Sorry for these losses @Sweetened. I know it's tough to take. Don't be too hard on yourself. It is what it is. There are lots of diseases out there that kill quickly. Especially with newborns and the young (& old). Now that you've identified the cause, all you can do is try to protect the rest of your animals as best you can. And being able to share this/your experience with someone else down the road just might save them the same heartache you're going through. Just sayin'
