It's already inside the country and spreading through community contamination (spread inside the borders).

Some medic reports (my wife is a nurse, so she gets more detailed information) are expecting an increase to 45k cases on the next 4 months on São Paulo only.

Altough it spreads fast (that is why isolation is needed), the lethality isn't all that high on average, but the problem lies on people with a low immunity system (like elders and childrens).
