Norovirus Cases on the Rise in the US: What You Need to Know
Norovirus cases have been increasing in the United States over the past few weeks, according to data from the Centers for Disease Control and Prevention (CDC). The CDC reports that nearly 14% of tests for the illness came back positive during the week ending on November 15, with over 2,700 tests conducted, resulting in approximately 380 diagnosed cases.
This represents a significant increase from three months ago, when test positivity rates were at their lowest, with a 6.53% positivity rate from over 4,240 tests conducted during the week ending on August 9. While test positivity rates can vary based on the number of tests conducted, the CDC’s data provides valuable insights into the prevalence of norovirus and other diseases.
Understanding Norovirus
Norovirus, often referred to as the stomach bug or stomach flu, is the leading cause of vomiting and diarrhea in the United States, according to the CDC. It is also the leading cause of foodborne illness, resulting in millions of cases of illness each year. The virus is highly contagious and causes symptoms such as nausea, belly pain, vomiting, and diarrhea, which typically last between one to three days.
The CDC reports that norovirus results in over 100,000 hospitalizations and approximately 900 deaths per year, with adults 65 and older being the most likely to die from the illness. Young children and individuals with compromised immune systems are also at a higher risk for severe illness or death. Outbreaks of norovirus are most common between November and April, with a significant surge in cases typically occurring during the winter months.
Prevention and Precautions
To prevent the spread of norovirus, the CDC recommends frequent handwashing, safe handling and preparation of food, and regular cleaning of surfaces. It is essential to continue these precautions for at least two days after symptoms have ended, as the disease can still be contagious during this time. By taking these simple steps, individuals can significantly reduce the risk of contracting and spreading norovirus.
Recent outbreaks of norovirus have been reported in various settings, including a Michigan middle school, which was closed for a day for deep cleaning after dozens of students reported feeling ill, and a cruise ship, where nearly 100 passengers were sickened by the virus in October. These incidents highlight the importance of vigilance and prompt action in preventing the spread of norovirus.
