Document Summary
The benefit of replicating within a host means that you can transmit. The more you replicate in the host, the more damage you do to the host. The cost of direct transmission on the host are higher. The optimal replication rate for a direct transmission disease is lower. X axis is density within the host, y axis is the amount that can be transmitted into the mosquito, y axis is how many transition stages the malaria is making. As age increases, the effects of malaria are getting lower. Theres a positive relationship between in host replication and between host transmission. Theres also a positive relationship between in host replication and mortality rate. The entomological infection rate is the amount of infectious bites per year, ad in some parts of the world there are 300 bites/year and the mosquitos can have different malaria genotypes.
