I am in my final days of the flu but someone in my household is still sick. will i be able to get the flu again?

Very unlikely: If it's the same virus, you should have created an immune response to it, that will protect you from this 'strain'. If, however, it's a different virus- then you may not be protected. Hopefully you're doing all the right things like RESTING, eating right (chicken soup is good), avoiding smoking or any toxic habits and giving your body what it needs to recover. Talk to your doc if you still have Qs
