Norovirus Is Leading Cause of U.S. Hospital Infectious Outbreaks: Report

Norovirus Is Leading Cause of U.S. Hospital Infectious Outbreaks: Report

Norovirus infections accounted for 18.2 percent of outbreaks and 65 percent of closures of hospital wards during 2008 and 2009, according to the study published in the American Journal of Infection Control. The report was compiled by researchers from the Association for Professionals in Infection Control and Epidemiology Consulting Services and the Lexington Insurance Company.

responsible for most of viral gastroenteritis outbreaks

Genogroup II noroviruses are non enveloped and single strand RNA viruses. These human enteric viruses are responsible for most of viral gastroenteritis outbreaks. They are pathogenic for all age groups of the population. These viruses are very infectious; one to ten viral particles are sufficient to get sick.

FOOD poisoning

Their mode of transmission is the feco-oral route. After excretion in human stool, due to their structural properties, noroviruses can resist to different physical and chemical treatment. Adsorbed on particles, they can survive in different types of environment for a long period. Food samples can be contaminated via food handlers or by the environment. Due to their structural properties, norovirus can survive to different food processes. The consumption of contaminated food can lead to human outbreak.

methods of choice for NoV detection

There is no cell culture available for the multiplication of human noroviruses. The detection by ELISA is not recommended due to norovirus genetic diversity and its lack of sensitivity. Molecular techniques (real time RT-PCR) are the methods of choice for NoV detection after extraction and viral RNA purification from the sample.
