A reaction-diffusion model that describe the dynamics of disease
transmission for a sexually transmitted disease with two competing
strains is introduced. Particular interest is given to the case
where the time delay is taken into account. It has been shown
that if there is an unstable coexistence endemic steady state,
then there is a unique bistable connection of traveling wave
solution. This matches well with the principle of competitive
exclusion.
