Leeds father, 44 years old dies with Legionnaires disease

Sadly, there has been another reported loss of life to Legionnaires disease in England  Heartbroken Leeds partner’s tribute to ‘one-in-a-million soul mate’ Martin Bohanna, 44, after sudden death – Leeds Live (leeds-live.co.uk)

In this article we review the rare but serious lung condition known as Legionnaires’ disease looking at its diagnosis, treatment and consider whether it is preventable.


Legionnaires’ Disease Diagnosis, Treatment & Prevention

We start by reviewing typical symptoms and what’s involved in diagnosing the condition, how it can be treated and conclude with measures that can be put into place to control the risks to people, including the management of water safety in engineered water systems.

What is legionellosis?

Legionellosis is the collective term for diseases caused by Legionella bacteria, and although we mainly talk about the most serious, Legionnaires’ disease, this is just one of the infections which can be caused by this bacteria.

One of the other more significant diseases it can cause is called Pontiac fever.

Both diseases affect the lungs, although Pontiac fever is less serious and is diagnosed and treated in differently.

Legionnaires’ disease diagnosis

Legionnaires’ disease has an incubation period of between 2 and ten days after exposure to Legionella bacteria. Symptoms can include:


One of the classic signs associated with Legionnaires’ disease is a serious lung infection. Lung infections of this nature, which are similar to pneumonia, are usually diagnosed by X-ray.

Once a patient has been confirmed to be suffering with a lung infection, further tests are carried out to establish the type of bacteria which is causing the infection.


Other factors to be considered as part of the Legionnaires’ diagnosis

Doctors will also consider other factors when trying to establish a Legionnaires’ disease diagnosis. People who are over the age of 45, who have underlying health conditions or are heavy smokers are more likely to develop the disease than the population at large.

Within a hospital environment, patients with underlying health issues, those with a compromised immune system including cancer patients, and people who have had an organ transplant are more susceptible to Legionnaires’ due to the anti-rejection drugs they are taking.

Patients who have recently returned from a cruise, or other type of overseas holiday are also at higher risk, given that the bacteria can thrive in poorly managed water systems including showers, spa pools and air conditioning systems.

Finally, if there have been other cases of the disease locally, then this may also lead to a more obvious diagnosis.

Legionnaires’ disease treatment

Unlike Pontiac fever, doctors can’t adopt a “wait and watch” approach with the much more serious condition of Legionnaires’ disease. Legionnaires’ has a mortality rate of around 10%.

This figure is much higher for people who have underlying health issues, are already in hospital or a care home when they contract the disease.

People who are known to be suffering from Legionnaires’ disease will need to be treated in hospital. Many will have to be treated in an intensive-care unit because of the serious nature of the condition.

Currently, the main treatment for Legionnaires’ disease is the use of antibiotics, which are given intravenously through a cannula in the back of the patient’s hand.

As Legionnaires’ disease is potentially so serious, doctors will usually start treatment with antibiotics used for pneumonia and chest infections while waiting for the laboratory to confirm the diagnosis. Each course of antibiotics lasts between 1 and 3 weeks, depending on the severity of the infection.

If patients are having difficulty breathing, they may receive additional oxygen through a mask to help their lungs. Some particularly ill patients might require to be ventilated artificially for a period.

Many people who have recovered from Legionnaires’ disease continue to suffer symptoms for many months or even years. Common lingering symptoms include fatigue and neurological problems.


Can Legionnaires’ disease be prevented?

From an individual perspective, there isn’t much that can be done to prevent people contracting Legionnaires’ disease. It’s a public health issue, and one which we rely on other people to control on our behalf.

In the UK, the Health and Safety Executive (HSE) takes a lead on controlling the risks from Legionella bacteria and Legionnaires’ disease in the workplace.

Legionella is mainly associated with domestic water systems (taps and showers), cooling towers, evaporative condensers, spa pools and hot tubs, air conditioning and dry/wet cooling systems.

Any business operating this type of water system, including residential landlords, has certain obligations under health and safety law to protect their employees and others from harm.

Legionnaires’ disease and UK law

In the UK businesses simply cannot ignore the risk of Legionnaires’ disease. Legislation, including the Health and Safety at Work etc Act 1974 sets out the legal obligations of businesses and landlords to protect their employees and others.

The Health and Safety Executives Approved Code of Practice ACOP L8 further clarifies what is required to control the risks from Legionella bacteria. There are four main things which an employer has to do if they are to meet their legal obligations in this area.

Identify the risk with a legionella risk assessment

Performing a legionella risk assessment is about auditing your premises and its water systems with the aim of identifying risk areas for Legionella bacteria. In order to do this properly, you need to understand where and how the bacteria grows and spreads.

If you haven’t the expertise internally to do this, then you might choose to get a specialist company such as Water Treatment Services to carry out the legionella risk assessment instead.

Your risk assessment should consider all aspects of your water systems and the risks they may create. This might include, but is not limited to the incoming water sources, water storage such as tanks, plumbing and distribution networks, processes using water, outlets including showers and taps, cooling towers, spa pools and hot tubs, water features and decorative fountains… in fact anything that stores or uses water.

The person responsible for managing the risks presented by legionella, usually called the responsible person should be properly trained to do their job and should consider issues such as:


    How water is recirculated around the system or stored.


    If there are conditions which might allow bacteria to grow.


    Sources of nutrients like sludge, biofilm or organic matter.


    Water temperatures.


    Whether water droplets are produced and dispersed in to the atmosphere.


    The susceptibility of employees and others.

Keeping records of what you do

In the UK, health and safety law states that only businesses with 5 or more employees need to keep formal written records, but it’s usually advised that all businesses do so. Records of testing and maintenance should be kept for at least two years. They can be paper records or on computer.

The Health and Safety Executive, or Care Quality Commission (for care homes) will expect to see comprehensive records in the event of an outbreak of Legionnaires’ disease, and you should be able to prove that you have been taking reasonably practicable precautions to minimise the risks of an outbreak occurring.
