Norovirus Cases Rise In The US

Norovirus infections are increasing across the United States, with recent data indicating a sharp uptick in positive cases. As families gather for holiday celebrations, health authorities are urging vigilance to prevent the spread of this highly contagious virus.

Understanding Norovirus And Its Impact

Norovirus is a leading cause of acute gastroenteritis in the US and is known for rapid transmission in crowded settings. It spreads easily through contaminated food, surfaces and close contact. Anyone can contract the virus, though consuming raw oysters or shellfish raises the risk. The illness often appears suddenly and can disrupt large gatherings, especially during festive periods.

Symptoms And Onset Of Infection

Signs of the infection typically emerge 12 to 48 hours after exposure. Common symptoms include vomiting, diarrhoea, stomach cramps, nausea, fever, headache and body aches. In more severe cases, individuals may experience dehydration marked by reduced urination, dry mouth, dizziness, tearless crying in children and unusual fatigue.

Prevention Measures To Reduce Transmission

Public health agencies advise adopting strict hygiene practices to curb the spread of norovirus. Frequent handwashing, particularly after using the restroom and before meals, is essential. Cooking shellfish thoroughly, rinsing fruits and vegetables, disinfecting commonly touched surfaces and laundering contaminated clothes in hot water are recommended. Staying home for at least 48 hours after symptoms stop helps prevent further spread.
