All very comforting, but we haven't heard of any cases in Mexico - does anyone believe that Mexico is 100% clean of it and that none will make it across the border?
When it lands in Mexico it will hit a developing country, not a third world primitive country. There will be hazmat teams taking victims to isolation wards. Those won't be perfect (ours were far from perfect as well) and there will be secondary infections. a few tertiary cases may not make the news, perhaps covered up by corrupt officials. But for the most part we will know about it and probably send some experts to help out.
One worry from Mexico is terrorists with biological weapons. But even a halfway smart terrorist would carry infected materials posing as one of the 150 refugees coming in each day. The terrorist would take great care not to get infected and potentially blow his chances of getting in. The materials would be in checked luggage and difficult to scan for (but how difficult I have no idea)
I doubt it’ll hit Mexico. It’s just not really a destination for 3rd worlders. You just never hear people saying “things are awful here, we should flee to a country that’s slightly less awful”. Nobody really trades warlords for drug lords. Anybody hitting Mexico in this is trying to get here, so they won’t be there long.
