Nearly half the world’s population lives in areas at risk of malaria transmission in 87 countries and territories (see attached map). In 2020, malaria caused an estimated 241 million clinical episodes, and 627,000 deaths. An estimated 95% of deaths in 2020 were in the WHO African Region. The predominant parasite species is <em>Plasmodium falciparum</em> , which is the species that is most likely to cause severe malaria and death. Where malaria is found depends mainly on climatic factors such as temperature, humidity, and rainfall. Malaria is transmitted in tropical and subtropical areas, where <em>Anopheles</em> mosquitoes can survive and multiply, and malaria parasites can complete their growth cycle in the mosquitoes (“extrinsic incubation period”). Temperature is particularly critical. For example, at temperatures below 20°C (68°F), <em>Plasmodium falciparum</em> (which causes severe malaria) cannot complete its growth cycle in the <em>Anopheles</em> mosquito, and thus cannot be transmitted.<br><strong>African Trypanosomiasis</strong> - also known as “sleeping sickness”, is caused by microscopic parasites of the species <em>Trypanosoma brucei</em>. It is transmitted by the tsetse fly (<em>Glossina</em> species), which is found only in sub-Saharan Africa. Two morphologically indistinguishable subspecies of the parasite cause distinct disease patterns in humans: <em>T. b. gambiense</em> causes a slowly progressing African trypanosomiasis in western and central Africa and <em>T. b. rhodesiense</em> causes a more acute African trypanosomiasis in eastern and southern Africa. Control efforts have reduced the number of annual cases and for the first time in 50 years, the number of reported cases fell under 10,000 in 2009. In 2017–2018, fewer than 2000 cases were reported to WHO. The number of cases continue to drop and in 2020, fewer than 700 combined cases were reported to WHO; over 85% caused by <em>T. b. gambiense</em> and around 15% caused by <em>T. b. rhodesiense</em>.

Almost half of the world’s population, about 4 billion people, live in areas with a risk of dengue. Dengue is often a leading cause of illness in areas with risk. Each year, up to 400 million people get infected with dengue. Approximately 100 million people get sick from infection, and 40,000 die from severe dengue. Dengue has emerged as a worldwide problem since the 1960s. The disease is common in many popular tourist destinations in the Caribbean (including Puerto Rico), Central and South America, Southeast Asia, and the Pacific Islands (see attached regional maps). In the United States, local cases and limited spread of dengue does occur periodically in some states with hot, humid climates and <em>Aedes</em> mosquitoes."
