Risk Factors for Norovirus Infections and Their Association with Childhood Growth: Findings from a Multi-Country Birth Cohort Study

Viruses, 2022
The prevalence of norovirus infections in different geographical locations and their attribution to childhood diarrhea is well established. However, there are no reports showing possible relationships of different norovirus genogroups with subsequent ...

Viable Norovirus Persistence in Water Microcosms.

Environmental Science and Technology Letters, 2022
Human noroviruses are one of the leading causes of acute gastroenteritis worldwide. Based on quantitative microbial risk assessments, norovirus contributes the greatest infectious risk of any pathogen from exposure to sewage-contaminated water; however ...

Norovirus infection among HIV-infected patients in Abuja, Nigeria: impact of combination antiretroviral therapy status

BMC Infectious Diseases, 2023
Background Norovirus is now recognized to be major cause of gastroenteritis worldwide, with significantly higher disease burden among immunocompromised patients. This study aimed to determine the prevalence of Norovirus among HIV-infected patients and to

Bacterial extracellular vesicles control murine norovirus infection through modulation of antiviral immune responses

Frontiers in Immunology, 2022
Human norovirus is the primary cause of non-bacterial gastroenteritis globally and is the second leading cause of diarrheal deaths in children in developing countries. However, effective therapeutics which prevent or clear norovirus infection are not yet

The Importance of Secretor-Status in Norovirus Infection Following Allogeneic Hematopoietic Stem Cell Transplantation

Viruses, 2022
Background. Human secretor-status is a strong susceptibility factor for norovirus infection in immunocompetent people. The predominant norovirus genotype GII.4 almost exclusively infects secretors and is also associated with more severe symptoms. However,

Rotavirus and Norovirus Infections in Children Under 5 Years Old with Acute Gastroenteritis in Southwestern China, 2018–2020

Journal of Epidemiology and Global Health, 2022
Rotaviruses and noroviruses are important causes of acute gastroenteritis in children. While previous studies in China have mainly focused on rotavirus, we investigated the incidence of norovirus in addition to rotavirus in Southwestern China.

Advances in Norovirus Biology [PDF]

Cell Host & Microbe, 2014
Human noroviruses are a major cause of epidemic and sporadic gastroenteritis worldwide and can chronically infect immunocompromised patients. Efforts to develop effective vaccines and antivirals have been hindered by the uncultivable nature and extreme genetic diversity of human noroviruses.

Norovirus diarrhea is significantly associated with higher counts of fecal histo-blood group antigen expressing Enterobacter cloacae among black South African infants

Gut Microbes, 2021
The study tested the hypothesis that harboring high levels of histo-blood group antigen-expressing Enerobactero cloacae is a risk factor for norovirus diarrhea. The fecal E. cloacae abundance in diarrheic norovirus positive (DNP), non-diarrheic norovirus

Impact of non-pharmaceutical interventions (NPIs) for SARS-CoV-2 on norovirus outbreaks: an analysis of outbreaks reported by 9 US States

Journal of Infectious Diseases, 2021
In April 2020, the incidence of norovirus outbreaks reported to the National Outbreak Reporting System (NORS) dramatically declined. We used regression models to determine if this decline was best explained by underreporting, seasonal trends, or reduced ...
