Right, so this is Amanda and the CMV is a really common virus, it's actually an abbreviation for Cytomegalovirus. And this is a really common infection, most people are going to have it at some point in their life, and they probably won't even know it. They will have very mild symptoms, or they'll have symptoms that are similar to a cold, flu like symptoms, and they'll think, well, I had a cold, I had the flu, and they'll never know that it really was CMV. But Congenital CMV is actually when an infant is infected with that virus before birth. So if someone is pregnant, and they, you know, they have CMV in their body, it can go to the baby through the placenta. And so that is what is called Congenital CMV. So anytime that a baby is born, having been exposed to the virus in utero, that is Congenital CMV. And it's important because, well, for several reasons. It's common. And we'll talk about that a little bit more. But you know, about one in every 200 babies are born with CMV. It can be serious, you know, babies can have significant symptoms. And some babies actually do die from the virus. Or some children have pretty severe disabilities and are medically complex. And maybe we'll have, you know, lifelong challenges, health problems, things like that. So that's why it's important.
