Norovirus, commonly known as the stomach bug, has been spreading quickly in the northeastern parts of the United States. Norovirus is a highly contagious virus that leads to vomiting, diarrhoea, nausea, and stomach pain, according to the US Centers for Disease Control and Prevention (CDC). Despite often being dubbed the “stomach flu,” it’s not related to influenza.
Norovirus spreads through various means, including direct contact with an infected person, consuming contaminated food or water, and touching contaminated surfaces, followed by touching the mouth or eating without washing hands.
Symptoms of norovirus typically emerge 12 to 48 hours after exposure and include nausea, vomiting, diarrhoea, stomach cramps, low-grade fever, and muscle pain.
While the illness is usually short-lived, lasting less than three days, it can be particularly severe for young children, the elderly, and individuals with a weak immune system.
The CDC emphasises the importance of thorough handwashing with soap and water for at least 20 seconds, especially after using the toilet or changing diapers and before preparing or consuming food, as the cornerstone of prevention.
Alcohol-based hand sanitisers are less effective against norovirus.
Additional preventive measures include rinsing fruits and vegetables, staying home when sick, and avoiding food preparation for others until two days after symptoms have ceased.
