Does a dog with parvo stay sick for the entire week?

i have a 3 month old dauchsund puppy and i just found out friday april 29th that she sick since my mother watches her while im at work. i brought her to the emergency vet saturday april 30th and they tested her for parvo it came back positive and she was given liquids through an IV i picked her up that following monday at 7 am and brought her to her regular vet the quack wanted to charge a 1000 dollars to treat and i couldnt afford so im treating her from home. shes been acting totally fine. drinking and eating. ive been giving her chicken broth, pedilyte, soft dog food and water. shes been showing no signs of being sick and was wondering if the virus was over? or is she gonna get sick again
