Two significant factors contribute to the lower Lyme disease infection rates in the southeastern US. First, black-legged ticks in the north attach to and feed off mammals that are efficient at carrying and spreading the bacteria that causes the disease. Ticks in the south mostly attach to lizards that aren’t as efficient of disease carriers. We also found that low tick densities at some southern sites, such as Tennessee and North Carolina, contributed to the low infection rates and low numbers of host-seeking ticks. This science can help researchers understand and predict the spread of Lyme ..read more

This is the New River, flowing north out of North Carolina into Virginia. The woods alongside the river are heavily infested with blacklegged ticks carrying the Lyme disease pathogen ... this river valley has likely acted as a corridor for southwards spread of infected ticks from VA into northwestern NC ..read more

The Tick App is a free app for smartphones, conceived to allow people living in high-risk areas for Lyme disease to participate in a 'tick exposure' study being run by researchers from Columbia University and the University of Wisconsin – Madison, members of the CDC Regional Centers for Excellence in Vector-Borne diseases. Funding for this study is being provided by the Centers for Disease Control. https://thetickapp.org/ Click on their map to explore how many Tick App users are in your area!

Tick season in Tennessee

by
6y ago
Tick season is heating up in Tennessee, with lots of lone star ticks active in the woods and my dogs has been bringing home American dog ticks each evening. These tick species can spread spotted fevers and red meat allergy, so please take precautions! Regarding Lyme disease risk, that disease is spread by blacklegged ticks ("deer ticks"). Adult blacklegged ticks are winter-active and most of them are already back down in the leaf litter by this time of year - they will reappear in late October. Over the summer, it's the nymphal life-stage of this tick species that you need to be watching for ..read more
