I suppose they didn’t want to admit that Belize can tell the USA no admittance, but the USA cannot not tell Liberia and the other countries fighting ebola “no travel to our country until the epidemic is contained.” Belize is apparently concerned with its public’s health and safety.
Better to err on the side of caution than to pooh pooh the whole thing and act an utter fool...which is what our government has done.
The authorities in Belize may be alarmist but their actions are understandable and far better than the actions of the US government IMO.
