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.
