Dengue

Alessandra Della Torre, professor at Sapienza University:«With climate change the life cycle of larvae is shortened»

Aedes aegypti mosquitoes, one of the most common species in the U.S., love everything about humans. They love our body heat and odors, which enable them to find us. They love to feed on our blood to make their eggs mature. They even love all the standing water that we create. Uncovered containers, old tires and junk piles collect water and are perfect for breeding. And with the advent of warm weather across the southern U.S., mosquito breeding season is already underway. Given all the options that Aedes females have in urban areas, how do these cosmopolitan mosquitoes find the perfect site to lay their eggs? Scientists previously thought this was a solitary act, but now research shows that female Aedes aegypti mosquitoes – the main vector in the U.S. for diseases such as Zika, dengue, chikungunya and other viruses – can rely on one another for good reviews of breeding sites. Our Laboratory of Tropical Genetics at Florida International University discovered a new b...

The European Center for Disease Control speaks of the risk linked to the rain and heat of these weeks

Leer in español There are questions that worry me profoundly as a population- and environmental-health scientist. Will we have enough food for a growing global population? How will we take care of more people in the next pandemic? What will heat do to millions with hypertension? Will countries wage water wars because of increasing droughts? These risks all have three things in common: health, climate change and a growing population that the United Nations determined passed 8 billion people in November 2022 – double the population of just 48 years ago. In my 40-year career, first working in the Amazon rainforest and the Centers for Disease Control and Prevention, and then in academia, I have encountered many public health threats, but none so intransigent and pervasive as climate change. Of the multitude of climate-related adverse health effects, the following four represent the greatest public health concerns for a growing population. Infectious disease...
