Spread by Mosquitoes, Ticks, and Fleas

Infectious diseases can be found everywhere, and NCEZID is engaged in preventing, tracking, detecting, and responding to outbreaks of infectious disease throughout the United States and the world. The links below reference stories and updates about our work from 2011 to the present to protect people from the threat of vector-borne infections spread by mosquitoes, ticks, and fleas. Chikungunya and dengue are vector-borne diseases.
