This office has handled many cases of Legionnaires’ disease acquired from a spa, hot tub or Jacuzzi. The recent outbreak in Hampton, New Hampshire is a case in point. One possible source of this outbreak is in the indoor spa at the Sands Resort in Hampton. The reasons a spa may be a source is due to the nature of the system supplying water to the spa. The system itself is called a closed loop system. This means that the water supplying the spa, hot tub or Jacuzzi is in a continuous loop closed off from other water systems in the building. The potential for legionella buildup is obvious. The buildup will occur unless the water in the spa water system is properly filtered and treated. Different types of filters exist but they all have the same purpose, i.e. to filter out contaminants that could act as a host for the legionella bacteria to grow. The filter could also act as a source for the legionella to grow if the bacteria lodges in the filter itself. The other requirement to prevent legionella bacteria propagation in a spa, hot tub or Jacuzzi is the proper dosing of the water with a biocide such as bromine or chlorine which thereby kills the bacteria causing Legionnaires’ disease. Many cases handled by this office have been resolved because the property owner where the spa was located could not produce adequate records to show proper maintenance of the filter or adequate chlorine or bromine being added to the spa water. One case in Daytona Beach handled by this office included victims who acquired Legionnaires’ disease even though they did not physically go in the indoor spa but merely walked passed it when they were going to the room where breakfast was served each morning by the hotel.
