World Heath Day also raises awareness about a public health issue. This year's World Health Day theme is "Small Bite, Big Threat" regarding vector-borne diseases. According to the WHO, "vectors are organisms that transmit pathogens and parasites from one infected person (or animal) to another." They are commonly found in tropical areas and in areas without safe drinking water and sanitation and are spread by mosquitoes, ticks, bugs, freshwater snails and flies.

Over 1 million people die each year from vector-borne diseases including malaria, dengue, lyme disease, yellow fever and Chagas disease, to name a few. It is estimated that over 600,000 people died in 2012 from malaria, the most deadly vector-borne disease. Nearly half of the world's population is at risk from dengue, a mosquito-borne viral infection that can also be fatal.
