“…Chlamydia trachomatis and gonorrhea co-dynamics models with optimum control analysis have been studied and examined to assess the impact of targeted treatment for each of the diseases on their co-infections in a population [11]. Mathematical modeling and study of the transmission dynamics of blinding trachoma with the impact of awareness programs and found a lack of competent health care systems and public awareness programs to blame for the outbreak of the blinding trachoma disease [12]. A sophisticated investigation of Chlamydia trachomatis infection sensitivity was performed using a susceptible-exposed-infected-recovered-susceptible (SEIRS) model, and they also analyzed the population turnover and the impact of screening [13].…”

Aim: Sexually transmitted diseases (STDs) need to be studied systematically to better understand their global spread. Transmission of Chlamydia trachomatis is a severe public health issue, with roughly 90 million new cases per year. Globally, Chlamydia trachomatis is the most frequent bacterial cause of STDs. Methods: To better understand the dynamics and transmission of Chlamydia, the susceptible-exposed-infected-recovered-susceptible (SEIRS) model was constructed. Using a system of nonlinear ordinary differential equations, a basic reproduction number has been calculated at an equilibrium point, and the system is locally and globally asymptotically stable at both disease-free and endemic equilibrium points. Numerical simulations illustrate the behavior and flow of Chlamydia infections in different compartments. Results: Conclude from the proposed study that 25% of individuals have been exposed to Chlamydia, of which 20% of individuals get infections due to sexual activity and 55% of individuals get recovered. 20% of individuals have been exposed to Chlamydia, of which 37% of individuals have been infected due to an unhygienic environment. Of those, 43% of individuals recovered. Also, it has been found that people are more likely to get infections because of an unhygienic environment than sexually active people. The recovery rate is also much better for people who have been infected because of an unhygienic environment. Conclusions: Sexually transmitted infections can be reduced by up to 10%. While infection due to an unhygienic environment can be controlled up to a certain intensity. According to this research, public awareness campaigns and the improvement of personal hygiene will play a major role in reducing the spread of the epidemic in the future.

“…In addition, the awareness of infection among infected individuals plays a key role in the spread of slowly progressive diseases. Many researchers focused on studying the roles of the public awareness among susceptible individuals in the spreading of diseases, and showed that raising awareness of protection among susceptible individuals can effectively contain epidemic spread [17][18][19][20][21]. However, to examine the effects of the infection awareness among infected individuals on the epidemic theoretically is still a great challenge.…”

Contact tracing is an important tool to contain the spread of many airborne diseases. We develop an approximated pairwise model to investigate the impact of non-Markovian awareness process among infectious individuals represented by pairwise endemic models. We derive the basic reproduction number and the final epidemic size, which are dependent on the tracing rate and the distribution of awareness process. The model analysis provides the threshold of contact tracing rate. When the contact tracing rate is greater than the threshold, the basic reproduction number will be less than one, then the epidemic will eventually die out. The analysis further shows that, higher variance in the awareness process generates smaller basic reproduction number, lower tracing threshold, and larger final epidemic size, when the mean awareness period is fixed. Extensive numerical analysis show the comprehensive effects of tracing rates and non-Markovian awareness processes on human behavior and the transmissibility ability of epidemic. It turns out that large tracing rates and high variances in awareness process lead to obvious reductions in contacts between susceptible and infectious individuals, so as to curb the transmission of infectious diseases. Moreover, contact tracing is more effective in reducing the number of infected individuals and the contacts between susceptible and infected individuals when the awareness process has a larger variance.
