Some things change over time. Others don’t.
For thousands of years, tiny creatures like mosquitoes, midges, and ticks have had a huge impact on human and creature well-being, disrupting—and often ending—life.
Knowledge is power, and it’s time we used ours to implement solutions to this ongoing, ancient, but very real threat.

What is a Vector-Borne Disease?
Still Here
You thought they were history. They’re not. Mosquitoes, ticks, and fleas still carry diseases that affect people every year.
What’s a Vector?
A vector is a bug that carries germs—viruses, parasites, bacteria. When it bites, it can make people or animals sick.
What is a Vector-Borne Disease?
When a bug bite leads to illness, it’s a vector-borne disease (VBD). Think West Nile, Lyme, dengue—even new threats like Oropouche.
Why It Matters
Climate change, global travel, and growing bug populations are making these diseases more common—even close to home.
The Good News
We know how to stop them. Learn about the bugs, the diseases they spread, and how to protect your family.

Why They Still Matter Today
These aren’t relics of the past. West Nile and Lyme cases are rising in the U.S., dengue is expanding, and new diseases like Oropouche are spreading into new regions. The threats are evolving, but so are the solutions.
A New (and Old) Threat
Oropouche
This little-known virus is spreading across South and Central America—and travelers have brought it back to the U.S. Learn what it is, how it spreads, and how to protect yourself.
