Norovirus Outbreaks Surge Across the U.S.
Recent data from the Centers for Disease Control and Prevention (CDC) has unveiled a concerning spike in norovirus outbreaks in early December. The U.S. witnessed a significant increase from 69 to 91 reported outbreaks within just one week. An outbreak is identified as two or more similar illnesses stemming from a common exposure to norovirus.
Understanding Norovirus: Causes and Transmission
Norovirus is a highly contagious virus responsible for acute gastroenteritis, causing inflammation in the stomach or intestines. This virus manifests differently in each individual, with varying levels of severity. Shockingly, as few as 10 viral particles are adequate to trigger an infection, making norovirus a predominant cause of foodborne illnesses in America.
The virus spreads through direct contact with infected individuals or by touching contaminated surfaces and then ingesting particles through mouth contact. The CDC estimates approximately 19 to 21 million cases annually, resulting in around 900 deaths and 109,000 hospitalizations primarily affecting older adults.
Symptoms and Recovery Period
Symptoms typically surface between 12 to 48 hours post-exposure and include diarrhea, vomiting, nausea, stomach pain, fever, headaches, and body aches. Dehydration can also occur due to symptoms such as decreased urination and dry mouth. While most individuals recover within three days of onset, they can remain contagious for several days thereafter.
Preventive Measures against Norovirus
To combat norovirus transmission effectively, consistent handwashing is crucial along with thorough cooking of shellfish before consumption and washing fruits and vegetables diligently. Additionally, disinfecting surfaces regularly and laundering clothes in hot water are recommended practices.
If afflicted by norovirus symptoms, it’s imperative to stay home for at least 48 hours post-symptom relief to prevent further spreading of the virus.
