Introduction
Under normal circumstances, norovirus mainly spreads through close contact. During symptom onset, the virus present in saliva, sweat, or vomit may remain on the body surface. Hugging at this time can easily lead to infection via skin contact or respiratory droplets, especially for individuals with weaker immune systems who face a higher risk of infection, potentially leading to symptoms such as vomiting and diarrhea.
Generally, it is not recommended to hold or hug someone with norovirus if their symptoms have not yet subsided. Brief contact may be acceptable after symptoms have completely disappeared and proper hygiene measures have been taken. If in doubt, it is advisable to consult a healthcare professional in advance. Detailed analysis is as follows:
Norovirus primarily spreads through close contact. During the symptomatic phase, the virus present in saliva, sweat, or residual vomit may adhere to the body's surface. Hugging at this stage can easily lead to infection via skin contact or respiratory droplets, especially for individuals with weakened immune systems who face a higher risk of infection, potentially leading to symptoms such as vomiting and diarrhea.
If the patient’s symptoms have fully resolved and thorough cleaning has been performed (such as showering and changing clothes), most of the virus in the body will have been eliminated, significantly reducing the risk of transmission during brief physical contact. However, overly intimate contact should still be avoided to minimize the possibility of spreading any residual virus.
In daily life, it is important to maintain personal hygiene—wash and disinfect hands promptly after contact with infected individuals, and thoroughly clean any items used by the patient to prevent indirect transmission of the virus.
