According to recent data from the U.S. Centers for Disease Control and Prevention, cases of a stomach bug known as norovirus have been on the rise in certain parts of the country this winter. In fact, the most recent numbers show that there were 91 reported outbreaks during the week of December 5th, which is a significant increase from the 69 outbreaks reported the previous week. This is also higher than the maximum of 65 outbreaks reported during the first week of December in the past few years.
Norovirus is a highly contagious infection that is characterized by sudden onset of vomiting and diarrhea. It is commonly seen on cruise ships, in places where people live closely together such as nursing homes and prisons, and in schools. It can be easily spread through direct contact or by consuming contaminated food or water.
So, what exactly is norovirus? According to the CDC, it is the leading cause of foodborne illness in the United States, responsible for 58% of such infections each year. It is caused by a group of viruses that are easily spread, with just 10 particles being enough to make someone sick. In the United States, there are about 2,500 reported outbreaks of norovirus annually, with the highest numbers occurring between November and April. Along with vomiting and diarrhea, other common symptoms include nausea, stomach pain, body aches, headache, and fever.
One of the main ways that norovirus outbreaks occur is through person-to-person contact, such as sharing food or utensils. It can also be spread through contaminated food, water, or surfaces. The illness typically starts very suddenly, with symptoms appearing 12 to 48 hours after exposure to the virus. Most people recover within a few days, but the virus can be serious for certain groups, such as older adults and those with weakened immune systems. In fact, on average, norovirus causes 900 deaths and 109,000 hospitalizations each year in the United States.
So, who is most at risk for norovirus? The answer is everyone. People of all ages can become infected and sick, but young children, older adults, and those with weakened immune systems are most at risk. Dehydration is a major concern for those who become ill, so it is important to seek medical help if you experience symptoms such as decreased urination, dry mouth and throat, or dizziness when standing. Rehydration is recommended by drinking water and other fluids, except for coffee, tea, and alcohol.
The best way to protect yourself against norovirus is through frequent and thorough handwashing. This is especially important during the peak winter season when the virus is most prevalent. It is recommended to scrub your hands with soap and warm water for at least 20 seconds before meals. Additionally, disinfecting surfaces in your home can also help prevent the spread of the virus. Taking these precautions can help keep you and your loved ones healthy during norovirus season.
