Pneumonia is the most important cause of child death in Thailand. Media is the power source in the knowledge transfer and dissemination process. This study explores the effect of awareness programs by media on the transmission model of pneumonia in Thailand. This dynamical model is analyzed using a standard dynamical modeling method. The stability of the model was determined by using Routh-Hurwitz criteria. In this paper, the disease free and endemic states have been found. To determine the basic reproductive number  which is the threshold parameter, if  then the disease free equilibrium point is locally asymptotically stable. The result shows that the awareness programs by media significantly cause the reduction in transmission and infection of pneumonia in Thailand. So, the media may be another option to prevent and control the disease.
