![]() ![]() Sleeping sickness (African trypanosomiasis) Rickettsial diseases ( eg: spotted fever and Q fever)Ĭhagas disease (American trypanosomiasis) The list also illustrates the type of pathogen that causes the disease in humans. The following table is a non-exhaustive list of vector-borne disease, ordered according to the vector by which it is transmitted. Global travel and trade, unplanned urbanization, and en List of vector-borne diseases, according to their vector Other diseases such as Chikungunya, leishmaniasis and lymphatic filariasis cause chronic suffering, life-long morbidity, disability and occasional stigmatisation.ĭistribution of vector-borne diseases is determined by a complex set of demographic, environmental and social factors. Lives, and overwhelmed health systems in many countries. Since 2014, major outbreaks of dengue, malaria, chikungunya, yellow fever and Zika have afflicted populations, claimed The burden of these diseases is highest in tropical and subtropical areas, and they disproportionately affect the poorest populations. Every year there are more than 700,000 deaths from diseases such as malaria, dengue, schistosomiasis, human African trypanosomiasis, leishmaniasis,Ĭhagas disease, yellow fever, Japanese encephalitis and onchocerciasis. Vector-borne diseases are human illnesses caused by parasites, viruses and bacteria that are transmitted by vectors. Often, once a vector becomes infectious, they are capable of transmitting the pathogen for the rest of their life during each subsequent bite/blood meal. Or animal) and later transmit it into a new host, after the pathogen has replicated. Many of these vectors are bloodsucking insects, which ingest disease-producing microorganisms during a blood meal from an infected host (human Vectors are living organisms that can transmit infectious pathogens between humans, or from animals to humans. Many of vector-borne diseases are preventable, through protective measures, and community mobilisation.Other viral diseases transmitted by vectors include chikungunya fever, Zika virus fever, yellow fever, West Nile fever, Japanese encephalitis (all transmitted by mosquitoes), tick-borne encephalitis (transmitted by ticks).More than 3.9 billion people in over 129 countries are at risk of contracting dengue, with an estimated 96 million symptomatic cases and an estimated 40,000 deaths every year. Dengue is the most prevalent viral infection transmitted by Aedes mosquitoes.Most of the deaths occur in children under the age of 5 years. It causes an estimated 219 million cases globally, and results in more than 400,000 deaths every year. Malaria is a parasitic infection transmitted by Anopheline mosquitoes.They can be caused by either parasites, bacteria or viruses. Vector-borne diseases account for more than 17% of all infectious diseases, causing more than 700 000 deaths annually. ![]()
