The Impacts of Medical Resources on Emerging Self-Limiting Infectious Diseases

The spread of emerging self-limiting infectious diseases is closely related to medical resources. This paper introduces the concept of safe medical resources, i.e., the minimum medical resources that are needed to prevent the overburden of medical resources, and explores the impacts of medical resources on the spread of emerging self-limiting infectious diseases. The results showed that when the isolation rate of hospitalized patients who have mild infections is low, increasing the isolation rate of patients with severe infections requires safe more medical resources. On the contrary, when the isolation rate of hospitalized patients with mild infections is at a high level, increasing the isolation rate of patients with severe infections results in a decrease in safe medical resources. Furthermore, when the isolation rates of patients with mild and severe infections increase simultaneously, safe medical resources decrease gradually. That is to say, when the medical resources are at a low level, it is more necessary to improve the isolation rates of infected individuals so as to avoid the phenomenon of overburdened medical resources and control the spread of emerging infectious diseases. In addition, overwhelmed medical resources increase the number of deaths. Meanwhile, for different emerging self-limiting infectious diseases, as long as the recovery periods are the same, safe medical resources also remain the same.

Anesthesiology and Critical Care Response to COVID-19 in Resource-Limited Settings: Experiences from Nepal

It is difficult to predict the future course and length of the ongoing COVID-19 pandemic, which has devastated health care systems in low- and middle-income countries. Anesthesiology and critical care services are hard hit because many hospitals have stopped performing elective surgeries, staff and scarce hospital resources have been diverted to manage COVID-19 patients, and several makeshift COVID-19 units had to be set up. Intensive care units are overwhelmed with critically ill patients. In these difficult times, low- and middle-income countries need to improvise, perform indigenous research, adapt international guidelines to suit local needs, and target attainable clinical goals.
