WICHITA, Kan. (KSNW) – According to the Centers for Disease Control and Prevention (CDC), Norovirus leads to nearly 1 million pediatric medical visits each year. It is the leading cause of vomiting, diarrhea and stomach pain, with children particularly affected by it. "Unfortunately, it can cause a lot of upset, which can lead to vomiting and diarrhea. And it can be a pretty explosive amount. It can make someone very sick very quickly as they lose a lot of fluids and electrolytes," said Dr. Amy Seery, a pediatrician at Ascension Via Christi. But she tells parents to not panic. There are ways you can try to prevent the spread of Norovirus. "Really, aggressive hand-washing is the name of the game, and definitely don't want someone who is symptomatic necessarily participating in food preparation. Even with really good handwashing, the risk is definitely there," said Dr. Seery. Nasty norovirus is back in full force with US cases of the stomach virus surging These necessary measures are the priority for Bright Minds Learning Center in Wichita. "We have procedures that we follow for diaper changing, helping the older kids at the bathroom, and we followed those everything all day. And we wash hands constantly. We constantly sanitizing cleaning," said Donna Lee, the director of Bright Minds on 37th Street. The CDC says Norovirus cases are most common from November to April, and it can spread easily in daycare centers because of shared spaces and high-touch surfaces. "If we do get a case, we do let the parents know, hey, we have had this and that, this and discovered this virus. It goes for anything that we have. We do let the parents know so that they can also help us watch with their children if they get it. And that kind of helps prevent it," said Lee. And if your kid gets this virus, Dr. Seery says hydration is key. "If at any point you are seeing blood in your vomit or in your diarrhea, that's a good time to reach out to a medical team. And we might, in that instance, use a medication to calm down your system. But we're going to go right back to supportive care then, working on that hydration," she said.
