Doesn't pass the smell test.
First, I'm not defending Hitlery. Far from it. That being said:
Causes and Common Sources of Infection
Legionella is a type of bacterium found naturally in freshwater environments, like lakes and streams. It can become a health concern when it grows and spreads in human-made water systems like
How it Spreads
After Legionella grows and multiplies in a building water system, that contaminated water then has to spread in droplets small enough for people to breathe in. People are exposed to Legionella when they breathe in mist (small droplets of water in the air) containing the bacteria. One example might be from breathing in droplets sprayed from a hot tub that has not been properly cleaned and disinfected.
Less commonly, Legionella can be spread by aspiration of drinking water, which is when water “goes down the wrong pipe,” into the trachea (windpipe) and lungs instead of down the digestive tract. People at increased risk of aspiration include those with swallowing difficulties. In general, Legionnaires’ disease and Pontiac fever are not spread from one person to another. However, this may be possible in rare cases.

Treatment and Complications
Legionnaires' disease requires treatment with antibiotics (medicines that kill bacteria in the body), and most cases of this illness can be treated successfully. Healthy people usually get better after being sick with Legionnaires' disease, but they often need care in the hospital.
