  We consider a non-attractive three state contact process on $\mathbb Z$ and
prove that there exists a regime of survival as well as a regime of extinction.
In more detail, the process can be regarded as an infection process in a
dynamic environment, where non-infected sites are either healthy or passive.
Infected sites can recover only if they have a healthy site nearby, whereas
non-infected sites may become infected only if there is no healthy and at least
one infected site nearby. The transition probabilities are governed by a global
parameter $q$: for large $q$, the infection dies out, and for small enough $q$,
we observe its survival. The result is obtained by a coupling to a discrete
time Markov chain, using its drift properties in the respective regimes.
