FORJAN LOZANO, Eduardo et al. Considerations on Updating the Spanish Legislation on Legionelosis. Ars Pharm [online]. 2016, vol.57, n.1, pp.11-22. ISSN 2340-9894.  https://dx.doi.org/10.30827/ars.v57i1.4381.

Objective: In Spain, Royal Decree 865/2003 establishes actions aimed at the prevention of legionellosis on the maintenance of systems related to the proliferation and transmission of the disease. This work aims to review certain structural, operational, of maintenance and documentary aspects which, from the point of view of Official Control, could be included in a future new legal regulation that might be more effective in preventing the emergence and proliferation of Legionella in the risk systems. Materials y Methods: To carry out this work Spanish legislation on Legionella, technical support documentation, other regulations from countries of EU and online services of scientific information (ISI Web of Knowledge) and databases of medical literature (MEDLINE PubMed) were used. Results and Discussion: After more a decade, it is necessary that certain technical aspects of risk systems in the transmission of legionellosis are reviewed and adapted to current knowledge and experience. These include the risk classification of the systems, technical and operational aspects of cold drinking and hot water systems, evaporative cooling equipment, spa pools and sampling procedures. Finally, the inclusion of molecular analytical techniques based qPCR as official methods in determining Legionella is discussed. Conclusions: A new legal regulation on the prevention and control of legionellosis should include a classification risk-based of the systems that collect emerging that have been associated with outbreaks. It must have annexes on preventive action to each of them, specific sampling procedures and models to assess appropriate risk that take into account sensitive establishments. Last it should be considered including molecular analytical techniques such as official or complementary methods. This update will allow a faster and more effective performance at identifying cases and associating them to risk systems.
