Without a virus culture system, genetic analysis becomes the principal method to classify
norovirus (NoV) strains. Currently, classification of NoV strains beneath the species level has …

Between July 2000 and June 2004, fecal specimens from 270 outbreaks of acute gastroenteritis
were sent to the Centers for Disease Control and Prevention by local or state health …

Nearly all human beings, by the time they reach adolescence, are infected with multiple
herpesviruses. At any given time, this family of viruses accounts for 35–40 billion human …

Efforts to prevent foodborne illness target bacterial pathogens, yet noroviruses (NoV) are
suspected to be the most common cause of gastroenteritis. New molecular assays allow for …

In 2002, a sharp increase in outbreaks of norovirus-associated illness, both on cruise ships
and on land, encouraged us to examine the molecular epidemiology of detected noroviruses, …

We describe an investigation of a norovirus gastroenteritis outbreak aboard a cruise ship
affecting 6 consecutive cruises and the use of sequence analysis to determine modes of virus …

(See the editorial commentary by Jones, on pages 1334–5 .) Background. Acute gastroenteritis
(AGE) remains a common cause of clinic visits and hospitalizations in the United States, …

Norwalk-like viruses'(NLVs) cause outbreaks of gastroenteritis and are spread frequently
through contaminated food or water. Molecular diagnostics now enables detecting viruses in …

In February 2001, episodes of acute gastroenteritis were reported to the Wyoming Department
of Health from persons who had recently vacationed at a snowmobile lodge in Wyoming. …

To better assess the risk for transmission of the severe acute respiratory syndrome–associated
coronavirus (SARS-CoV), we obtained serial specimens and clinical and exposure data …
