Which groups are at higher risk for Norovirus infection?

Norovirus shows up most in groups whose bodies are more vulnerable to infection or to dehydration from illness. Children, older adults, and people with weakened immune systems are at higher risk because their defenses are less able to fight off the virus and they’re more likely to experience complications from the illness. Young children have developing immune systems and spend lots of time in close contact settings like daycare or schools, which facilitates rapid spread. Older adults often have aging immune systems and multiple health conditions, and they may live in close quarters where viruses spread easily. Those with weakened immune systems, such as people with chronic diseases, cancer, or on immunosuppressive medications, are particularly susceptible and can have more severe or prolonged illness. Norovirus is highly contagious and requires only a tiny amount to cause infection, so outbreaks can spread quickly in environments where these groups are present. Athletes and healthcare workers can encounter the virus due to exposure, but their overall risk of infection isn’t inherently higher than the general population; it’s the specific vulnerability of the three groups mentioned that drives their higher risk. Pregnant women aren’t at uniquely increased risk for Norovirus infection compared with others.
