In December 2024, Lyme disease cases reached a record high in Maine with over 3,035 infections. Rising rates in Lyme disease have been seen as a result of climate change. Warmer temperatures and changes in weather patterns has created an ideal environment for ticks transmitting the disease.

In December 2024, Maine reported an alarming milestone: over 3,035 Lyme disease infections, the highest ever recorded in the state. As climate change accelerates, so does the spread of ticks. Warmer temperatures and shifting weather patterns are creating a perfect storm for ticks to thrive, increasing the risk of Lyme disease for humans and pets alike.

Here's how:

1. Longer Active Seasons: Ticks are most active during warmer months, and, due to climate change, winters have become milder and shorter, giving tick populations longer periods to reproduce, feed, and spread. This extended activity season increases the likelihood of human and animal exposure and contraction of Lyme.

2. Geographic Expansion: Warmer climates are enabling ticks to survive in regions that were previously too cold, including areas in northern parts of the U.S., Canada, and Europe, which has exposed new populations to the risks of tick-borne illnesses.

3. Humidity and Tick Survival: Ticks rely on humid environments to stay hydrated. Climate change has led to increased humidity in some regions, creating an environment for ticks to thrive.

Ecological Changes: The Role of Wildlife in Tick Distribution

Ticks depend on animal hosts for survival and reproduction, so changes in wildlife populations have also had a significant impact on tick-borne disease rates:

1. Deer Populations: White-tailed deer are a primary host for adult ticks. As deer populations grow due to reduced predation and increased suburbanization, ticks have more opportunities to reproduce and spread. Suburban areas with abundant deer often see higher rates of Lyme disease.

2. Rodents and Small Mammals: Mice and other small mammals also act as hosts for immature ticks (larvae and nymphs) and play a crucial role in the transmission of Borrelia burgdorferi. Therefore, changes in rodent populations have contributed to the increase in cases of Lyme.

3. Bird Migration: Migratory birds can also carry ticks over long distances, allowing them to bring ticks to new geographic areas. As climate change alters migration patterns, it may contribute to the spread of tick populations and therefore Lyme disease.

Human Impact: Expanding Risk Areas

The intersection of human activity and environmental changes amplifies the risks:

1. Urbanization and Suburban Development: As humans encroach on natural habitats, we increase our exposure to ticks. Suburban neighborhoods near wooded areas or parks often have high tick densities, putting residents at greater risk for contracting a tick-borne illness.

2. Outdoor Activities: Warmer weather due to climate change encourages outdoor recreation, increasing the chances of encountering a tick. Activities like hiking, gardening, and camping expose individuals to tick habitats.
