Ticks, Climate, and Broken Forests: The Infection Link

Did you know that the way forests are split up and warmer temperatures can increase the risk of tick-borne diseases? Scientists in southern Japan studied this by looking at data from Miyazaki Prefecture. They found that the more forest edges there were and the hotter it was, the more cases of a tick-borne disease called severe fever with thrombocytopenia syndrome (SFTS) there were. Surprisingly, rainfall, the variety of big and medium-sized mammals, farmland percentage, human population, and tourist spots didn't affect SFTS cases.So, why is this important? When forests are broken up into smaller pieces, it creates more edges where ticks and animals meet people. Warmer temperatures also help ticks live longer and spread diseases more. This study shows that protecting forests and understanding how climate change affects ticks can help control these diseases.
