Increase of GII.17 Norovirus Infections During the 2024-2025 Season in Multiple Cities, China. [PDF]

J Med Virol
ABSTRACT A significant numerical increase of genotype GII.17 norovirus‐associated sporadic infections was observed in multiple cities in China during the 2024–2025 season. We collected fecal samples from hospitalized children with acute gastroenteritis from 29 sentinel hospitals nationwide to screen for norovirus.

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

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

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,
