BACKGROUND
Since the outbreak of coronavirus disease (COVID-19), a country’s ability to control the epidemic depends on how well its health system accommodates COVID-19 patients.
OBJECTIVE
The aim of this study was to assess the ability of different countries to contain the COVID-19 epidemic in real-time with the number of confirmed, death and recovered cases.
METHODS
Using the dataset provided by the Humanitarian Data Exchange (HDX), we compared the data from 16 countries between 2020/01/22 to 2020/09/15. We analyze the spreading of the virus using Little’s Law to predict a country’s ability for epidemic control.
RESULTS
According to the changes in the average recovery time curve, 16 countries are divided into different cases – Outbreak, Under Control, Second Wave of Outbreak, and Premature Lockdown Lift. Analyzing the dataset with Little’s Law, the curves of some countries (i.e., U.S., Spain, Netherlands, Serbia, France, Sweden, and Belgium) showed an upward trend representing their medical systems in these countries have been overloaded and unable to provide effective medical services to patients, i.e., those countries have lost control (i.e., Outbreak case) of COVID-19. On the other hand, after the pandemic-prevention policy was applied in some countries (i.e., Iceland, New Zealand, Taiwan, Thailand, and Singapore), the average recovery time dropped with the number of new cases decreased (i.e., Under Control case). The prevention policy, e.g., lockdown and gathering restrictions, shows the effect after 14 days, which is the same as the incubation period of COVID-19. The result shows that the average recovery time (T) can be used as an indicator of the ability of a country on controlling the pandemic.
CONCLUSIONS
In this paper, we use Little’s Law to estimate the capacity of each country’s healthcare system for the COVID-19 pandemic and find out a new estimator to represent the severity of the pandemic. We study the impact of interventions on the average recovery time in some countries. The result shows that the average recovery time (T) can be used as an indicator of the ability on controlling the pandemic.
