1.The virus is inoculatedinto humans with themosquito saliva.

2.The virus localizes andreplicates in varioustarget organs forexample local lymphnodes and the liver.

!.The virus is thenreleased from thesetissues and spreadsthrough the blood toinfect white blood cellsand other lymphatic

tissues.

".The virus is thenreleased from thesetissues and circulates inthe blood.

#.The mosquito ingests blood containing the virus.

$.The virus replicates in the mosquito midgut theovaries nerve tissue and fat body. It then escapesinto the body cavity and later infects the salivaryglands.

%.The virus replicates in the salivary glands andwhen the mosquito bites another human the cyclecontinues.
