Jenny, I don't think you have to worry about bird flu now. I would be concerned about the annual influenza that we see every year. Be sure to get your flu shot. While immunity is usually in place in a couple of weeks, it takes a full 6 weeks to reach peak immunity. Being immunocompromised, I do not know how much immunity you will actually build. I do know that if someone is on immunosupresant drugs, such as Prednisone, and its a temporary therapy, then it is more prudent to wait until they are off of that so they can build the appropriate immunity. I would be sure that the children are immunized so that they don't get the flu and bring it home to you. Avoid the malls, grocery stores, etc on crowded days. Go shopping when most people are at work or at home. Take Purell in your purse so when you don't have a chance to wash your hands you can use Purell when you come in contact with door knobs, money, hand rails, etc.
