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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
