Borders are important because you can provide to people arriving from areas that might be at risk of having had infection, provide them with an understanding, either a printed understanding or a verbal understanding, of what the signs and symptoms are of this infection, and what they should do if they feel that they might be infected.
As fronteiras son importantes porque podes axudar á xente que vén de áreas en risco de ter a infección proporcionándolle información, xa sexa de forma impresa ou verbalmente, sobre cales son os indicios e síntomas da infección e sobre que deberían facer se cren que poden estar infectados.
