Vector-borne disease control is heavily influenced by environmental control of vectors such as mosquitos and flies that carry bacteria, viruses or parasites causing various diarrhoeal, skin and eye diseases. The WHO estimates that vector-borne diseases, such as dengue, malaria, Lyme disease and typhus, account for 17% all infectious diseases. The burden of these diseases is heaviest among under-privileged rural populations in tropical and subtropical countries. Climate change and patterns of urban development such as slums where the management of solid waste and foul water is poor aggravate health risks of people living in vulnerability.
Many of the vector borne diseases are preventable. GX is developing vector-borne disease control programmes in partnership with local health centres and in areas of its Cataract intervention programs to bring maximum co-benefits to the communities which it aims to serve.
