The Centers for Disease Control and Control and Prevention found that, aside from childcare facilities, that 16,569 hotels, resorts and motels had the highest rate of closure due to serious code violations, mainly low disinfectant in the water to battle bacteria, about 15% or 1 in 6 hotel inspections.
Shigella and novovirus cause stomach and intestinal infections like gastroenteritis. Another microorganism found in pools is pseudomonas, which causes harmless but unsightly pustules on the skin.
To prevent closures or violations, hotel managers and staff should be using routine maintenance and sanitation, with frequent pool checks during high use when chlorine will get a work-out. Anyone, including a member of the hotel staff can check the pH level of the pool by using free test strips available from the Water Quality & Health Council (water levels should be within 7.2 to 7.8.)
