Plasmodium vivax
Plasmodium vivax is a protozoal parasite and a human pathogen. This parasite is the most frequent and widely distributed cause of recurring (Benign tertian) malaria, "P. vivax" is one of the five species of malaria parasites that commonly infect humans. Although it is less virulent than "Plasmodium falciparum", the deadliest of the five human malaria parasites, "P. vivax" malaria infections can lead to severe disease and death, often due to splenomegaly (a pathologically enlarged spleen). "P. vivax" is carried by the female "Anopheles" mosquito; the males do not bite.
Mosquito-borne disease
From the success seen in Australia, the researchers were able to begin operating in more threatened portions of the world. The Eliminate Dengue program spread to 10 countries throughout Asia, Latin America, and the Western Pacific blooming into the non-profit organization, World Mosquito Program, as of September 2017. They still use the same technique of infecting wild populations of "Ae. aegypti" as they did in Australia, but this time their target disease has shifted to include Zika and chikungunya on top of dengue. Although not alone in their efforts to use "Wolbachia-"infected mosquitoes to reduce mosquito-borne disease, the World Mosquito Program method is praised for being self-sustaining in that it causes permanent phenotype change rather than reducing mosquito populations through cytoplasmic incompatibility through male-only dispersal.
