Preventive Measurement against COVID‑19 Spreading: Immigration Cessation, Office Closing, and Holiday Postponement—Simulation Analysis

Worldwide spreading of coronavirus disease (COVID‑19) becomes an emergency problem globally. The control of disease needs good policy planning and the policies have to be properly adjusted to contexts in each setting. How to cut the chain of COVID‑19 progression is a common question in disease control management. Several preventive measurements are proposed and might be applicable. Indeed, it is necessary to use systematic evaluation to appraise the efficacy of alternative preventive options for disease prevention and control.[1] The common preventive measurements for COVID‑19 include immigration cessation, office closing, and holiday postponement.[2,3] Immigration cessation is the blockage of international connections that might be useful for controlling imported COVID‑19 disease. If this method is selected before there is any emerged case in the country, it will be the most effective technique. Office closing, including school closing, is the method to control the public place that might be the common spreading place when the disease already occurs and locally spreads. Holiday postponement is another option that is based on the concept to prevent mass population movement within the country that might mean carrying disease from the big city to rural towns.
