A research team including a Keele scientist has found that countries with higher levels of air pollution were also more likely to have higher numbers of deaths from dengue, a rapidly expanding disease spread by mosquitoes. The team, including Keele’s Dr. Najmul Haider, conducted a multi-country study across 20 nations across Asia, Africa and Latin America where dengue is endemic, and found that those with higher levels of air pollution also had higher numbers of dengue-related deaths during that time.
