Plasmodium falciparum
Plasmodium falciparum is a unicellular protozoan parasite of humans, and the deadliest species of "Plasmodium" that cause malaria in humans. It is transmitted through the bite of a female "Anopheles" mosquito. It is responsible for roughly 50% of all malaria cases. It causes the disease's most dangerous form called falciparum malaria. It is therefore regarded as the deadliest parasite in humans, causing 435,000 deaths in 2017. It is also associated with the development of blood cancer (Burkitt's lymphoma) and is classified as Group 2A carcinogen.
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.
