World Health Day

World Health Day 2014 Vector-borne diseases

Vectors, such as mosquitoes, fleas, and ticks transmit parasites, viruses or bacteria between people or between animals and people. Vector-borne diseases account for 17% of the estimated global burden of all infectious diseases; they have the biggest impact on the world’s poorest people.  Everyone, rich and poor, in all corners of the world are at risk for infections. Global trade, rapid international travel, and environmental changes, such as climate change and urbanization, are causing vectors and vector-borne diseases to spread beyond borders.  
Increased action by the global community is needed urgently to address vector-borne diseases.
