Health officials are warning about the presence of harmful bacteria, such as legionella, in hot tubs this summer.
Legionnaires' disease, a severe bacterial infection that can lead to pneumonia, is a significant concern as it can lurk in hot tubs and infect people who use the tub.
Proper maintenance, regular cleaning, and disinfection of hot tubs are essential to minimize the risk of infection.
By staying informed and taking necessary precautions, individuals can continue to enjoy the benefits of hot tubs while prioritizing their health and well-being.
Legionella, the bacteria responsible for Legionnaires' disease, can lurk in hot tubs, as well as other sources such as air conditioning units, taps, and showers.
Dr Simon Clarke, a renowned microbiologist from the University of Reading, warns that legionella bacteria can be found in various environments, including complex plumbing systems, showerheads, and decorative fountains.
He told MailOnline: "It’s even been found in car washer bottles filled with tap water instead of detergent windscreen washer."
Legionnaires' disease is more prevalent in warm climates and tends to thrive in large buildings like hotels and office blocks, where it can grow within water supplies.
Contamination can occur in swimming pools and dirty air conditioning units that accumulate warm, stagnant water, which is then dispersed as droplets in the air and inhaled by unsuspecting individuals.
However, it is essential to note that legionella can also persist in showers and taps that have not been used for extended periods.
Experts recommend taking certain precautions to minimize the risk of contracting Legionnaires' disease.
Running taps and showers before direct contact with the water is strongly advised, particularly in unfamiliar or infrequently used settings.
Health and safety guidelines stipulate that hot water supplies should be maintained at a minimum temperature of 50°C, as the bacteria cannot survive at this heat.
Similarly, cold water should be kept below 20°C to prevent bacterial breeding.
For individuals who own hot tubs or home spas, regular maintenance is crucial.
Draining, cleaning, and disinfecting the hot tub or spa on a consistent basis is highly recommended to mitigate the risk of infection.
Additionally, removing any buildup around showerheads is advised as it can trap water and potentially harbour bacteria.
While Legionnaires' disease is not a day-to-day concern for the general population, certain groups are at a higher risk of infection.
Individuals over the age of 45, smokers, those with pre-existing lung conditions, compromised immune systems, or chronic health conditions like diabetes or kidney failure should exercise extra caution.
These individuals are more vulnerable to severe complications from the disease, which can be fatal in some cases.
