The enzyme-linked immunosorbent assay (ELISA) was employed to analyze the binding between bacteria and MNV particles, and the. Human noroviruses (HNoVs) are a leading cause of gastroenteritis worldwide (1, 2).Asymptomatic fecal shedding of HNoVs may be important epidemiologically, as it provides a reservoir between outbreaks (1, 3-9).Some strains of murine norovirus (MNoV) also establish persistent enteric infection, providing a model for analyzing mechanisms of enteric NoV persistence and immunity in a natural host. Human norovirus (NoV) causes more than 80% of nonbacterial gastroenteritis in Europe and the United States. NoV transmission via contaminated surfaces may be significant for the spread of viruses. Therefore, measures for prevention and control, such as surface disinfection, are necessary to interrupt the dissemination of human NoV. Murine norovirus (MNV) as a surrogate for human NoV was used. Norovirus infection is highly contagious, and anyone can become infected more than once. To help prevent its spread: Wash your hands thoroughly with soap and water, especially after using the toilet or changing a diaper. Avoid contaminated food and water, including food that could have been prepared by someone who was sick Norovirus cause gastrointestinal illness to humans. Norovirus infection can cause vomiting, diarrhoea, and stomach pain. Less common symptoms are low fever, chills and headache. Vomiting can be sudden and frequent resulting in remarkable fluid loss. Death is rare but remains as a risk especially for elderly or persons with weakened immune system
