Japanese Encephalitis Virus

Hi, I'm Japanese Encephalitis Virus.
I'm from Flaviviridae and an arborvirus.
I'm big all over Asia.

I live around rice fields.

I hang around pigs and water birds there.

Mosquitoes are my vectors.
That means they carry me from the animals to you.

My main job is giving you encephalitis.

I can have life long consequences.

There is a vaccine against me.

Dengue Virus

We're the Dengue Virus!
We're Flaviviruses.

We're found in the tropics.

We hitch a ride on an Aedes mosquito.
When she bites you, we get left behind.

We are 4 types.
A visit from one of us makes you sick with Dengue fever.
But we 'cross react' with each other.

So when another one of us visits, you get very sick.

You get Dengue haemorrhagic fever and can die.

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.
