How long do symptoms of norovirus typically last?

Symptoms of norovirus typically last for 1 to 2 days, making this the correct choice. Norovirus is a highly contagious virus that causes gastroenteritis, leading to symptoms such as vomiting, diarrhea, stomach cramps, and nausea. While the onset of symptoms can occur suddenly, they tend to resolve relatively quickly, usually within a couple of days.

This rapid recovery is one of the reasons why norovirus can spread so easily, as individuals might feel better soon after the initial outbreak and may return to activities where they can inadvertently spread the virus to others. Understanding the typical duration of symptoms helps in managing the spread and encouraging individuals to practice proper hygiene measures during this time.

Longer symptom durations mentioned in other options are less common for norovirus and might be more aligned with other gastrointestinal illnesses.
