1. How the mosquito can transmit the pathogen?
The transmission of pathogen by mosquito can occur 3 pathways based on mosquito life cycle. The first one is Vertical Transmission (Egg laying). If it has pathogen can transfer from mother to its children.
The Second, Venereal Transmission is pathogen can transmitted from one to another one by sexual transmissions (it can called matting in life cycle). So, both male and female mosquitoes can be infected.
The Third, Horizontal Transmission is pathogen can pass to another host by mosquito bites. Host is may be human or animals. After infection mosquito bites, pathogen will develop to suitable stage for wait new mosquito take a blood again and infected in new mosquito.
2. What tool and how to determine the malaria transmission?
The tools use to determine the malaria transmission are Vectorial Capacity. It describe relationships between vectors and hosts have 6 main determinants. Such as,
– Abundance : the information of mosquito numbers and case malaria infection in different seasons, different areas.
– Host preference and host-feeding patterns and proportion : The mosquito favor sugar feeding and take a blood from human or animals.
– Reproductive capacity : rate of population of mosquito.
– Dispersal or distribution : the number of case malaria infection.
– Vector competence : ability of mosquito transfer pathogen to other host or vector.
