  This paper analyses an SIRS-type model for infectious diseases with account
for behavioural changes associated with the simultaneous spread of awareness in
the population. Two types of awareness are included into the model: private
awareness associated with direct contacts between unaware and aware
populations, and public information campaign. Stability analysis of different
steady states in the model provides information about potential spread of
disease in a population, and well as about how the disease dynamics is affected
by the two types of awareness. Numerical simulations are performed to
illustrate the behaviour of the system in different dynamical regimes.
