**Norovirus Cases on the Rise: What You Need to Know**

We're seeing an increase in cases of "winter vomiting disease," also known as norovirus, ahead of schedule this year. Here's a breakdown of the latest data and how you can protect yourself.

  • Norovirus cases are surging across the United States, with notable increases detected in Louisiana, Michigan, and Indiana.
  • The virus spreads easily through contaminated food, water, hands, and surfaces, and symptoms can appear within a short period.
  • Preventing infection from norovirus includes proper handwashing, disinfecting surfaces, avoiding close contact with others when sick, and staying home and hydrated if you become ill.

The Centers for Disease Control and Prevention (CDC) have reported 153 norovirus outbreaks from August to mid-November, which is considered ahead of schedule for the season. While this increase may be concerning, it's worth noting that norovirus outbreak trends are currently lower than last year.

Why is Norovirus Cases Rising?

The time of year plays a significant role in the current surge in norovirus cases. "Norovirus usually increases during the cold months when individuals have more indoor time and are in proximity to each other," says Dr. Blen Tesfu, physician and medical advisor at Welzo.

  • Holiday travel and an increase in social gatherings can contribute to the spread of norovirus.
  • Cold weather can weaken our immune system, making it easier for viruses like norovirus to spread.

What is Norovirus?

Norovirus infection may lead to symptoms of vomiting and diarrhea, as the virus primarily affects the gut. Unlike the flu, norovirus targets the gut, causing a viral gastroenteritis.

We want to emphasize that preventing norovirus infection is crucial during this time. Make sure to practice good hygiene, avoid close contact with others when sick, and stay home and hydrated if you become ill.
