World Health Day 2014: Small Bites, Big Threats


Vector-borne diseases are infectious diseases spread by intermediate organisms, such as insects and snails that transmit viruses, parasites, and bacteria to humans. These diseases cause a high burden of illness and death for individuals, their families, and communities, especially in poorer countries; they lead to school absenteeism, worsening of poverty, a negative impact on the economic productivity, high health costs and overloaded health systems in countries. Vector-borne diseases exercising significant impact in the Americas are mainly malaria, dengue, Chagas disease, leishmaniasis, lymphatic filariasis, schistosomiasis, and trachoma. Vector-borne diseases is the theme for World Health Day 2014 which is celebrated every 7th of April.
