Katherine Bliss, senior associate at the Global Health Policy Center of the Center for Strategic and International Studies (CSIS), writes in the center’s “Smart Global Health” blog about this year’s World Health Day, the theme of which was “preventing vector-borne diseases.” She writes, “With more than one billion people globally infected by vector-borne diseases each year, and with one million deaths occurring annually as a result, this year’s World Health Day message is that strengthening prevention activities and protecting the most vulnerable social sectors from vector-borne diseases are essential. Through international, regional, and local level cooperation in managing educational campaigns and vector-management activities, community members and public officials can work hand in hand to take a bite out of vector-borne diseases” (4/10).
