This includes diseases such as cholera, from fecal contaminated water. Cholera is transmitted by which of the following routes? Ovector transmission vehicle transmission droplet transmission contact transmissionAssuming you have been posted to a community where malaria is very endemic. There is a high rate of absenteeism among your students due to incidents of malaria. As part of your community engagement explain how you would educate on malaria prevention taking the following into consideration:a) Name of the vector and the species of the parasite that cause the diseases in Africa; b) Two chemical and two biological ways of reducing the population of mosquitoes; c) Two in-house measures to prevent mosquitoes bite;d) The stages in the life cycle of the mosquito;e) The names of three African countries that participated in the trial of malarial vaccine.

Relating to the host-pathogen relationship, explain how they had different outcomes.
