Abstract: A renewal contact process is a (non Markov) process similar to the classical contact process
but where the rate one Poisson processes governing "recovery" are replaced by renewal processes
(transmissions are still modelled by rate lambda Poisson processes). We show that the critical values
are zero if the renewal distribution has very heavy tails but is strictly positive if a moment higher than
one exists (under some strict regularity condition).
