1. Purchase some SWISS probiotics /35billion/capsule and take one in the am and on in the pm with food per day
2. Purchase one whole hormone free chicken and cook (whole) in a large pot on low heat for 10 hours. You may throw away the meat if it's too tough for you by then (or you may take it off the bone after about 2 hours) and continue simmering the rest for 8 hours more. It's the broth that you're really after here, with plenty of lemon juice added, as these two will really boost your weakened immune system and get you back on track better than you were before your illness.
3. No need for any structured program for the 1st week back into training. Your mind can do with less stress at this point in time, with full focus on doing what you enjoy lifting the most, with reps of no less than 15-20, as these would see to it that your muscles as well as your connective tissues are flooded with nutrients filled blood, from all the heavy duty electrolytes and the amino acid glycine coming from that chicken broth you've stored in the fridge.
4. After the above week has passed, it would be your mind and body who'd be urging you to get back into it, as now you would have been thoroughly regenerated /recharged both physically and mentally.
All the best to you sir.
