Küresel Isınma ve Parazitler

Küresel ısınmanın mevcudiyeti hakkında artık bilimsel çevrelerde bir görüş birliği oluşmuştur. Küresel ısınmanın dünyayı parazitler için daha iyi bir yer haline getireceği, daha önce karasal iklim bölgelerinde görülmeyen tropikal parazit hastalıklarının buralarda yaygınlaşacağı söylenmektedir. Sıcaklıktaki artışlar genellikle değişken sıcaklı (Poikloterm) arakonakları kullanan parazitlerin gelişme sürelerini azaltmaya başlamıştır. Küresel ısınma hastalık vektörü olarak hizmet eden ısırıcı sinekler veya kenelerin büyük ihtimalle yıl boyunca canlı kalmasını sağlayarak hayvan hastalıklarının veya Kırım-Kongo kanamalı ateşi hastalığı gibi insan hastalıklarının ortaya çıkma riskini arttırmaktadır. Şayet düşen yağış miktarı artarsa bu durum zoonoz hastalıklarda dahil olmak üzere birçok hastalığın yayılmasında bir artışa katkıda bulunabilir. Bu arada küresel ısınmanın büyük bir felakete yol açmayacağını ve zamanla konak-parazit arasında yani av-avcı arasındaki bir dengenin kurulacağı da bazı ilim adamları tarafından iddia edilmektedir

Global Warming and Parasites

A consensus about existence of the global warming has formed among scientific community. It has been said that global warming will make the world as a better place for parasites, and tropical parasitic diseases previously unseen in the areas of continental climatic zones will be widespread around here. Increases in temperature help to reduce the development periods of parasites which use poikloterm intermediate hosts. Global warming provides biting flies or ticks which serve as vectors of diseases to remain alive throughout the year, and that increases the risk of occurrence of animal diseases or human diseases such as Crimean-Congo hemorrhagic fever. If the amount of rain falling increases, this situation may contribute on the spread of a lot of diseases, including zoonotic diseases. Meanwhile, some scientists claim that global warming will not lead to a major disaster, and a balance wil be set between the host-parasite or the predator-prey in course of time
