New NSF-NIH-USDA-BBSRC grants fund research on how infectious diseases are transmitted
West Nile virus, Lyme disease and hantavirus are all infectious diseases spreading in animals and in people. Is human interaction with the environment somehow responsible for the increase in incidence of these diseases? (more…)
Save the tick that bites you: it may not be the one you think
This year’s mild winter and early spring were a bonanza for tick populations in the eastern United States. Reports of tick-borne disease rose fast.
While Lyme disease is the most common tick-borne disease in the Northeast and Upper Midwest, new research results emphasize that it is not the greatest cause for concern in most Southeastern states.
The findings are published today in a paper in the journal Zoonoses and Public Health. (more…)
*Spread highest in urbanized and agricultural habitats*
After its initial appearance in New York in 1999, West Nile virus spread across the United States in just a few years and is now well established throughout North and South America.
Both the mosquitoes that transmit it and the birds that are important hosts for the virus are abundant in areas that have been modified by human activities.
As a result, transmission of West Nile virus is highest in urbanized and agricultural habitats. (more…)
*Infectious diseases on the rise as species disappear*
Plant and animal extinctions are detrimental to your health.
That’s the conclusion of a paper published in this week’s issue of the journal Nature by scientists who studied the link between biodiversity and infectious diseases. (more…)
