There are some antibacterial foods...don't know how they would help against certain bugs, but you never know...coconut, cranberries, garlic come to mind. Stock up. Especially cranberries since I am affiliated with them. There are essential oils used in aromatherapy that are mighty bacteria fighters...almost all are..and they are pretty cheap..orange, lemon. The most powerful are thyme and clove I think. Just put a few drops in water and spray. Tea tree oil is also anti=viral I believe. These are all things you would like anyway in housekeeping, air freshening etc. Some can be used in the bath (read up on which ones...some are too strong unless put in the right carrier oil in right proportions..) They are good for a lot of ailments besides. And orange cheers you up..especially mixed with nutmeg oil. mg
