Invasive Asian Longhorned Tick Spreading Widely in U.S.

The Centers for Disease Control and Prevention is working with public health, agricultural, and academic experts to understand the possible threat posed by the spread of the Asian longhorned tick (Haemaphysalis longicornis) in several U.S. states since its discovery in 2017, according to today’s Morbidity and Mortality Weekly Report.

“The full public health and agricultural impact of this tick discovery and spread is unknown,” said Ben Beard, ...

Researchers discover how ‘cryptic’ connections in disease transmission influence epidemics

Diseases have repeatedly spilled over from wildlife to humans, causing local to global epidemics, such as HIV/AIDS, Ebola, SARS, and Nipah.

A new study by researchers of disease transmission in bats has broad implications for understanding hidden or “cryptic” connections that can spread diseases between species and lead to large-scale outbreaks.

By dusting bats with a fluorescent powder that glows under ultraviolet ...

Surface water and flood dynamics increase vulnerability to waterborne disease and climate change

Diarrheal disease, a preventable and treatable illness, remains the second-leading cause of death in children under the age of 5 and a persistent public health threat in sub-Saharan Africa.

Researchers have now uncovered how surface water dynamics may increase the vulnerability of dependent populations to diarrheal disease and climate change.

Kathleen Alexander, professor of wildlife in Virginia Tech’s College of ...

Recap from the 2018 VectorBiTE workshop

VectorBiTE: Vector Behavior in Transmission Ecology by the Quantitative Ecological Dynamics Lab

JUNE 21, 2018  |  BY FADOUA EL MOUSTAID

The Quantitative Ecological Dynamics Lab, led by Leah Johnson, just wrapped up a third VectorBiTE workshop at the Asilomar Conference Center in Pacific Grove, CA. The VectorBiTE project is a Research Coordination Network that seeks to build a collaborative network of interdisciplinary researchers to investigate the effect of vector behavior and life history on transmission dynamics. More about the goals and the organizing team can be ...

Dr. Dana Hawley leads research linking bird immunity and pathogen virulence

From VT News

March 1, 2018  |  As annual flu shot patrons know, immune systems are not perfect and must be constantly reinforced to protect against rapidly evolving pathogens.

New research shows that, in the case of a common backyard bird, imperfect immunity to a dangerous pathogen that causes “bird pink eye” actually makes the pathogen stronger and more dangerous for its next victim.  The findings — from a multi-university team led ...

Climate change could wipe out a third of parasite species

From The Guardian:

Climate change could wipe out a third of all parasite species on Earth, according to the most comprehensive analysis to date.

Tapeworms, roundworms, ticks, lice and fleas are feared for the diseases they cause or carry, but scientists warn that they also play a vital role in ecosystems. Major extinctions among parasites could lead to unpredictable invasions of surviving parasites into new areas, affecting wildlife and humans and making a “significant contribution” to the sixth ...
