Sadly parvo virus is resilient in the environment and can live for years. Where ever your previous puppy went to the bathroom is where it is most concentrated. If it is a hard surface such as concrete, you can bleach the area to kill the virus. In soil and grassy areas, it is impossible to get rid of it completely. If you get a new puppy, get them vaccinated every 2-3 weeks and keep them indoors to protect them. After 3-4 sets of vaccines, they should be protected enough to start going outside.
