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.
2015–16 Zika virus epidemic
Zika is a mosquito-borne disease. The resurgence of "Aedes aegypti"s worldwide distribution over the past 2–3 decades makes it one of the most widely distributed mosquito species. In 2015, "Aedes albopictus" was present in tropical, subtropical, and temperate regions of the Americas, reaching as far north as the Great Lakes of North America and, internationally, living alongside "Aedes aegypti" in some tropical and subtropical regions.
