Nausea is a hallmark symptom associated with Norovirus infection. This virus is widely recognized for causing acute gastroenteritis, which is characterized by inflammation of the stomach and intestines. One of the primary manifestations of this condition is nausea, often accompanied by vomiting. The reason other symptoms are not correct choices is that, while skin rash and loss of appetite can occur due to various infections, they are not specifically indicative of Norovirus. Skin rashes are more related to allergic reactions or other viral infections, while loss of appetite can be a general symptom in many illnesses and does not directly point to Norovirus. Difficulty breathing is associated with more severe respiratory infections or allergic reactions and is not a symptom typically linked to gastrointestinal viruses like Norovirus. Therefore, nausea stands out as the correct and most relevant symptom of Norovirus infection.
