EMERGING PATHOGENS

As climate and environment changes, humans, plants and animals increasingly migrate, allowing disease-causing organisms of all kinds to find new areas and new hosts to live in. This leads to frequent emergence of new diseases. Such effects can be intensified by socio-economic processes, such as population growth, human migration, urbanization, global trade, tourism that act on shorter timeframes, and have a feedback loop on the environment. This is the emerging infectious disease crisis representing an existential threat to all of humanity; technological, heavily urbanized humanity may be at particular risk. Because we cannot stop or reverse this phenomenon, it is essential to prepare for its consequences and to design a proactive strategy. Continue ››


Mosquitoes

Mosquitoes are the most important vector organisms that affect both human and animal health because of their roles in spreading pathogens. They are responsible for about a million human deaths annually and worldwide, primarily in the tropical region, but they now pose serious threat in the temperate region as well. Global tourism and international trade have brought several invasive mosuito species into Europe, which can spread pathogens that are far more dangerous than what the native European species harbour.

Ticks

As a consequence of their blood-feeding behaviour, ticks can transmit a huge variety of pathogens. Among the several dozens of viruses, bacteria and single-celled parasites the best-known are tick-borne encephalitis virus, Borrelia burgdorferi, the bacteria causing Lyme disease and Babesia canis causing severe disease in dogs. Ticks have perfectly adapted to their natural environment where they spend most of their several years-long life. They usually tolerate changes of environment, weather and climate well and can survive in a dormant stage during hot summers or cold winters. Continue ››
