Beyond Rotavirus: Persistence of Norovirus, Adenovirus, and Astrovirus in Paediatric Gastroenteritis in the Republic of Congo After Vaccine Introduction. [PDF]

J Med Virol
ABSTRACT Despite the introduction of rotavirus vaccines, gastroenteritis remains a major cause of paediatric morbidity and mortality in the Republic of Congo. This study investigated the prevalence and genetic diversity of non‐rotavirus enteric viruses including norovirus (NoV), adenovirus (AdV), and astrovirus (AstV) ten years after the introduction ...

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

Association between breastfeeding, host genetic factors, and calicivirus gastroenteritis in a Nicaraguan birth cohort.

PLoS ONE, 2022
BackgroundNorovirus and sapovirus are important causes of childhood acute gastroenteritis (AGE). Breastfeeding prevents AGE generally; however, it is unknown if breastfeeding prevents AGE caused specifically by norovirus and sapovirus.MethodsWe ...

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

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 ...

Investigation of genotype diversity of 7,804 norovirus sequences in humans and animals of China

Open Life Sciences, 2022
Norovirus is a prominent enteric virus responsible for severe acute gastroenteritis disease burden worldwide. In our current study, we analyzed 7,804 norovirus sequences of human and animals in China which were detected from 1980 to 2020 from GenBank ...

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,

Norovirus recombination

Journal of General Virology, 2007
RNA recombination is a significant driving force in viral evolution. Increased awareness of recombination within the genusNorovirusof the familyCalicivirushas led to a rise in the identification of norovirus (NoV) recombinants and they are now reported at high frequency.

Review Norovirus

Uirusu, 2020
Noroviruses commonly cause infectious gastroenteritis and massive food poisoning. There is an urgent need to elucidate the infection mechanism of noroviruses and to develop vaccines and therapeutic drugs. In addition to human disease, noroviruses have been implicated in animal disease.
