccine is affordable and even free in certain states like Edo and Abuja. A single dose is all you need for life-long immunity against the disease.
