yeap,
let's hope that the cases brought out of mexico stay mild.
in case of the masks,
yes, they are recommended to protect others to get infected by the person which is wearing the mask, but even not beeing a doctor, if somebody infected who does not wear a mask is sneezing near/in front of me a mask on my own face would also protect myself to inhale what is flying throu the air at that moment. of course there are other possibilities to get it like the ears, over your hands on a bathroom facility aso aso, to stay 10% save we would need to stay at home, not open the door, don't do shopping aso aso. at least at crowded places like an airport/airplane/train/subway aso hand sanitizers and a mask the best/only protection we can use.
of course i know that you woulod not be allowed to enter a bank over there with a mask over your face, you would get shot to do so here on the Island, that's kidding around and has nothing to do with a serious theme.
when entering customs at a airport, any airport, sure that officer wanna see your face without a mask, and i guess he will not zneeze in your face while you lift it up, in a responsible country that customs officer should be wearing a mask to check people's face and compare it with their passportfoto, but while you stay in line of that customs desk and afterwards while you are at the crowded spot to await your luggage coming in a mask could not do any bad to you, even that it sure will not be a 100% allaround protection, but we should use the lil bit of protection available.
