Exactly. I'm not convinced that stopping flights to/from West Africa will be at all effective - unless EVERY airline does it.
Of course it should be done with all airlines. Who suggested otherwise? It isn't hard. As I noted above, it's been done by this president within the last year and for something far less grave to American lives.
Going by passport might be more effective, but would still have issues.
I understand that 'perfect is not the enemy of good' but I'm also concerned about actions that create a false sense of security. Like PPE.
False sense of security? Eliminating the most likely vector of infection is good medical advice. It doesn't eliminate all risk.
