Vector Borne Diseases Quotes

Recognizing its importance, Aedes aegypti should be studied as a long-term national, regional, and world problem rather than as a temporary local threat to the communities suffering at any given moment from yellow fever, dengue or other aegypti-borne disease. No one can foresee the extent of the future threat of Aedes aegypti to mankind as a vector of known virus diseases, and none can foretell what other virus diseases may yet affect regions where A. aegypti is permitted to remain.

The research is still in its infancy, as we have seen, but, in early March 2020, Nature Communications published a model study that followed the link all the way from shelf to sickbed in one case: malaria, one of those beneath-the-radar diseases, affecting some 230 million and killing 400,000 per year, the vast majority in rainforest biomes. Deforestation is a boost for the mosquito vectors. More sunlight reaches the soil where the larvae develop; when biodiversity retreats, fewer animals prey on them. Nigeria suffers most from malaria due to deforestation. It is largely caused by the export of timber and cocoa. Such commodities end up in the north: consumers with the greatest malaria footprint are the cocoa-guzzling Dutch and Belgians, Swiss and Germans. 'In this unequal value chain, ecosystem degradation and malaria risk are borne by low-income producers' - or, in plainer terms: the Europeans get the chocolate and the profits, the Africans the mosquitos.

Few diseases have had an impact on human evolution, culture and society on par with malaria. It is one of the oldest documented infectious diseases. Indeed, it has been hypothesised that the protective effect bestowed by a heterozygous sickle cell allele explains its survival to the modern day. As such, malaria has left its footprint on human evolution in a profound way few other diseases have. Yet its true origins were the matter of considerable controversy. The clue is in the name – the prevailing theory until Ross's discovery was that malaria resulted from 'mala aria', that is, 'bad air'. It took the advent of modern evidence-based medical science to challenge this 'miasma theory'. Ross's elucidation of the role of mosquitoes in the lifecycle of malaria has opened up a new subject for epidemiological consideration: the vector-borne disease.

Akeyla was probably correct— werewolves rarely caught colds. But then again, Jax was a third grader, and kids were known disease vectors. “Nice of you to bring him his studies,
