Before boarding their flights, all international passengers headed to the United States will first need to show proof of a negative coronavirus test, according to a new federal policy going into effect on Jan. 26. “Testing does not eliminate all risk,” Dr. Robert R. Redfield, the director of the Centers for Disease Control and Prevention, said in a statement describing the new policy.“But when combined with a period of staying at home and everyday precautions like wearing masks and social distancing, it can make travel safer, healthier, and more responsible by reducing spread on planes, in airports, and at destinations.”Dr. Redfield is expected to sign the order detailing the new rules on Tuesday. The new policy requires all air passengers, regardless of vaccination status, to get a test for current infection within the three days before their flight to the United States departs, and to provide written documentation of their test results or proof of having recovered from Covid-19.Proof of immunization will not be sufficient, because the vaccines have only been shown to prevent serious illness, said Jason McDonald, a spokesman for the C.D.C. Vaccinated people may still become infected, in theory, and transmit the virus on a flight.
The agency will not require further testing in the three months after a positive test, so long as the traveler has not had any symptoms. In this situation, a passenger may travel with documentation of the positive test result and a letter from a health care provider or a public health official stating that the traveler now has been cleared for travel.

]]>J’aimerais vraiment qu’il y ait des discussions sur les problèmes éthiques et médicaux que soulèvent ces « certificats d’immunité ». Je trouve que les problèmes sont encore plus inévitables, et peut-être aussi graves, que l’usage du tracking, mais je n’ai pas vu passer de discussions à ce sujet.
Parce que si on part là-dedans sans s’interroger sur les implications, Helmut Marko pourra être considéré comme un précurseur :

The temple was two hundred and fifty years old, the attendant informed me. That would date it to around the time when accounts first appeared of a mysterious sect of Brahmans wandering up and down the Gangetic plain to popularize the practice of tika, an early effort at #inoculation. This involved taking matter from a smallpox patient’s pustule—a snake pit of live virus—and applying it to the pricked skin of an uninfected person, then covering the spot with a linen rag.
The Indian practitioners of tika had likely learned it from Arabic physicians, who had learned it from the Chinese. As early as 1100, medical healers in China had realized that those who survived smallpox did not catch the illness again (survivors of the disease were enlisted to take care of new victims), and inferred that the exposure of the body to an illness protected it from future instances of that illness.
