## 4 Conclusions  
This paper studied the impacts of medical resources on emerging self-limiting infectious diseases and performed a numerical analysis using the SEIHR model. The results showed that for emerging self-limiting infectious diseases, ensuring a safe amount of medical resources could effectively deal with the outbreak of infectious diseases and reduce the number of deaths. When the isolation rate of hospitalized mildly infected individuals is small, the value for safe medical resources would increase with the increase in the isolation rate of hospitalized severely infected individuals. On the contrary, when the isolation rate of hospitalized mildly infected individuals is high, the value for safe medical resources would decrease with the increase in the isolation rate of hospitalized severely infected individuals. When the isolation rates of hospitalized severely infected individuals are at different levels, increasing the isolation rate of hospitalized mildly infected individuals would significantly reduce the value for safe medical resources.  
In conclusion, the isolation rates for hospitalized mildly and severely infected individuals should be increased, even with fewer medical resources. For the COVID-19 pandemic, the initial toxic strain has evolved into the faster spreading omicron strain. The protective effectiveness of the vaccines decreases over time. Most people are still at risk and many people who become infected have no symptoms but are still contagious. The results provided in this paper have a certain practical significance for guiding pandemic prevention and control measures. For example, the establishment of special isolation points and makeshift hospitals, the improvement in the frequency and scope of screening tests and the isolation of asymptomatic and mildly infected individuals could effectively control the spread of a pandemic and decrease the number of infected individuals, thus greatly reducing the risk of death among the elderly and children.  
In this paper, a differential equation model was established that was based on the compartment theory under the condition of a well-mixed population and the effects of isolation rates on medical resources was discussed in terms of the simulation results. The mathematical theories of the basic regeneration number, the stability of the disease-free equilibrium point and the local and global stability of the model could be further discussed. In addition, this paper only considered the spreading process of emerging self-limiting infectious diseases under different isolation rates of hospitalized mildly and severely infected individuals. Most of the parameters that were set in this paper were assumed values. Specific patient data and the protective effects of the vaccines, as well as the rules of transmission based on network transmission, were not involved, but would be worth further discussion.
