The requirement is a 2500 word essay, fully referenced with at least 5 references. use all resources to get to know your parasite or parasite-related topic. Starting with Wikipedia and the CDC for a rough understanding then turn to the refs sent to you. The Wikipedia and CDC searches must not be quoted, if needed quote their references and only if you have read them. Google the ref titles I sent for their NCBI listing to find out who has referenced that work to see how the research is moving forward in the field of your topic.
