The bugs are getting worse
Climate change and shifting environmental patterns are contributing to the increased prevalence and geographic spread of disease-carrying insects like ticks and flies. Experts warn that these pests are becoming a greater public health threat as they move into new regions.
Why it matters
The expansion of vector-borne diseases poses a growing challenge to public health systems and requires increased monitoring and adaptation strategies.
It’s not difficult to accidentally learn too much about bugs. Unfortunately, though, we have to, because they’re spreading out, inventing new ways to torture us and just generally making life less pleasant. Take houseflies: They thrive in warmer temperatures, and it turns out they’re not just annoying; they can also be what bug nerds call mechanical vectors of disease. Put simply, it means they walk through garbage and then around your countertops, leaving salmonella and untold other pathogens along with their tiny fly footprints. Or how about longhorned ticks? They first popped up on American shores in 2017 — and they can clone themselves. Female ticks just make thousands of self-Xeroxes; on the extremely rare occasions males are produced, it’s thought to be by mistake. Unsurprisingly, they’re a growing concern for the US, too.
