2.1 How the mosquito can transmit the pathogen?
The mosquitoes can transmit the pathogen to human or another mosquitoes in 3 ways. First is vertical transmissions. It mean pathogen from mother passed to their offspring via transovum and transovarial.Second is horizontal transmission. It occurs when female mosquitoes take a blood meal from viraemic host. The pathogen will developed inside the mosquito until complete extrinsic incubation and then bite new host, it can pass the pathogen to new host. After intrinsic incubation, host will become viraemic host and wait for new mosquito take a blood meal again. The last one is venereal transmission, this way has transmitted pathogen when mosquito mating directly from infected male mosquito to female mosquito.
2.2 What tool and how to determine the malaria transmission?
The tools can determine the malaria transmission are incidence rate ratio, entomological inoculation rate and vector capacity. For vector capacity can use vector surveillance to check by 6 determinants
1 Abundance : Numbers of mosquito
2 Host feeding patterns. : pattern of mosquito feeding on human or animal
3 Reproductive capacity. : how about mosquito reproductive system
4 Longevity. : mosquito old
5 Dispersal or distribution. : mosquito distribution on that time and place
6 Vector competence. : extrinsic incubation period of the pathogen in the vector
