What are Vector-borne diseases?

Vector-borne diseases are highly dangerous afflictions which can be transmitted to humans and animals through other living organisms, such as mosquitoes, fleas, flies or ticks. Most of them can cause death or even secondary effects such as blindness or weakness, and although for a long time it was believed that this illnesses had disappeared from highly developed countries, the reality is that they’ve been reappearing and increasing as a consequence of climate change and frequent travels from one country to another due to commerce or recreation.

Some of the most common and dangerous vector-borne diseases are: malaria, yellow fever, chagas disease, dengue, etc. They appear in urban or rural environments, since these places have plenty of potential hosts: from animals to humans. Most of the vectors are also attracted by the ecological conditions of these places, in which garbage, puddles of dirty water, heat, etc. are abundant.
