The parasite is a part and prime focus of the disease, then sets in the red blood cells and damages the entire human body (Webb 281).

Plasmodium is a parasite with over 100 species, but only four directly affect humans(“Malaria Parasites”). This parasite affects the circulatory system, or cardiovascular system. It’s structured of many things, and some structures are in common with animals or human cells. Even though it’s microscopic in size, it can cause a lot of damage. The parasite gets into the body from mosquitoes and infects the bloodstream of the circulatory system. Plasmodium affects the cardiovascular system. The cardiovascular

Pesticides are available in different types of formulations to target the mosquitoes. Mosquito coil (Megha Pant et al., 2016), a burning fumigant is one of them, but generated smoke is the matter of concern (Weili Liu et al., 2003) on the other hand mosquito repellent creams are associated with problems of allergy or develops rashes (Bhupen Katalia et al., 2013) and the effect is for a limited time in both methods.

Originating from Latin America, American Trypanosomiasis, or better known as Chagas Disease, is a “systematic chronic parasitic infection by Trypanosoma cruzi” (Ramos, et al. 919). It was discovered in 1909 by a Brazilian researcher named Carlos Ribeiro Justiniano Chagas, which was where the disease obtained its name from. Chagas Disease has expanded from Latin America to other countries, including Mexico. Rural areas are at great risk of this of developing this disease, but migration has been a

Nature & History of the disease Chagas disease, also known as American Trypanosomiasis, is a tropical disease caused by the parasite Trypanosoma cruzi, transmitted to humans through contact with the feces of an infected triatomine bug. The triatomine bug known as the kissing bug is a subspecies of the Reduviidae family. The bug itself does not cause the disease. Through contact with the fecal matter from the kissing bug, which is excreted near the bite wound, the parasite enters the bloodstream
