“Dengue has become a global problem since the Second World War and is common in more than 120 countries, mainly in Southeast Asia, South Asia and South America. About 390 million people are infected per year, about half a million require hospital admission, and approximately 40,000 die. In 2019, a significant increase in the number of cases was seen. Apart from eliminating the mosquitos, work is ongoing for medication targeted directly at the virus. It is classified as a neglected **tropical** disease.”
Not a common Arizona desert disease.
