providing training (capacity building) on clinical management, diagnosis and vector control with support from some of its collaborating centres and.supporting countries to improve their reporting systems and capture the true burden of the disease.
Specifically WHO responds to vector-borne diseases by: WHO Secretariat provides strategic, normative and technical guidance to countries and development partners for strengthening vector control as a fundamental approach based on GVCR to preventing disease and responding to outbreaks.
Ultimately, this will support implementation of a comprehensive approach to vector control that will enable the achievement of disease-specific national and global goals and contribute to achievement of the Sustainable Development Goals and Universal Health Coverage. To achieve this a re-alignment of vector control programmes is required, supported by increased technical capacity, improved infrastructure, strengthened monitoring and surveillance systems, and greater community mobilization. It provides strategic guidance to countries and development partners for urgent strengthening of vector control as a fundamental approach to preventing disease and responding to outbreaks. The " Global Vector Control Response (GVCR) 2017–2030" was approved by the World Health Assembly in 2017. 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.
Vector-borne diseases account for more than 17% of all infectious diseases, causing more than 700 000 deaths annually.
