بررسی تأثیر تغییرات اقلیمی بر روی بیماری های انگلی

Introduction: Climate changes are one of the factors associated with human activities for the destruction of the ecosystem. This factor leads to global warming, changing rainfall patterns, increasing the amount and severity of climate factors such as storms, and rising sea levels. Parasites are also an integral part of this ecosystem; therefore, the present study considered the effect of climate change on these diseases. Methods and Materials: This review article has been performed by searching “climate change”, “climate variability”, “Global warming”, “parasitic disease”, “food and water- borne diseases”, “vector-borne diseases” and “Soil-borne diseases” keywords in international databases and scientific sources from 1996 to 2016. Results: Parasitic protozoans are more affected by climate changes compared to stem cells such as worms. These climatic conditions change the temporal and spatial patterns of the disease particularly the protozoan diseases. Worms diseases such as fasiilliasis and schistosomiasis, as well as the range of Trematoids are affected by climate changes due to the presence of the host snail in the life span of these parasites. Moreover, protozoan diseases including malaria and leishmaniasis are sensitive to climate changes because of the presence of multiple carriers and reservoirs in their transmission cycles. Discussion and Conclusion: Many parasitic diseases have high potential for vulnerability against new weather conditions due to the free life cycle and numerous animal hosts directly exposed to these climatic conditions. For these diseases, climate changs can shift the boundaries for ecosystem components and provide the conditions for the transmission and prolongation of parasites.
