“…Also, respondents who still use their hands to cover their nose and mouth when coughing or sneezing were urged to do the correct CTPS as soon as possible. It was explained that the effect of not closing the nose-mouth when coughing will spread airborne diseases such as common cold 15 . But the activities did not appear to show there was a good promotional effort.…”

Background: Cough cases are increasing every year. The most common cause is a virus. Coughing is influenced by endurance, Cough Ethics, and Handwashing with Soap/Cuci Tangan Pakai Sabun (CTPS). Transmission occurs through droplets in the air from the patient when coughing or sneezing. We need to educate the community to minimize transmission, especially among children. Ultimately, this speeds up the healing process. Objective: This study aimed to provide an understanding of Cough Ethics and behavior change using narrative in action to kindergarten teachers. Method: This study used descriptive-analytic qualitative methods with narrative in action. The subjects of the study were a population of kindergarten teachers in the working area of the Puskesmas Sedayu 1, selected purposive snowball sampling. Retrieval of data was done through the observation stage, pre-narrative in action activities, the narrative in action, post narrative in action activities, and the final observation stage in kindergarten. Result: Observations were done at the school to find out the infrastructure. Observation before and after the demonstration showed there were improvements and concluded that all can demonstrate the Cough Ethics and CTPS. Watching the Cough Ethics video, CTPS, followed by the dialogue, motivation, education, persuasion, promotion were empowering for the teachers to change their behavior. All groups when coughing or sneezing covered their nose and mouth with a tissue, mask, or the inner side of elbow arm or expelled phlegm on the ground, lodong/special place like a jar, and toilet. Conclusion: Narrative in action activities are an alternative way of providing understanding to change behavior. Watching videos makes it easy to explain the Ethics of Cough. Practice is needed to improve the skills of narrative in action.

“…It has been observed that half of the episodes of human illness are caused by respiratory viruses, i.e. by droplet infection as well as through direct contact [1]. Most of these are of course quite trivial infections like the common cold.…”

“…The virus may also be present in the urine, feces and on the skin of infected individuals. The common cold virus is transmitted mainly from contact with the saliva or nasal secretions of an infected individual, either directly, in aerosol form generated by coughing and sneezing or from contaminated surfaces [1]. There are many questions on the spread of an infectious disease, for example, how many people will be affected altogether and so need treatment.…”

“…Mathematical models are becoming important tools in analyzing the spread and control of infectious diseases. Epidemic models of ordinary differential equations have been studied by a number of researchers [1,[36][37][38][39][40][41][42][43][44][45][46]. The basic and important objectives for these models are the existence of the threshold values which distinguish whether the infectious disease will be going to extinct, the local and global stability of the disease-free equilibrium and the endemic equilibrium, the existence of periodic solutions and the persistence of the disease.…”

In this paper, we have considered a dynamical model of diseases that spread by droplet infection and also through direct contact. It is assumed that there is a time lag due to incubation period of pathogens, i.e. the development of an infection from the time the pathogen enters the body until signs or symptoms first appear. Pulse vaccination is an effective and important strategy for the elimination of infectious diseases and so we have analyzed this model with pulse vaccination and saturation incidence rate. We have defined two positive numbers R 1 and R 2 . It is proved that there exists an infection-free periodic solution which is globally attractive if R 1 < 1 and the disease is permanent if R 2 > 1. The important mathematical findings for the dynamical behaviour of the model are also numerically verified using MAT-LAB. Finally epidemiological implications of our analytical findings are addressed critically.

“…Alexander, Moghadas, Rohani, and Summers (2006), Anderson and Grenfell (1986), Dietz (1981), Misra and Mishra (2009) and Paulo, Gomes, Casinhas, and Horta (2000) studied the impact of multiple dose vaccination programme on the dynamics of infectious diseases. Recently, Samanta (2011) has proposed and analysed a nonautonomous dynamical model of diseases that spread by droplet infection and also through direct contact with varying total population size and distributed time delay to become infectious.…”

In this paper, we have considered a dynamical model of diseases that spread by droplet infection and also through direct contact with varying total population size and discrete time delay to become infectious. It is assumed that there is a latent period of the disease and an immune period of the recovered individuals. Pulse vaccination is an effective and important strategy for the elimination of infectious diseases and so we have analysed this model with pulse vaccination and saturation incidence rate. It is also assumed that the time lag due to lose of immunity of recovered individuals is equal to the interval between two pulses. We have defined two positive numbers R 1 and R 2. It is proved that there exists an infection-free periodic solution which is globally attractive if R 1 < 1 and the disease is permanent if R 2 > 1. The important mathematical findings for the dynamical behaviour of the model are also numerically verified using MATLAB. Finally epidemiological implications of our analytical findings are addressed critically.
