Legionella Testing Market Trends:

Rising Prevalence of Legionellosis

The rising incidences related to Legionellosis disease, which is a pneumonia-like illness, usually caused by a bacterium that varies in severity from mild to severe illness and sometimes fatal form of pneumonia, are propelling the market. For example, in September 2023, a total of 166 cases of legionellosis, including 23 deaths, were reported from Poland. Additionally, in May 2023, the Lithuanian National Public Health Center reported the investigation of an unexpected number of cases of Legionnaires’ disease in the Kaunas district of Lithuania, Europe. In line with this, Legionella bacteria was found in water samples from the buildings where the cases resided. Furthermore, the proliferation of Legionella-causing bacteria that are commonly found in several artificial and natural aquatic environments, such as respiratory therapy equipment, fountains, misting devices, cooling towers, spa pools, and water systems in hotels, homes, factories, etc., is also catalyzing the legionella testing market outlook. For instance, in July 2022, the Pennsylvania Department of Health received two reports of laboratory-confirmed Legionnaires disease in patients who received lung transplants from the same donor at a single Pennsylvania hospital. The donor’s cause of death was freshwater drowning in a river, raising suspicion of potential donor-derived transmission because Legionella bacteria naturally live in fresh water. As a result, health agencies in various countries are launching an effective water safety plan (WSP) to reduce the proliferation of Legionella in the water. Some of the common rules and regulations pertinent to the disease include the Surface Water Treatment Rule (SWTR) and the Safe Drinking Water Act (SDWA).

Various Technological Advancements

The increasing number of clinical trials on diagnostic and treatment strategies for patients with community-acquired pneumonia is strengthening the market. Key players in the healthcare industry are focusing on introducing novel molecular diagnostics and rapid test methods, as they offer more accurate and quicker testing outcomes, thereby improving the efficiency of legionella testing and control strategies. For example, in December 2023, one of the diversified biotechnology companies, CCM Biosciences (CCM Bio), launched its business unit, CCM 5Prime Sciences (5Prime), focused on the globally commercialized and multiple patent-protected compositions for next-generation DNA sequencing and molecular diagnostics. Apart from this, sensitive and rapid PCR-based methods are gaining immense traction as alternatives to the conventional culture system for the detection of slow-growing bacteria, such as Legionella spp. They use specific fluorescent probes that allow them to detect bacteria in water samples. Prominent brands, including Biopremier, offer simple, reliable, and rapid procedures, including real-time PCR detection test kits, to detect Legionella spp. Moreover, the widespread integration of technologies, such as artificial intelligence (AI), to identify and predict potential legionella outbreaks by analyzing data trends, including flow rates and water temperature, is elevating the legionella testing market share. For example, in May 2024, the Dubai Central Laboratory introduced a new artificial intelligence (AI) technology to seamlessly detect Legionella, a bacterium that causes acute respiratory infections.

Growing Regulatory Standards

Regulatory and government bodies across the globe are implementing stricter drinking water standards and regulations to control legionella outbreaks, especially in hotels, healthcare facilities, public buildings, etc. These regulations mandate regular risk and water testing assessments to ensure public safety, thereby escalating the demand for legionella testing services. For example, in April 2024, the U.S. Environmental Protection Agency (EPA) released the first-ever National Primary Drinking Water Regulation for certain per- and polyfluoroalkyl substances (PFAS), also known as ‘forever chemicals.’ Besides this, for drinking water, the World Health Organization (WHO) suggests that Legionella bacteria should be absent in water utilized for human consumption. Numerous guidelines, often set by local authorities or industry standards, indicate acceptable levels and testing protocols. They generally involve implementing measures and monitoring Legionella counts to ensure they remain below certain thresholds to reduce associated health risks. For instance, in the United States, the Centers for Disease Control and Prevention (CDC) provides guidance on Legionella testing and management for several water systems. Furthermore, other organizations, such as the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), provide recommendations for action levels related to this infection. Consequently, facility managers are taking corrective actions to protect the health of occupants. Some of the leaders in providing innovative solutions, including IWC Innovations, offer expertise in Legionella risk mitigation, focusing on investigation, detection, prevention, and remediation of the disease.
