Obama is implementing his one world/no borders ideology. His acolytes at CDC are more concerned with politically correct Obama approved protocols rather than policies that would protect the health and well being of the American people. There is no vaccine, no definitive treatment, no commercially available reliable diagnostic test ,and infected people can remain asymptomatic for up to three weeks. There is no medical rational to allow travelers to enter the United States. Screening is ineffective and quarantines are not being enforced.
