Screening the entire human genome, a team headed by Yale University scientists have identified several hundred genes that impact West Nile virus infection. The findings reported Wednesday online in the journal Nature may give scientists valuable new clues about ways to intervene in a host of deadly viral infections.

Before West Nile virus arrived in this country, we had (and still have) a home-grown relative of this pathogen. An epidemic of unknown origin exploded around St. Louis, Missouri in the autumn of 1933, a disease that is now known to be transmitted by mosquitoes from birds to people.

Severe West Nile infection could lead to lifetime of symptoms

Most people who suffer severe infection with West Nile virus still experience symptoms years after infection and many may continue to experience these symptoms for the rest of their lives according to research presented today (March 17) at the 2008 International Conference on Emerging Infectious Diseases in Atlanta, Georgia.

Researchers put the bite on mosquitoes

Few things sting like a mosquito's bite--especially if that bite carries a disease such as malaria, yellow fever, Dengue fever or West Nile virus. But if researchers from The University of Arizona in Tucson have their way, one day mosquito bites may prove deadly to the mosquitoes as well.

Simple online methods increase physician disease reporting

harminka — Mon, 14 Jan 2008 14:00:41 -0600

With emerging diseases like the West Nile Virus, and re-emerging diseases such as the pandemic flu and drug-resistant tuberculosis, it’s increasingly important to promptly detect a potential infectious outbreak within a community. But public health officials can’t act quickly unless physicians report the diseases.
