Lyme Disease

Lyme disease is the most common tick-borne illness in the U.S., with nearly one-third of the nation’s cases occurring in New York. Each year, this emerging disease increases its range, putting more people in harm’s way. In the Hudson Valley, ticks can also infect people with babesiosis and anaplasmosis. While residents are becoming aware of the threat ticks pose, there is less knowledge about how environmental conditions magnify disease risk.

Of Mice & Ticks: Using Ecology to Prevent Lyme Disease

We shouldn't be afraid to take a walk in the woods. Unfortunately, blacklegged ticks have become a scourge. Dr. Rick Ostfeld will discuss: why ticks and tick-borne disease are on the rise, how wildlife influences our risk of getting sick, and ways that ecology can inform tick management and make the outdoors safer for people and pets.

Mild Winter Days? Watch Out for Ticks

Although tick encounters are less frequent in winter, there are still plenty of ticks out in the environment searching for a blood meal.

Climate change, pathogens, and people: The challenges of monitoring a moving target

For human health, one emerging concern is that we do not fully understand how the geographic ranges of vector-borne diseases—those caused by parasites, bacteria, and viruses transmitted to humans via an intermediate host organism—are being influenced by climate change.

The Tick Project

The Tick Project is testing whether environmental interventions can prevent tick-borne diseases in our communities. The need for prevention is stronger than ever, with expanding tick populations and more than 300,000 Americans diagnosed with Lyme disease each year.

Lyme Disease

Different species of tick hosts tend to have different probabilities of transmitting an infection to a feeding tick. In eastern and central North America, the host most likely to transmit an infection to a feeding tick is the white-footed mouse (Peromyscus leucopus), which infects between 40% and 90% of feeding larvae.

Biodiversity, Community Ecology, and the Dilution Effect

Biodiversity can protect human health by reducing human exposure to diseases transmitted from wildlife. Environmental changes, such as habitat fragmentation, can increase disease risk by reducing both predators and biodiversity.
