The Importance of World Dengue Day

Mosquito-borne Diseases & the Environment

Climate change and human activity are enabling the spread of mosquito-borne diseases, like dengue fever, to new places. Stanford infectious disease experts and disease ecologists discuss what we know and how communities can protect themselves from these changing disease threats.

Aedes aegypti: Beyond the Black and White

One look at Aedes aegypti gives an immediate impression of its menacing nature. The telltale dark and white bands on the mosquito’s legs and other body parts bring a sense of foreboding and hardship. Sleek, silent, and stealthy, Ae. aegypti is the primary vector for several important, debilitating, and sometimes fatal human diseases including dengue, Zika virus, yellow fever, and chikungunya. The species is cause for mounting concern on many levels, as its biology, behavior, and ability to adapt have made Aedes aegypti one of the most pervasive and daunting public health challenges in the modern world.

The first mosquito ever associated with the spread of disease, Ae. aegypti is also the most studied of all mosquito species.1 From its humble beginnings in the African wild to a footprint that spans the globe, this durable and opportunistic insect has become a formidable opponent of vector control efforts worldwide.

Power of Water: Mexico’s Water Warriors

High in the hills of the San Juan Tlacotenco Forest, the worth of water is revealed as nearby villagers make the arduous journey to the Zacasonapan Spring.

For generations, the pilgrimage has been a regular tradition for many who live in the area and rely on the natural water source for survival. A particularly steep and rocky path shows just how treacherous it can be, especially while hauling heavy water jugs on the way back home.

Clean Water: A Basic Need for Health and Survival

Clean water is essential for all life on Earth to thrive. The water cycle is not contained within our countries’ borders or boundaries, which makes it a challenge to monitor, maintain and implement improvements and changes. Ownership of, and access to, this essential natural resource has been at the forefront of many disputes around the world, between neighboring countries and communities, and even countries on opposite sides of an ocean. Across the globe we are observing conflicts, wars and water refugees as people struggle for equal access to what has been widely termed as Blue Gold.

Economies on both a national and local level depend upon clean freshwater and saltwater regions. In theory, a thriving economy has the ability to fund infrastructure projects and provide basic needs for all of its citizens. However, even wealthy countries are struggling to provide sufficient standards of clean water, with each region negotiating its own bespoke complications.

Trillion Trees: Communities Working to Restore Forests
