Worse case scenario, bleach fumes can kill bacteria in the throat, nose, and mouth and cause a sore throat/bronchitis a couple of days after the inhalation. When the bacteria is repopulated, the sorness will go away. You won't die or anything, just be uncomfortable and in some pain. Water with fresh lemon juice will sooth the throat while it heals. Don't take antibiotics or you will lengthen the recovery time. If the inhalation wasn't too bad, nothing will occur. good luck
