China begins getting isolated

Since 31 December 2019, some regions and countries near China tightened their screening of selected travelers. The Centers for Disease Control and Prevention (CDC) of the United States later issued a Level 1 travel watch. Guidances and risk assessments were shortly posted by others including the European Centre for Disease Prevention and Control and Public Health England. In China, airports, railway stations and coach stations installed infrared thermometers. Travelers with a measured fever are taken to medical institutions after being registered and given masks. A real-time reverse transcription-polymerase Chain Reaction (RRT-PCR) test was used to confirm new cases of coronavirus infection.
