Hot Water System Malfunction Leads To Legionnaires Disease In Brisbane

A woman in the southern Brisbane suburb of Camira has recently contracted the potentially dangerous disease Legionnaires when a part of her hot water system malfunctioned.

This follows an incident earlier in the year when an office worker in Melbourne contracted the disease from an unknown source, putting her in a critical condition.

With statistics of such hospitalisations in the United States as high as 18,000 people each year, it is important that all homeowners are aware of the potential threat in order to prevent anything tragic happening to themselves or loved ones.

In the case of the Camira woman the circulating pump failed on her hot water system, meaning there were no solar gains applying heat to the water. She unfortunately was unaware of the manual process to boost the system.

What is Legionnaires Disease?

The bacteria Legionella got its name after a major outbreak in July 1976 at a Philadelphian hotel which was hosting a convention for the Pennsylvanian American Legion. Although the bacteria had previously existed, this was the first documented outbreak.

The disease officially called “Legionellosis” is a dangerous and even sometimes fatal type of pneumonia. Though many cases are often not severe, it is believed that as high as 10 per cent of cases are fatal; children and the elderly are particularly at risk.

There are officially more than forty strains of the bacteria Legionella, though thankfully only a small few transmit
diseases to humans.

The symptoms can sometimes be hard to distinguish from a severe flu, which means there is probably many unreported cases. These are the warning signs:

Severe headache
Breath shortness
Achy muscles
Sometimes a dry cough

After the time of infection these symptoms take between 2 – 10 days to appear.

How To Prevent Legionella From Spreading

The Australian hot water systems standards state that hot water must be stored at a temperature more than 60 C, which prevents the growth of harmful bacteria. However, as shown in the above case, maintenance issues can occur which lower hot water system temperatures to the 30 – 40 degree range which is optimal for the growth of Legionella.

It is great advice then to keep a keen eye on your home’s hot water system, ensuring that it is operating in the correct way while maintaining the required temperatures.
