For World Health Day 2014, a special film was commissioned to highlight the challenges posed by a number of vector-borne diseases in the Western Pacific Region, along with stories from the frontlines depicting how WHO supports Member States in tackling these diseases. In "Small Bite, Big Threat", filmmaker Mark Hammond captures several stories showing how collaboration between governments and civil society, supported by WHO, is vital in addressing malaria, dengue, schistosomiasis, lymphatic filariasis and Japanese encephalitis.

Mosquitoes, ticks, sandflies, freshwater snails. Malaria, dengue, leishmaniasis, schistosomiasis. Just a few of the many vectors and the diseases they spread globally, including throughout the Western Pacific Region. “Small bite, big threat” is the theme of this year’s World Health Day — celebrated on 7 April to mark the anniversary of WHO’s founding in 1948. Each year a theme is selected that highlights a priority area of public health concern in the world.
