The transmission patterns is a pattern of vector transmitted the pathogen to another vector for spread the disease to another host. This mechanism can divide into 3 ways. First is Vertical transmission that the mosquitoes transmit the pathogen to their offspring via egg, it call transovum (virus on egg surface) and transovarial (virus in embryos). Second is Horizontal transmission, it’s mechanical of mosquitoes transmitted the pathogen to another mosquitoes via biting. When mosquitoes take a blood meal form infected host, they will get the pathogen form host and pathogen growth to ready to infect new host. The mosquitoes take a blood meal again and release the pathogen to uninflected hosts until the pathogen ready to infect mosquitoes. Uninflected mosquitoes will come and take a blood meal on this host can get the pathogen form host. And the last one is about mechanisms of vector to transmit the pathogen between adults mosquitoes via mating process can call Venereal transmission.
