"Another is what precautions are required and followed in the place that you're going and then the third is what are you planning to do once you're there."Are you planning to visit a lot of attractions and go to indoor bars? That's very different from you're going somewhere where you're planning to lie on the beach all day and not interact with anyone else. That's very different. Those are very different levels of risk."Vaccination is the most significant safety factor for travel since unvaccinated travelers are more likely to become ill and transmit COVID-19 to others, Wen said.She said people should be wearing a high-quality mask 맥스카지노� N95, KN95 or KF94 맥스카지노� anytime they're in crowded indoor settings with people of unknown vaccination status.Before you travel, it's also important to consider what you would do if you end up testing positive away from home, Wen said. Where will you stay and how easy will it be to get a test to return home?
