巴西大西洋森林的蚊子由于栖息地丧失、疾病风险增加而更频繁地咬人。 Mosquitoes in Brazil’s Atlantic Forest are biting humans more often due to habitat loss, increasing disease risk.

一项新研究发现,巴西大西洋森林的蚊子由于生境丧失和野生生物减少,正在越来越多地咬人。 Mosquitoes in Brazil’s Atlantic Forest are increasingly biting humans due to habitat loss and declining wildlife, a new study finds. 蚊虫转向人们, 增加了登革热、Zika、Chikungunya等疾病的风险。 With fewer animal hosts available, mosquitoes are turning to people, raising the risk of diseases like dengue, Zika, and chikungunya. 捕获的蚊子血样中18个样本中显示出人类DNA, 其他样本来自鸟类,狗,老鼠和两动物. DNA analysis of blood meals from captured mosquitoes showed human DNA in 18 out of 24 samples, with others from birds, a dog, mouse, and amphibian. 研究人员警告这一转变会增加疾病传播的风险,并呼吁采取包括生态系统保护在内的公共卫生战略。 Researchers warn the shift increases disease transmission risk and call for public health strategies that include ecosystem conservation.
