Vector-borne diseases

Vector-borne diseases are illnesses caused by pathogens and parasites in human populations. Every year there are more than 1 billion cases and over 1 million deaths from vector-borne diseases such as malaria, dengue, schistosomiasis, human African trypanosomiasis, leishmaniasis, Chagas disease, yellow fever, Japanese encephalitis and onchocerciasis, globally.

Vector-borne diseases account for over 17% of all infectious diseases.

病媒传播的疾病

病媒传播的疾病是由人群中的病原体和寄生虫引起的疾病。每年疟疾、登革热、血吸虫病、非洲人类锥虫病、利什曼病、恰加斯病、黄热病、日本脑炎和盘尾丝虫病在全世界导致10亿多起病例和超过100万人死亡。

病媒传播的疾病占所有传染病的17%以上。

Key facts

Main vectors and diseases they transmit

主要病媒及其所传播的疾病

Vectors are living organisms that can transmit infectious diseases between humans or from animals to humans. Many of these vectors are bloodsucking insects, which ingest disease-producing microorganisms during a blood meal from an infected host (human or animal) and later inject it into a new host during their subsequent blood meal.

Mosquitoes are the best known disease vector. Others include ticks, flies, sandflies, fleas, triatomine bugs and some freshwater aquatic snails.

病媒是指能够在人和人之间或者从动物到人传播传染病的生物体。许多病媒是吸血昆虫，在从被感染宿主（人或动物）身上吸食血液时摄入产生疾病的微生物，然后在随后吸食血液的过程中将其注入新宿主体内。

蚊子是最为人所知的病媒。其它病媒还包括蜱、蝇、沙蝇、跳蚤、锥蝽和一些淡水螺。
