Legionella can be the bane of any business; especially caravan parks. Often festering in air conditioning and central heating systems, Legionella is the primary bacteria that causes Legionnaires’ Disease; a type of pneumonia.

A source of relief is that Legionella isn’t incredibly common, though it never hurts to be prepared. For those conscious of the risk, most of your problems will come from a few specific spots within a caravan or a caravan park that should always be addressed and considered.

Legionnaires’ disease is contracted by inhaling fine, airborne water droplets and anyone can be susceptible to the disease. However, the risk of infection is greatly increased for the following:
