Viral comments (21): Dengue virus, another pathogen, now globalized, which knocks at our door

There are a number of vector-borne diseases, those that are by arthropod vectors such as mosquitoes and ticks, which are becoming more likely in our regions as a result of globalization (especially in what it has to facilitate the movement of goods and people), and disturbances caused by climate change.
