Malaria is caused by a protozoan of the genus Plasmodium and transmitted to humans by Anopheles mosquito. Population at risk of malaria live in tropical vulnerable areas, where they are exposed to the mosquitoes carrying the protozoan. Early symptoms of malaria are similar to those of the common flu: headache and joint pain, fever, etc. When the disease reaches advanced stages, it causes anaemia, liver problems and even death.
At this time, Ecuador is in the pre-elimination of malaria stage, according to the annual report of the World Health Organization [WHO]. Reduce the population of mosquitoes that transmit the disease and the exposure of humans to infected mosquitoes are the main strategies to eliminate malaria.
In this projects, we propose to design and simulate optimal control problems of the SEIR (Susceptible-Exposed-Infected-Removed) equations for the two populations of interest: humans and mosquitoes. The control variables will represent strategies such as fumigation and the use of ITNs (insecticide treated nets). These strategies follow the WHO recommendations.
