In developing countries, Norovirus is the second-leading cause of acute diarrhea, after rotavirus. The approved gold standard method for diagnosis norovirus infection RT-PCR. rapid immunochromatographic test a novel and expedient diagnosing that relatively affordable. However, use remains controversial because its accuracy. This study aimed to explore whether could be used norovirus-related dia...

conclusions regarding the emergence of noroviruses as a relevant cause of acute diarrhea in iranian children, there is a great need to introduce a routine norovirus testing of hospitalized patients with gastroenteritis, particularly in children under 2 years old during the cold season. results of the total collected samples, noroviruses were detected in 47 out of 375 (12.53%). the highest infec...

Rotavirus and norovirus are important etiologies of gastroenteritis among hospitalized children. During 2012-2013, we tested 207 residual stool specimens from children with healthcare-associated vomiting and/or diarrhea for rotavirus and norovirus. Twenty (10%) were rotavirus positive, and 3 (3%) were norovirus positive, stressing the importance of these pathogens in hospitalized children.

We conducted sentinel-based surveillance for norovirus in the Pudong area of Shanghai, China, during 2012-2013, by analyzing 5,324 community surveys, 408,024 medical records, and 771 laboratory-confirmed norovirus infections among 3,877 diarrhea cases. Our analysis indicated an outpatient incidence of 1.5/100 person-years and a community incidence of 8.9/100 person-years for norovirus-associate...

Norovirus is the leading cause of foodborne disease in the United States. During October 2011-January 2013, we conducted surveillance for norovirus infection in Minnesota among callers to a complaint-based foodborne illness hotline who reported diarrhea or vomiting. Of 241 complainants tested, 127 (52.7%) were positive for norovirus.

Norovirus is the most common cause of viral foodborne illness worldwide. A new study suggests that contaminated water used to dilute or reconstitute agricultural pesticides may be one way the virus is entering the food supply. Farmers mix pesticides with water from sources including wells, irrigation ditches, rivers, and lakes. All these water sources have been known to harbor norovirus. Until ...

A typical clinical symptom of human norovirus infection is projectile vomiting. Although RNA and viral particles have been detected in vomitus, infectivity has not yet reported. We replication-competent 25% vomit samples with a 13-fold to 714-fold increase genomic equivalents, confirming infectious norovirus.

Homologous recombination is one of the driving forces contributing to the genetic variation of human norovirus, which is an important cause of sporadic and epidemic acute gastroenteritis globally. We report the near-complete genome of the novel recombinant norovirus strain GII.P7-GII.6, detected in an adult with norovirus gastroenteritis in the United States.

BACKGROUND The burden of disease due to norovirus infection has been well described in the general United States population, but studies of norovirus occurrence among persons with chronic medical conditions have been limited mostly to the immunocompromised. We assessed the impact of norovirus gastroenteritis on health care utilization in US subjects with a range of chronic medical conditions. ...

A 48-year-old female with abdominal pain and malaise who showed delayed symptom of acute gastroenteritis came to see us. Her illness was diagnosed as norovirus infection, but liver dysfunction accompanied this gastroenteritis. We investigated the pathogenesis of this hepatitis for all causes including drugs, but we could not detect norovirus infection. The liver damage improved shortly in cours...
