Norovirus Symptoms: Is it Stomach Flu?
So once the virus gets in, what happens next? The virus begins to multiply and then you start getting symptoms. If you have ever had the ‘stomach flu’ you know how miserable it can be.
Symptoms come on suddenly, usually within 12 to 48 hours after you’ve been exposed to the norovirus, and include: diarrhea, vomiting, nausea, and stomach cramps. There are other symptoms, such as a low fever, chills, headaches, fatigue and muscle aches, but they’re uncommon. Generally most people recover in a day or two without any serious side effects, but remember – you’re still contagious even after you feel better!
Norovirus Infection: Shedding the Virus
You start shedding the virus once it has worked its way into your cells. If you’re sick with the norovirus, you can shed billions of virus particles, but it only takes as few as 18 particles to infect someone, according to the CDC.
Although it is possible for you to shed this virus before you start to feel sick, generally shedding occurs once you have the symptoms and for two weeks or more after you feel better. This doesn’t mean that you are still contagious; the CDC reports that it is unclear whether or not norovirus sufferers are still contagious long after they have recovered.
Although there’s a norovirus vaccine in the works, there’s no antiviral treatment for the stomach flu, so your only option for avoiding this nasty virus is to prevent it. Practice good hand hygiene; wash your hands frequently and with soap and water. You can use hand sanitizer if clean water and soap are not available.
When cleaning up after someone who is sick; know that Clorox or Lysol Wipes may not kill the norovirus. To kill the norovirus you should use a bleach and water solution to wipe everything down. To make the bleach solution, use anywhere from 5 tablespoons to one and half cups of bleach to one gallon of water. You should also wash any clothes, sheets, or towels that may have come in contact with bodily fluids during your bout with illness.
Gastroenteritis or Stomach Flu or Norovirus
This year’s ‘GII.4 Sydney’ stomach flu is hitting hard, but by any name, the norovirus contributes to 70,000 hospitalizations and 800 deaths every year. These hospitalizations and deaths mainly occur in young children and the elderly, but norovirus symptoms can make for a miserable couple of days for anyone, so your best option is prevention. One of the worst aspects of the stomach flu virus (other than that it doesn’t have a cure) is that there are so many different types of these viruses that, even after you get it once, you can still get sick again with another strain.
