We strengthen the capacity to prevent and respond to emerging vector-borne diseases in the Southwestern U.S. and Pacific Islands.

The Pacific Southwest is a region with diverse ecological landscapes, ranging from cool temperate forests to dry, hot deserts, making the region highly susceptible to invasive vectors, exotic pathogens such as Zika virus, and several endemic pathogens transmitted by mosquitoes and ticks. Our center involves a diverse group of professionals, ranging from researchers to public health experts, to address these public health challenges.


Subscribe to our weekly newsletters for vector-borne disease news, new career and training opportunities, important announcements, and research updates.


View publications by PacVec students, trainees, and investigators.


Learn about the tick species that pose health risks for both humans and animals in the region and view public health information on ticks.


The BiTeRS program offers services to enhance surveillance for ticks and tick-borne pathogens of human health concern in California and Arizona.

The Pacific Southwest Regional Center of Excellence in Vector-Borne Diseases is supported through Cooperative Agreement Number 1U01CK000649 between the Centers for Disease Control and Prevention (CDC) and the University of California, Davis.
