Human cases of tick-borne diseases have been increasing in the United States. In particular, the incidence of Lyme disease, the major vector-borne disease in Rhode Island, has risen, along with cases of babesiosis and anaplasmosis, all vectored by the blacklegged tick. These increases might relate, in part, to climate change, although other environmental changes in the northeastern U.S. (land use as it relates to habitat; vertebrate host populations for tick reproduction and enzootic cycling) also contribute. Lone star ticks, formerly southern in distribution, have been spreading northward, including expanded distributions in Rhode Island. Illnesses associated with this species include ehrlichiosis and alpha-gal syndrome, which are expected to increase. Ranges of other tick species have also been expanding in southern New England, including the Gulf Coast tick and the introduced Asian longhorned tick. These ticks can carry human pathogens, but the implications for human disease in Rhode Island are unclear.
美国的蜱传疾病病例一直在增加。特别是，莱姆病的发病率上升了，莱姆病是罗德岛主要的媒介传播疾病，还有巴贝斯虫病和无形体病，这些疾病都是由黑腿蜱传播的。这些增加可能部分与气候变化有关，尽管美国东北部的其他环境变化（与栖息地有关的土地利用；蜱类繁殖和内循环的脊椎动物宿主种群）也有影响。孤星蜱，以前分布在南部，已经向北扩散，包括在罗德岛的分布范围扩大。与该物种相关的疾病包括埃立克体病和α-半乳糖综合征，预计这些疾病会增加。其他蜱种的范围也在新英格兰南部扩大，包括海湾角蜱和引入的亚洲长角蜱。这些蜱可以携带人类病原体，但它们对罗德岛人类疾病的影响尚不清楚。
