joining us this morning, new york city health commissioner dr. mary bassett. and thank you very much, doctor, for joining us. so, is this the latest outbreak du jour? how serious is this? how worried should we be? >> well, here in new york city, we know that we have no zika transmission. all three cases that you virus by traveling to a place where we knew that zika was ongoing. but, yes, there has been an outbreak that has affected a growing number of countries in latin america and the caribbean. that's why travel advisories have been issued. >> so, what's the city doing? what's your concern as the top doctor here in new york city? >> yes, so, the first thing is to give advice to people who travel, everyone who travels to area where we know there's zika transmission -- and the number of places keeps growing. you need to check and see what the current status is -- should take precautions against mosquito bites, but our special concern is for pregnant women or women who are trying to get pregnant, because you don't always know the instant that you get pregnant.
