Just reading this article from 31st January:
"Health experts warn China travel ban will hinder coronavirus response."
"The Trump administration’s decision to ban most foreign nationals who had been to China in the last two weeks from travelling to the United States amid an accelerating outbreak of a novel coronavirus there was preceded by calls for similar policies from conservative lawmakers and far-right supporters of the president. Public health experts, however, warn that the move could do more harm than good."
"The administration’s public health emergency declaration also requires U.S. citizens returning from China to undergo some level of quarantine, depending on where they had been in China."
"Beyond Capitol Hill, Mike Cernovich, a prominent conspiracy theorist and early Trump supporter, had agitated on Twitter for a Chinese travel ban, as has Michael Savage, another conspiracy theorist and a radio host with white nationalist beliefs. “QUARANTINE! STOP TRAVELERS FROM CHINA NOW!” he said on Twitter last week."
"The ban comes on top of moves by major U.S. airlines halting flights to and from mainland China."
"Public health experts have warned that travel bans are not effective at stemming the spread of a virus and can make responding to an outbreak more challenging." ...
"The World Health Organization, which declared the outbreak a global health emergency this week, has recommended against any travel or trade restrictions in response to the outbreak. Member countries, however, do not have to comply with that guidance."
“Although travel restrictions may intuitively seem like the right thing to do, this is not something that WHO usually recommends,” said Tarik Jašarević, a WHO spokesperson.“This is because of the social disruption they cause and the intensive use of resources required,” he added."
