Worldwide, norovirus has been estimated to cause 18% of all acute gastroenteritis cases [1], ranging from mild to severe (hospitalized).Norovirus infection is generally seen as a mild and self-limiting acute gastroenteritis. However, less well understood are potentially severe or long-term effects after a norovirus infection. Norovirus is found to be associated with mortality in studies using outbreak data, syndromic surveillance, or case-based death certificates [2 –6]. In addition to mortality, norovirus illness has been reported in relation to several severe or life-threatening complications as well as chronic seq...

This study investigated norovirus contamination of groundwater treatment systems at 1360 sites in seven metropolitan areas and nine provinces in 2015-2016. Temperature, pH, residual chlorine, and turbidity content were assessed to analyze the water quality. In 2015, six sites were positive for the presence of NoV (0.88%) and in 2016, two sites were positive (0.29%); in total, NoV was detected in 8 of the 1360 sample sites (0.59%) investigated. Identified genotypes of NoV in groundwater included GI.5, 9 and GII.4, 6, 13, 17, and 21. GII.17 was the most prevalent genotype in treated groundwater used in the food industry. Thi...

Abstract One-year surveillance for enteric viruses in raw sewage was conducted in Kansai area, central part of Japan from July 2015 to June 2016. The raw sewage was collected monthly from an inlet polluted pool and was concentrated by polyethylene glycol (PEG) precipitation. Twelve sewage samples were screened for nineteen kinds of enteric viruses by using RT-PCR method and further analyzed by nucleotide sequencing. Twelve enteric viruses were found in the investigative sewage samples. Rotavirus A and norovirus GI and GII with several genotypes were detected all year round. Interestingly, norovirus GII.17 (Kawasak...

Raw Canadian oysters are likely behind a norovirus outbreak that has both Canadian and American health officials warning consumers to use caution. The California Department of Public Health on Tuesday said that approximately 100 people there have become sick after eating oysters from Baynes Sound in British Columbia. The department said several people have tested positive for norovirus, a highly contagious infection that causes inflammation of the stomach and/or intestines and results in symptoms including vomiting, diarrhea, nausea, fever and stomach pain. Nearly 200 people in Canada have reported gastrointestinal illnes...

(Washington University School of Medicine) Researchers have shown, in mice, that norovirus infects a rare type of intestinal cell called a tuft cell. Noroviruses tucked inside tuft cells are effectively hidden from the immune system, which could explain why some people continue to shed virus long after they are no longer sick. These 'healthy carriers' are thought to be the source of norovirus outbreaks, so understanding how the virus evades detection in such people could lead to better ways to prevent outbreaks.
