霍乱是一种严重威胁人类健康的疾病，其控制是一个备受关注的问题。在此背景下，提出了一个控制霍乱流行的非线性数学模型，并将电视和社交媒体广告作为动态变量进行了分析。据认为，电视和社交媒体广告向人们宣传了霍乱对人类健康的严重影响沿着预防措施。人们还假定，霍乱病在易感人群中的传播方式是由于饮用了含有霍乱弧菌的受污染饮用水。此外，通过电视和社交媒体广告传播的知识使人们意识到采取预防措施，并且意识到人们也做出了一些有效的努力来清除水环境中的细菌。模型分析表明，由于有意识的个人的细菌的洗脱率的增加，导致稳定性切换。研究发现，电视和社交媒体广告有可能减少该地区的感染者数量，从而控制霍乱疫情。数值模拟进行了一组特定的参数值，以支持分析结果。
Cholera is a serious threat to the health of human-kind all over the world and its control is a problem of great concern. In this context, a nonlinear mathematical model to control the prevalence of cholera disease is proposed and analyzed by incorporating TV and social media advertisements as a dynamic variable. It is considered that TV and social media ads propagate the knowledge among the people regarding the severe effects of cholera disease on human health along with its precautionary measures. It is also assumed that the mode of transmission of cholera disease among susceptible individuals is due to consumption of contaminated drinking water containing itVibrio cholerae. Moreover, the propagation of knowledge through TV and social media ads makes the people aware to adopt precautionary measures and also the aware people make some effectual efforts to washout the bacteria from the aquatic environment. Model analysis reveals that increase in the washout rate of bacteria due to aware individuals causes the stability switch. It is found that TV and social media ads have the potential to reduce the number of infectives in the region and thus control the cholera epidemic. Numerical simulation is performed for a particular set of parameter values to support the analytical findings.
