January 31. Trump action on infected foreigners: Proclamation on Suspension of Entry as Immigrants and Nonimmigrants of Persons who Pose a Risk of Transmitting 2019 Novel Coronavirus.
During Fiscal Year 2019, an average of more than 14,000 people traveled to the United States from China each day, via both direct and indirect flights. The United States Government is unable to effectively evaluate and monitor all of the travelers continuing to arrive from China. The potential for widespread transmission of the virus by infected individuals seeking to enter the United States threatens the security of our transportation system and infrastructure and the national security. Given the importance of protecting persons within the United States from the threat of this harmful communicable disease, I have determined that it is in the interests of the United States to take action to restrict and suspend the entry into the United States, as immigrants or nonimmigrants, of all aliens who were physically present within the People’s Republic of China, excluding the Special Administrative Regions of Hong Kong and Macau, during the 14-day period preceding their entry or attempted entry into the United States. I have also determined that the United States should take all necessary and appropriate measures to facilitate orderly medical screening and, where appropriate, quarantine of persons allowed to enter the United States who may have been exposed to this virus.
