Transcript for Almost Half the Nation Seeing High Flu Activity
both frigid weather and the flu. Flu has reached epidemic levels with half of the United States, 22 state, seeing high flu activity. At least 15 children have died so far and with kids now heading back to school tomorrow after the holiday break we wanted to were in Dr. Jeb bush Ashton for advice. Good morning. Good morning. So areal schools like petri dishes at this time. They always are. This year it's all about the strain of flu known as h3n2 what is hitting particularly hard especially kids and teenagers. But there are some things that we're doing even in my house with my kids as they get ready to go back to school that you can encourage your kids to do to help prevent or reduce the risk of getting sick. The CDC is still recommending the flu vaccine, even though it's not a particularly good match, it can offer some benefit. We always tell our kids, wash your hands, keep them clean. The more you wash them, the better. Getting a lot of sleep is definitely helpful. Covering sneezes or coughs with tissues and if they're not feeling well, keep them home from school. It's so important. It's not too late to get the flu shot. No, we still have four more months of the flu season. When we talk about the flu reaching epidemic levels, that's a bit of a scary term but doesn't it become an epidemic every year. Pretty much. This is really just a descriptive term that means they're seeing more cases either confirmed or flu-like illness than they would expect to see in a given population over a certain period of time. Now, if you look back to last year, the flu peaked around late December, we don't know yet what we're going to see because, again, we still have about four more months in the flu season but, again, we have to wait and see right now it's not looking too good. No, it's not so get that shot. Absolutely. Dr. Ashton, thank you very much.
