Nigeria’s Federal Ministry of Health has confirmed one case of Yellow Fever in the Ifelodun Local Government Area of Kwara State.
According to the WHO, Yellow fever is an acute viral haemorrhagic disease transmitted by infected #mosquitoes.
Symptoms of yellow fever include fever, headache, jaundice, muscle pain, nausea, vomiting and fatigue. The “yellow” in the name refers to the jaundice that affects some patients.
Yellow fever is prevented by an extremely effective vaccine, which is #safe and affordable. A single #dose of yellow fever vaccine is sufficient to confer sustained immunity and life-long protection against yellow fever disease and a booster dose of the #vaccine is not needed.
The vaccine provides effective immunity within 30 days for 99% of persons vaccinated.
Good supportive treatment in hospitals improves survival rates. There is currently no specific anti-viral drug for yellow fever.
A small percentage of patients, however, enter a second, more #toxic phase within 24 hours of recovering from initial symptoms.
High fever returns and several body systems are affected, usually the liver and the kidneys. In this phase people are likely to develop jaundice (yellowing of the skin and eyes, hence the name ‘yellow fever’), dark urine and abdominal pain with vomiting.
Bleeding can occur from the mouth, nose, eyes or stomach. Half of the patients who enter the toxic phase die within 7 – 10 days.
