According to recent data, the number of individuals falling ill with norovirus, also known as the "winter vomiting bug," has risen significantly compared to previous years. This highly contagious virus, which can also cause diarrhea, is currently at almost double the usual level for this time of year. This concerning increase is largely due to a new strain of the virus, affectionately nicknamed "Kawasaki" after its initial discovery in Kawasaki, Japan. In fact, this new variant is responsible for nearly 90% of all norovirus cases.
While this new strain is not believed to cause more severe symptoms than previous outbreaks, it is highly contagious, making it easier to spread from person to person. Dr. John Burke, the chief medical officer at AXA Health, explains, "Norovirus is an extremely infectious virus that is transmitted through contact and can result in sickness and diarrhea for those who contract it. As we spend more time indoors during the autumn and winter months, cases of norovirus tend to skyrocket due to close proximity with others."
The virus can be easily spread through contact with an infected individual or contaminated surfaces. Although most people recover within two or three days, the virus can lead to dehydration, especially for vulnerable populations such as young children, the elderly, and those with weakened immune systems. Some of the most common symptoms of norovirus include nausea, vomiting, diarrhea, high temperature, headaches, and exhaustion.
If you do become infected with norovirus, it is crucial to avoid contact with others for at least 48 hours after your symptoms have subsided. This is essential in reducing the spread of the virus, which is responsible for approximately 12,000 hospital admissions in the UK each year. As Dr. Burke, a GP with 25 years of experience, advises, "It is important to stick to bland foods while recovering from norovirus to avoid further upsetting your stomach. If you are having trouble keeping food down, try small amounts of easily digestible options such as toast and crackers. Furthermore, it is crucial to stay well-hydrated, as the body loses a lot of fluids through vomiting and diarrhea. Make sure to regularly drink clear fluids and electrolytes to prevent dehydration."
It's also important to note that rest is vital for a speedy recovery from norovirus. As Dr. Burke explains, "Give your body adequate time to rest and recuperate from the virus before returning to your normal routine." Unfortunately, the number of norovirus cases is on the rise, with recent data from the UK Health Security Agency showing a significant increase compared to five years ago. Amy Douglas, an epidemiologist at UKHSA, explains, "The recent half-term school break may have temporarily slowed the upward trend in norovirus cases, but we can expect to see numbers rise again as we approach the holiday season."
If you do experience symptoms of norovirus, it's essential to take precautions to avoid spreading the virus to others. This includes avoiding work, school, or other public places for at least 48 hours after your symptoms have stopped. Additionally, refrain from preparing food for others during this time and avoid visiting hospitals or care homes to prevent infecting vulnerable individuals. Regular handwashing with soap and warm water, as well as using bleach-based products to clean surfaces, can also help prevent the spread of the virus. Remember, alcohol gels do not kill norovirus, so it's important not to rely on them as the sole means of protection.
