The reason that why malaria, leishmaniasis, and trypanosomiasis are primarily diseases of tropical regions and how could humans be affecting the future geographical ranges of these diseases. Concept introduction: Malaria is a disease caused by Plasmodium which is parasitic protozoan and is transmitted to humans by infected female Anopheles mosquitoes. Genus Trypanosoma is the globally significant member of Euglenozoa as they exist only in parasitic forms. They cause sleeping sickness and Chagas disease which is transmitted to humans through kissing bugs. Other parasitic Euglenozoa belong to genus Leishmania which is a member of trypanosomes. The members of Leishmania are responsible for causing leishmaniasis which is transmitted to humans by the sandfly.

Question

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.

Explain why the diseases malaria, leishmaniasis, andtrypanosomiasis are primarily diseases of tropical regions.

Explain how each of the following could lead to the reemergence of malaria in the United States: (a) global warming, (b) increased travel of individuals from endemic regions to the United States, (c) increased immigration of individuals from endemic regions to the United States, and (d) laws protecting wetlands. Please simple to understand and original answer. Thanks :)

Even though genetically engineered mosquitoes might be developed that do not allow the reproduction of malaria protozoa, these mosquitoes would have little, if any, immediate effect on the spread of the disease. Why should this be so? What would have to happen for these mosquitoes to significantly affect the spread of malaria?
