Yes we have to take care, but not to scared.
Swine flu is like the normal flu that we get all the year.. but the problem is that in the beginning they didn't realise this, and that's why people got scared.

Calm down and be sure that what so ever allah planned to happen to us.. it will happen.. so don't be so scared.

May God be with us all.
