A boy died of swine flu in our locality!! What preventive measures can I take for my family?

My baby is 3 and half month old. A 4 year old boy died of swine flu in our locality yesterday. I feel for the boy and his family. I want to protect my baby and family from the disease, more so as I already know that virus is somewhere in the neighbourhood!!! (Its really scary). I have completely stopped going out with my baby. My husband gets all the grocery and supplies from outside and never touches the baby without washing his hands and feet. What else can we do to keep this virus at bay?
