Vector-Borne Diseases


Vector-borne diseases are diseases that spread to people and animals primarily through the bite of an infected mosquito, tick, or flea. VBDs can be classified into 4 major groups: Arthropod-Borne Viruses (Arboviral diseases: chikungunya, West Nile, yellow fever, dengue, and Zika), Bacterial Vector-Borne Diseases (Plague, lyme disease and tularemia), Rickettsial zoonotic diseases (Q fever, Rocky Mountain spotted fever, and typhus fever), and parasitic VBDs (malaria, leishmaniasis, and trypansomiasis). As per the WHO, VBDs account for more than 17% of all infectious diseases, causing more than 700, 000 deaths annually. The distribution of vector-borne diseases is determined by complex demographic, environmental, and social factors. The burden of these diseases is highest in tropical and subtropical areas and they disproportionately affect the poorest populations. Recently, major outbreaks of dengue, malaria, chikungunya, yellow fever, and Zika occurred. Many of these diseases are preventable through informed protective measures.
