The Nigeria Centre for Disease Control (NCDC) has reported a total of 1,179 suspected cases of yellow fever from 416 local government areas in 36 states of the federation and the Federal Capital Territory.
The cases were reported between January 1, 2022, and July 31, 2022.
According to the situation report obtained by our correspondent, a total of 14 deaths have been recorded from suspected cases in 10 of the states.
Yellow fever is an acute viral haemorrhagic disease transmitted by infected mosquitoes. The ‘yellow’ in the name refers to jaundice that affects some patients.
Symptoms of yellow fever include fever, headache, jaundice, muscle pain, nausea, vomiting and fatigue. A small proportion of patients, who contract the virus, develop severe symptoms and approximately half of them die within seven and 10 days.
The NCDC said 74 per cent of cases were people predominantly aged 30 years and below.
