KEY MARKET INSIGHTS

Play Audio Listen to Audio Version

The global legionella testing market size was valued at USD 317.3 million in 2023 and is projected to grow from USD 346.8 million in 2024 to USD 726.3 million by 2032, exhibiting a CAGR of 9.7% during the forecast period (2024-2032). North America dominated the global market with a share of 39.71% in 2023.


The global market is predicted to experience significant growth due to the increasing prevalence of Legionnaire's disease, Pontiac fever, and pneumonia. Moreover, the growing awareness about sanitation and a heightened emphasis on preventing infectious diseases are expected to boost the demand for Legionella testing kits. Legionella is a bacterial species that predominantly thrives in freshwater sources such as showers, bathtubs, ponds, swimming pools, and other water sources. Stringent regulations were established for the regular testing of freshwater sources, especially after the prevalence of Legionella infection in the U.S. in 1997. The rising occurrence of the disease is anticipated to drive the growth of the global market.



  • For instance, according to the World Health Organization (WHO) 2022 data, in the U.S., Europe, and Australia, about 10-15 cases are detected per million population per year. Additionally, commonly used tests include the microbial culture method, urine antigen testing, and the more recently launched advanced PCR technique. In response to the COVID-19 outbreak, most countries around the world implemented lockdown conditions.


Water in many commercial building storage systems was left unused for extended periods, making it susceptible to the growth of Legionella species. Many countries' governments have recommended mandatory testing of these water sources before resuming operations at these sites to prevent a Legionella outbreak.



  • For instance, Wirehouse, an Employment Law & Health and Safety Service provider from the U.K., recommends Legionella testing service visits at workplaces to ensure the absence of Legionella species growth.


The market witnessed slow growth during the pandemic due to the temporary halt in manufacturing, disruption in the supply chain, and a shift of the healthcare system's focus toward managing COVID-19. The clinical presentation of Legionella disease is similar to COVID-19 infection, leading to higher testing rates for the coronavirus and a reduction in Legionnaires' disease testing, thus hampering market growth.


However, the market is expected to grow significantly in the post-pandemic era. The pandemic-related lockdowns resulted in stagnant water in empty buildings, potentially increasing the proliferation of Legionella bacteria.



  • For instance, according to the article "Reopening Buildings After Prolonged Shutdown or Reduced Operation," published by the Centers for Disease Control and Prevention in 2021, facilities such as schools and buildings should test hot tubs/spas for Legionella before returning to service. All testing decisions should be made in consultation with facility water management program staff and relevant public health authorities.


Thus, the rising government emphasis on testing water for the presence of Legionella in the post-pandemic period is increasing the demand for Legionella testing, contributing to market growth.


Legionella Testing Market Trends


Growing Adoption of Rapid Testing Methods such as Urine Antigen Testing and PCR to Accelerate Market Growth


The technologies powering molecular diagnostics are rapidly evolving to address the rising cases of infectious diseases. The conventional Legionella testing method, utilizing microbial culture technology, is time-consuming and laborious. However, it was the most preferred test method over the urine antigen test until the emergence of the PCR test, primarily due to its ability to detect Legionella species serogroups. PCR is highly sensitive, with a sensitivity of 95-99%, can detect all serotypes of Legionella species, and provides rapid results. The increasing availability of real-time PCR kits and its expanded geographic reach have resulted in enhanced adoption of this test method globally.

Legionella Testing Market Growth Factors


Growing Prevalence of Legionnaire Disease to Stimulate Market Growth


Legionella bacterial species are commonly found in freshwater reservoirs with an average temperature of 20 to 40 degrees Celsius. They are responsible for causing a respiratory disease known as Legionnaire’s disease. The market is expected to grow rapidly during the forecast period, driven by the increasing incidence and prevalence of this disease, leading to a rise in demand for testing kits.



  • For instance, according to statistics published by the U.S. Department of Labor, about 6,000 Legionella cases are reported each year in the U.S.


Moreover, the rise in the incidence of hospital-acquired Legionella infection and the increasing frequency of testing in these facilities due to stringent regulations will drive the demand for such effective products in the near future.



  • According to a study published by the International Society for Infectious Diseases, out of 16 hospitals located in Taiwan, 10 hospitals (63%) tested positive for Legionella Pneumophila. The hospital's potable water system was found to be the primary source for hospital-acquired Legionella disease.


Stringent Regulations for Regular Water Testing to Spur Market Growth


The presence of various Legionella bacterial species in water reservoirs such as ponds, lakes, swimming pools, warm water showers, and water supply pipes of commercial buildings is a growing public health concern. Outbreaks of Legionellosis result in an increased risk of morbidity and mortality among exposed individuals. Therefore, the suspicion of an outbreak warrants immediate action. The World Health Organization (WHO) provides information and guidance on the assessment of Legionella risk and its proper management in seven principal documents. These documents offer guidance on the evaluation and management of risks associated with water sources, pools, cooling towers, and spa baths. The governments of many countries have enacted regulations to manage Legionella in various types of water systems.



  • For instance, the European Union (EU) formed the European Working Group for Legionella Infections (EWGLI) to control the prevalence of these diseases in various types of water systems. Thus, stringent monitoring of water reservoirs and the launch of rapid testing methods for onsite water testing are anticipated to promote Legionella testing market growth.


RESTRAINING FACTORS


Limited Awareness about the Disease in Underdeveloped Countries to Restrain Market Expansion


Legionella infection is a well-recognized and commonly occurring health concern in developed nations. In response to this, various governments have enacted stringent regulations for diagnosing associated diseases and conducting regular testing of potential sources of infection. On the other hand, there is limited awareness about the bacteria and the diseases associated with it in emerging regions of the world. Also, the failure to diagnose this disease is mainly due to a lack in clinical awareness. The disease is underdiagnosed in many countries due to a lack of proper definition, guidelines, and diagnostic facilities, posing a significant challenge to market growth of Legionella testing.


Studies regarding awareness of this infection in India have found that sporadic cases often go unnoticed due to the burden of other diseases such as bacterial and viral pneumonias and tuberculosis. Thus, limited awareness about the diseases, insufficient diagnostic infrastructure, and slow adoption of advanced diagnostic tools with high costs, such as real-time PCR, are some of the major factors hampering the growth of the market.
