Olivia, My prayers for the babies.
Here's a link that tells how to clean the house and yard. It is so very contagious so make sure that everything that you take back home with you has been disenfected also, if you can. If my vet has a parvo case come in the tech and vets that treat the dog cannot go near another animal until they've showered and changed clothes and the areas where the infected pet has been is disenfected with bleach solution.
