How long can Norovirus survive on surfaces?

Norovirus is known for its resilience in the environment, particularly on surfaces. It can survive on various surfaces for a period ranging between 8 hours and 7 days. This persistence is significant because it contributes to the spread of infection, especially in settings like nursing homes where close contact among residents can facilitate transmission.

Understanding the survival duration of Norovirus on surfaces is crucial for infection prevention practices. Cleaning and disinfecting surfaces that may be contaminated is essential for controlling outbreaks since the virus can remain infectious for an extended period. Options that suggest a shorter survival time, such as less than 1 hour or 2 days, underestimate the longevity of the virus on surfaces, while indicating a survival period of more than 2 weeks does not align with the known data on Norovirus. Thus, the correct response reflects the reality of how long Norovirus can remain viable on surfaces, emphasizing the need for diligent sanitation measures in infection control efforts.
