Introduction
In general, norovirus infection typically resolves on its own within 1 to 3 days. The exact duration may vary depending on the severity of the infection and individual physical condition. Most healthy individuals recover relatively quickly and do not require specific antiviral treatment. It is recommended to consume light, easily digestible liquid or semi-liquid foods, such as millet porridge and noodle soup, while avoiding greasy and cold foods that may加重 gastrointestinal burden.
Under normal circumstances, norovirus infection usually resolves spontaneously within 1-3 days. The exact duration may be influenced by the severity of infection and individual physical condition. Most healthy individuals recover relatively quickly and generally do not require specific antiviral treatment. Detailed analysis is as follows:
Healthy adults infected with norovirus typically experience acute gastrointestinal symptoms such as nausea, vomiting, diarrhea, and abdominal pain. These symptoms are usually mild, and the body's immune system can eliminate the virus within 1-2 days. Symptoms gradually improve, and most individuals recover fully within 3 days without causing long-term damage to the body.
In children, elderly individuals, or those with weakened immune systems, symptoms may be more severe after infection—for example, more frequent vomiting or increased frequency of diarrhea. Recovery may take up to about 3 days, but most cases still resolve spontaneously within a week. Particular attention should be given to hydration and electrolyte replacement in these populations to prevent dehydration or electrolyte imbalance caused by vomiting and diarrhea.
During the infection period, it is important to drink plenty of warm water or lightly salted water to replenish lost fluids and electrolytes. Diet should primarily consist of light, easily digestible liquid or semi-liquid foods, such as millet porridge and noodle soup. Avoid greasy or cold foods that may increase gastrointestinal burden.
