Yellow Fever Virus
Hey, I'm Yellow Fever Virus.
I am from family Flaviviridae.
I am in Africa and South America.
I am an arborvirus.
This means I am carried in mosquitoes and ticks.
I travel in their saliva.
Like many of my arborvirus friends, I give you fever and haemorrhage.
Then headache and chills.
I make you yellow with jaundice.
I have two different homes to grow in.
My urban life cycle hangs around houses.
My sylvatic cycle uses monkeys in the jungle.
Oh well, there is a vaccine against me.
