christian. dr. fauci, there s zero case of covid, omicron case in zimbabwe, in mozambique. what justified imposing a travel ban on countries that have zero case of the omicron variant? you know, that s a very good question and important question and we did struggle with that. but we wanted to see if we can buy time temporarily. so i do hope that this gets sorted out and lifted before it has any significant impact on your country. last week, the governor of new york signed an executive order to postpone elective opt surgeries to prepare for the omicron variant. i know you and your team are being proactive as we try to learn more about this, but do you believe some states might be going too far too quickly before we know too much?
