The bather is exposed to these microorganisms by inhalation, ingestion (often the case in children), and direct contact with broken skin. These bacteria cause 30-35% of all septicemias (blood infections), >70% of urinary tract infections, and many intestinal infectionsPseudomonas aeruginosa has been implicated in infections of the respiratory tract, burn wounds, urinary tract, ear, and eye. It can also cause bacterium, endocarditic, and gastroenteritisLegionella is the causative agent of Legionnaire's disease (with a 20% mortality rate) and Pontiac fever. Staphylococcus aurous causes a number of coetaneous infections including impetigo, folliculate, furuncles, carbuncles, and wound infections1 In the past, people have used chlorine bleach, vinegar, baking soda, or detergent to sanitize their pipes, whirlpools, and spas; however, these solutions do not sanitize the tubs.
