Study says mice are super hosts of Lyme ticks

While bloodsucking ticks can lay waste to a moose and infect humans with devastating diseases, the tiny parasites and the bacteria they carry have no apparent effect on one wee woodland creature: the white-footed mouse.

As climate change alters ecosystems, scientists worry that exotic diseases will spread

Another public health challenge the National Climate Assessment will explore is the likelihood that diseases native to other geographical areas will migrate to the United States as climate changes alter ecosystems.

Capitol Hill briefing: Climate change and infectious disease

Audio
Speakers: Richard Ostfeld and George Luber

Topics covered include the controversy over whether climate change will increase the burden of infectious disease with a focus on malaria and other mosquito-transmitted diseases.

How the spreading symptoms of climate change can be deadly

The hallmarks of a warming climate, heavier rains, more severe droughts, rising sea levels and longer growing seasons, are spreading a variety of pathogens throughout the world.

Lyme disease: Freezes may reduce ticks

A 2012 study co-authored by Cary Disease Ecologist Rick Ostfeld examined the probability of tick mortality in winter conditions in Millbrook and Syracuse.

Dengue fever: Another formidable World Cup opponent

Brazil is a hot spot for dengue fever, a mosquito-transmitted virus that lacks a vaccine or treatment. The nation's 573 dengue deaths in 2013 through Nov. 20 is nearly double the 2012 toll.

Diseases on the move because of climate change

Warming temperatures and increased extreme weather events such as drought, rainstorms and flooding, contribute to the nation's changing disease map, experts say. USA Today reports on this trend and how it has impacted the spread of various diseases including tick-borne illnesses.

An interview with Rick Ostfeld

Initially, Rick Ostfeld’s work at the Cary Institute focused on how small mammals shape forests. Early on, he noticed a unique relationship among mice, black-legged ticks, and the bacterium that causes Lyme disease.

The human health costs of losing natural systems

A new paper from members of the HEAL (Health & Ecosystems: Analysis of Linkages) consortium delineates a new branch of environmental health that focuses on the public health risks of human-caused changes to Earth’s natural systems.

Tracking disease in a warming world

Podcast

Understanding how infectious diseases respond to climate change would help public health officials and environmental managers predict and mitigate disease impacts.

The global search for education: Prevention - ticks

Given the 300,000 new cases of Lyme disease a year in the US reported by the CDC, it is understandable that health organizations and local governments in this country are extremely anxious to develop a broader, more effective tick-borne diseases control strategy.

More tickborne diseases other than Lyme. Maybe just don’t go outside.

Some tick-borne diseases are just becoming known and thus are often not recognized by physicians.

Climate change affects disease spread: The need to forecast

As our climate shifts and changes, wildlife and weather also shifts and changes. Now, researchers have found something else that's deviating from the norm.

Tick-borne virus risk increases

While extremely rare, Powassan virus is deadlier than other tick-borne illnesses — killing 30 percent of those infected statewide since 2004 — and its victims are infected much more quickly.

Study highlights need to forecast how climate is impacting disease risk

Climate change is affecting the spread of infectious diseases worldwide, according to an international team of leading disease ecologists.

Study finds ticks linked to Encephalitis in NYS

A recent study shows a link between a certain type of tick and a rare illness. The report shows the virus is on the rise in parts of the Hudson Valley and has spread to the Capital District.

Black-legged ticks linked to Encephalitis in New York State

In the Northeast, the black-legged ticks (Ixodes scapularis) that spread Lyme disease also infect people with other maladies, among them anaplasmosis, babesiosis, and – as a new paper in the journal Parasites and Vectors reports – Powassan encephalitis.

Another reason to be ticked off

Podcast

It’s time to add another tongue-tying illness to the list of maladies carried by ticks. Lyme disease is the most common tick-borne illness in the U. S., with more than 30,000 people infected annually.

A tiny invader that's driving people indoors

Podcast

The Asian tiger mosquito is yet another invasive species that has taken hold in the United States. It arrived here in 1985 in a shipment of tires imported from Asia.  This little mosquito is an aggressive human biter capable of transmitting diseases.

NYC forum: Silent Epidemic of Lyme and Tick-Borne Diseases

Video
Three members of Congress joined forces with a Lyme disease advocacy group to host a forum to discuss the fight against tick-borne diseases. As a panelist, Cary's Rick Ostfeld shared his research and insights.

Frankenbug?

Podcast

There are few creatures more deadly than the tiny Aedes aegypti mosquito, which transmits malaria, dengue fever and other infectious diseases.  Malaria is one of the world’s great killers, claiming about 800,000 lives each year.  We can, of course, drain wetlands and spray large areas with insecticides to kill these mosquitoes. 

Kentucky birds, New York rats raise disease risks, climate change concerns

Man-induced changes to the natural environment may be the perfect storm for the spread of diseases such as histoplasmosis, hantavirus, Lyme and typhus.

Resettled rats torment New Yorkers in Sandy's wake

Huffington Post follows-up on disease ecologist Rick Ostfeld's warning of increased health risks related to urban rats being displaced by Hurricane Sandy.

Hurricane Sandy could displace rats, spread infectious disease

In the aftermath of Hurricane Sandy, Cary's Rick Ostfeld warns of an increased risk of infectious disease due to storm waters displacing urban rats.

The ecology of disease

When we do things in an ecosystem that erode biodiversity — we chop forests into bits or replace habitat with agricultural fields — we tend to get rid of species that serve a protective role. 

acorns

Where did all the acorns go?

Podcast

For many years, oaks in the Northeast were prolific acorn producers. The 2010 crop was record-breaking—many will recall getting hit with acorn rain or slipping on acorns underfoot. Last fall, however, acorns were scarce.

In wild animals, charting the pathways of disease

New York Times article explores the links between wildlife and infectious diseases.

Understanding tick-borne diseases

Millbrook, NY – The Hudson Valley has the unfortunate distinction of being the global epicenter of tick-borne disease. And the situation is getting worse.

Deadly frog disease illustrates dangers of wildlife trade

The forest, normally filled with the chorus of calling frogs, falls silent. Something drops from the trees. And then another. Dead frogs are falling from the canopy.

Summer storms offer perfect weather for mosquito breeding

We've had a wet stretch of weather. First we were drenched by Irene, then again with Lee. Saturated soils had additional rainy days. And as a result, mosquitoes have been out in droves.

West Nile virus beats winter

Scientists are now realizing that animal and human activities during winter play a critical role in the persistence of West Nile virus.

West Nile virus alters ecological balance

West Nile virus is a human health risk because it can cause sickness and death when mosquitoes transmit the pathogen from an infected bird to a person.

Hardy mosquitoes defy humans, shape course of history

The joy in seeing the first flowers of spring is always countered by dismay over the reappearance of mosquitoes

Biodiversity and human health: Why more species mean fewer cases of Lyme disease

The United Nations has proclaimed 2010 to be the International Year of Biodiversity. 

Economic downturn could hurt your health

Dengue (pronounced DEN-ghee) fever is caused by a virus spread by mosquitoes. It was formerly called "break-bone fever" because it causes excruciating pain to the muscles and joints of its human victims.
