These symptoms include nausea, vomiting, diarrhea, abdominal pain, headache, and low-grade fever. People infected with norovirus usually recover in two to three days without serious or long-term health effects. Although symptoms usually only last one to two days in healthy individuals, norovirus infection can become quite serious in children, the elderly, and immune-compromised individuals. In some cases, severe dehydration, malnutrition, and even death can result from norovirus infection, especially among children and older and immune-compromised adults in hospitals and nursing homes. In England and Wales, 20% of those over the age of 65 die due to infectious intestinal illness other than Clostridium difficile. Recently, there have been reports of some long-term effects associated with norovirus, including necrotizing entercolitis, chronic diarrhea, and post-infectious irritable bowel syndrome, but more data is needed to support these claims. ### Other Norovirus Lawsuits [240 with Norovirus linked to Sushi Nine](https://marlerclark.com/240-with-norovirus-linked-to-sushi-nine) [Norovirus Outbreak Tied to
