I side with the caution taken by the person with HIV. I have diabetes and am also in the category of those aware of excess colds, flu and especially food bourne illnesses. Many are not aware that 50% of "stomach flu" is contracted within the home and a direct result of ingestion of a family members contaminated waste materials (such as in the toilet mist/spray/aerosol contamination that is caused by flushing).

Sounds disgusting but it's true. Research it yourself. Being diabetic opened my eyes to alot of potential life threatening "germs" and infections. Make that another fan of the germ filtering toilet guy.
