Malaria is a life-threatening disease that continues to impact millions worldwide. Researchers at @uofuhealth.bsky.social are working from multiple angles to better understand, prevent, and treat it. Learn more about their work. bit.ly/4txuBGE
This infographic provides information about malaria. It highlights that half of the world's population is at risk, malaria is caused by Plasmodium parasites, and climate change impacts mosquito survival. In 2025, there were 282 million cases worldwide. The infographic also presents researchers like Tracey Lamb, Ellen Leffler, and Paul Sigala discussing vaccine development, genetic variations, and new medicines to combat malaria. An image of a mosquito is included in the design.
