Norovirus is a highly contagious virus that affects the digestive tract and causes symptoms such as diarrhea, vomiting, nausea, and stomach cramps. It is the leading cause of gastroenteritis, or inflammation of the stomach and intestines, in the United States. While anyone can contract norovirus, certain groups are particularly susceptible to it.
Children and older adults are most at risk for contracting norovirus. This is due to their weaker immune systems and lower natural defenses. Young children are especially vulnerable to the virus, as their immune systems are still developing and they are more likely to come into contact with contaminated food or surfaces. Elderly individuals are also at higher risk due to their weakened immune systems and the fact that they may have chronic health conditions that make them more susceptible to infection.
Individuals with weakened immune systems, such as those with HIV/AIDS or cancer, may also be more likely to contract norovirus. People who are taking certain medications such as steroids or chemotherapy drugs may be more prone to infection due to their weakened immune systems.
Those who live in close quarters, such as nursing homes and hospitals, are also more at risk of contracting norovirus. This is because it is easily spread from person to person through contact with contaminated surfaces or food. People living in these environments are more likely to come into contact with someone who has the virus.
In addition, people who travel, particularly by cruise ships or airplanes, are at a higher risk of contracting norovirus. This is because the virus can be easily spread in these enclosed environments.
By taking certain precautions, such as washing hands regularly, avoiding contact with those who are ill, and thoroughly cooking food, anyone can reduce their risk of contracting norovirus.
