Ebola travel rules: who must sign the new US attestation form, what happened to the green card ban, and why WHO objects

Since late on November 3, everyone boarding a flight to the United States from abroad must sign a form saying they have not been in the Democratic Republic of the Congo in the past 21 days. It is the second layer of US Ebola rules. The first, an entry ban in place since May that also covered green card holders, expired on November 10, and no renewal had been published as of November 11. The World Health Organization advises against travel restrictions.
