 The World Health Organization is in the meantime preaching against travel bans. The global body says the bans are causing challenges to the sharing of laboratory samples from South Africa that can help get better groups on the new variant. The comments were made at the first press briefing by the UN Health Agency since it christened Omicron as a variant of concern. So the idea that you can put a hermetic seal on most countries is just frankly not possible. We all know that. We've seen that happen before. And certainly there has to be consistency in that. If they are being applied, they have to be consistent. And certainly we've seen a lot of inconsistency with countries, for example, in Africa having banned travel and they haven't had a single confirmed case. And other countries with confirmed cases and evidence of local transmission with no travel bans. So I'm not saying one is right or one is wrong. What I'm saying is I can't see the logic, certainly from a public health or an epidemiologic perspective.
