How Climate Change Influences the Path of Malaria-Carrying Mosquitoes
Malaria predictions serve an obvious purpose, but they don't always tell you how susceptible a particular town or village might be.
In fact, a group of professors and researchers found that the likelihood of malaria-carrying mosquitoes showing up in particularly can vary more than most would imagine.
"People might have an interest in predictions for global malaria trends and even more so for regional patterns, but they probably care most about what's going to happen in their own town or village," said Matthew Thomas, a Penn State University professor and Huck Scholar in ecological entomology. "What is likely to happen in one location can be very different from another location just 50 miles down the road."
Thomas and others from Penn State, the Barcelona Centre for International Health Research and the universities of Pennsylvania and Massachusetts found that climate change strongly influences the ability of mosquitoes to transmit malaria and where they might travel.

"Malaria mosquitoes are ectothermic organisms, which means that their body temperature matches the temperature of their direct surroundings," said Krijn Paaijmans, an assistant research professor at the Barcelona Centre for International Health Research.
"Fine-scale predictions of malaria risk will be better tailored to the needs of local communities and can improve local adaptation and mitigation strategies."
The research team set out to examine the malaria risk for four locations. They researchers used a mathematical model that incorporates the influence of temperature on adult mosquitoes' transmission of malaria parasites and compares it to the predictions they obtained in the four locations with predictions from coarse-scale model simulations. The result was over- and underestimation of climate change impacts.
"This is one of the first studies to attempt to explore how climate change might impact conditions at the local level," said Dr. Michael E. Mann, a distinguished professor of meteorology at Penn State.
"The results suggest the possibility that population centers in cool highland regions could be more vulnerable than previously thought, while other equally large lowland areas might be less vulnerable. But this would have to be confirmed with more detailed modeling assessments that take into account the full suite of environmental and socio-economic factors that ultimately determine risk of malaria."

The connection between the pandemic and our dietary habits is undeniable. The stress of isolation coupled with a struggling economy has caused many of us to seek comfort with our old friends: Big Mac, Tom Collins, Ben and Jerry. But overindulging in this kind of food and drink might not just be affecting your waistline, but could potentially put you at greater risk of illness by hindering your immune system.

As the world continues to navigate the line between reopening and maintaining safety protocols to slow the spread of the coronavirus, rapid and accurate diagnostic screening remains critical to control the outbreak. New mobile-phone-based, self-administered COVID-19 tests being developed independently around the world could be a key breakthrough in making testing more widely available, especially in developing nations.
