“…However, few studies have investigated the presence of NoVs in serum samples of children with NoVs-positive AGE [12,16,17]. In the present study we found NoVs GII in 34.1% of the stool samples collected from children admitted to hospital with AGE.…”

“…In addition to the classic symptoms of AGE (watery diarrhea, vomiting, abdominal pain, and fever), NoVs infection has been associated, though to a lesser extent, with atypical clinical conditions such as seizures [11,12], encephalopathy [13], and necrotizing enterocolitis [14,15]. It is unknown whether a relationship exists between these atypical symptoms and NoVs dissemination to outside the digestive tract, and worldwide, few studies have detected NoVs in blood samples [12,13,16,17]. …”

“…While the outcome is generally benign, including in one case in which the virus was detected in cerebrospinal fluid (CSF), magnetic resonance imaging (MRI) abnormalities and permanent neurological sequelae occurred in a patient in whom the virus was detected in plasma but not cerebrospinal fluid (80). Medici and colleagues also reported finding viral RNA in the plasma of an infected child with seizures (81). Notably, a study of 39 children with uncomplicated norovirus infection detected viral RNA in the serum of 6 (15%) cases but in the CSF of none (82).…”

SUMMARY Norovirus, an RNA virus of the family Caliciviridae , is a human enteric pathogen that causes substantial morbidity across both health care and community settings. Several factors enhance the transmissibility of norovirus, including the small inoculum required to produce infection (<100 viral particles), prolonged viral shedding, and its ability to survive in the environment. In this review, we describe the basic virology and immunology of noroviruses, the clinical disease resulting from infection and its diagnosis and management, as well as host and pathogen factors that complicate vaccine development. Additionally, we discuss overall epidemiology, infection control strategies, and global reporting efforts aimed at controlling this worldwide cause of acute gastroenteritis. Prompt implementation of infection control measures remains the mainstay of norovirus outbreak management.

“…Although human norovirus (HuNoV) infection is typically self-limiting, severe and long-term infection can occur in elderly or immunocompromised individuals (22,44,50,60,62). More recently, HuNoV infection has also been associated with necrotizing enterocolitis in infants and postinfectious irritable bowel syndrome in adults, as well as extraintestinal symptoms, such as benign infantile seizures and encephalopathy (12,37,40,45,54,59).…”

bHuman noroviruses (HuNoVs) are the major cause of epidemic, nonbacterial gastroenteritis worldwide. Due to the lack of a tractable model system and the inability to grow HuNoVs in cell culture, factors required for the norovirus (NoV) life cycle and pathogenesis in the host remain largely unknown. The discovery of murine norovirus (MNV) and the development of reversegenetics systems for this virus provide an opportunity to study these aspects of NoV infection in vitro and in vivo. Previous studies identified a single amino acid at residue 296 in the protruding (P) domain of the capsid protein that is responsible for determining the virulence of the MNV clone MNV1.CW1 in 12956/SvEv background STAT1-deficient (STAT1 ؊/؊ ) mice. In this report, we identified and characterized another determinant of lethality in the P domain that is necessary and sufficient to determine the replication and pathogenesis of the MNV clones MNV1.CW3 and CR6.STL1 in C57BL/6 background STAT1 ؊/؊ mice. Furthermore, we describe how the role of residue 296 in MNV virulence differs between STAT1 ؊/؊ mouse strains. We also describe potential interactions between subdomains of the P domain, as well as between other virus elements, which facilitate recovery of MNV using a reverse-genetics system.
