A mysterious outbreak of Legionnaires’ disease in a Berlin housing estate has raised concerns about the slow response of landlords to health crises and the lack of transparency with tenants.
The Hidden Dangers of Legionnaires’ Disease in Affordable Housing
Legionella is a type of bacteria that grows in warm water environments.
It is commonly found in air conditioning units, cooling towers, and hot tubs.
When people inhale aerosolized water droplets contaminated with Legionella, they can develop 'Legionnaires' disease' , a severe form of pneumonia.
According to the CDC, there are over 8,000 reported cases of Legionnaires' disease each year in the United States.
Regular maintenance and disinfection of water systems can help prevent outbreaks.
A Growing Concern in Berlin’s High-Deck Estate
An outbreak of the potentially deadly Legionnaires’ disease in a housing estate in Berlin has raised concerns that big housing companies are too slow to react to major health crises or keeping their tenants informed. The incident highlights the need for better communication and action from landlords when it comes to maintaining the health and safety of their tenants.
Legionnaires' disease is a type of pneumonia caused by the Legionella bacteria.
It is typically contracted through inhaling water droplets contaminated with the bacteria, often found in air conditioning units, cooling towers, and hot tubs.
According to the CDC, there are approximately 8,000-18,000 cases reported annually in the United States.
Symptoms include fever, cough, and shortness of breath, which can be severe and even fatal if left untreated.
The Rise of Legionella Bacteria
Legionella bacteria cause Legionnaires’ disease, a potentially deadly form of pneumonia. The bacteria can spread through water vapor, but not through drinking or person-to-person contact. In this case, the outbreak was linked to contaminated water in the ‘High-Deck‘ estate, where tenants reported experiencing flu-like symptoms and breathing difficulties.
Failure to Inform Tenants
Tenants of the housing estate say their landlords have failed to keep them properly informed about the outbreak. Despite health authorities imposing a shower ban on 332 apartments, Howoge, the state-owned housing company, was slow to respond. Tenant Brianne Curran believes she contracted Legionnaires’ disease two months before being told about the contamination.
‘It was quicker to get the news onto national television than it was to get a response to my email from Howoge,’ said ‘Curran’.

Containment Measures
Howoge eventually implemented containment measures, including replacing water fittings and giving residents shower heads that filter out the bacteria. However, some tenants have expressed concerns about the effectiveness of these measures.
‘They are relying on outdated systems and dismally imagined protocols,’ said ‘Curran’.
Legionnaires' disease is a type of pneumonia caused by the Legionella bacteria.
Common symptoms include fever, chills, cough, and shortness of breath.
In severe cases, patients may experience headache, muscle pain, and gastrointestinal issues.
According to the CDC, Legionnaires' disease often affects older adults and those with weakened immune systems.
Early diagnosis is crucial for effective treatment, which typically involves antibiotics.
If symptoms persist or worsen, medical attention should be sought immediately.
The Broader Issue of Affordable Housing
The ‘High-Deck‘ incident points to wider issues with affordable housing in major cities. In recent years, there have been Legionella outbreaks in cities around the world, resulting in several deaths. Tenants often feel frustrated by a lack of communication and action from landlords when things need to be fixed.
There are potential long-term fixes, however. Some European cities are introducing innovative ways to create modern affordable housing, such as student houses made out of recycled shipping containers. Water monitoring apps and smart water systems can also help prevent bacterial contamination.
‘The High Deck’s Legionella crisis shows the housing issues cities face worldwide,’ said ‘Curran’. ‘Perhaps one way Howoge could show they are sorry to one of their main stakeholders is by opening their doors to developers/architects of such successful, affordable and sustainable housing projects.’‘
A Call for Action
As the situation in Berlin continues to unfold, it’s clear that something needs to change. Tenants need better communication and action from landlords when it comes to maintaining their health and safety. The public needs to be informed about potential risks and the steps being taken to address them.
By working together, we can create modern affordable housing that prioritizes the well-being of its tenants. It’s time for big housing companies like Howoge to take responsibility for the health and safety of those they serve.
