How to spread?
Legion bacteria Living in different sources of water-natural and man-made.
People can infection after inhaling water -polluted drops. This may be through breathing in the drops, or fog that was launched into the air from things such as cooling towers, hot ponds, or plumbing systems.
Vallalosa It cannot spread from one person to another, as the PAA said.
Cooling towersIt can be a component of artificial air conditioning components a good environment for bacteria to grow, and these towers can launch large amounts of water drops in the air.
Since the cooling tower emanates from it, it can Create circumstances Observer experts say that water drops contaminated with bacteria to be sent to the air and spread by wind.
This is the reason why they are often associated with the outbreak of corps.
V bribs occur frequently during periods Warm weatherThe researchers found.
Risk factors for the development of a lifetime disease include more than 40 years old, smoking, alcohol consumption, chronic lung diseases, chronic kidney disease, diabetes, immunity, and modern travel.

“In your home, you can reduce the risks through proper maintenance of all fog -producing devices, such as shower heads, hot baths, spiral and moisturizing bathrooms,” the Federal Health Agency notes. “Be sure to clean these devices and disinfect them regularly according to the manufacturer’s directives.”
Ahmed from Hambar River said that the major buildings are often used as a cooling source. As they do, the cooling units justify that water in the air, which we inhale after that.
Ontario’s general health said the bacteria “everywhere” in the environment and most cases in the province intermittently.
Between 2018 and 2023, PAC reported 620 on average Careful cases every year.

In response, the Quebec government has provided new regulations for Operation and maintenance Among the cooling towers, such as the registry and the control plan approved for each tower.
in New BrunswickPublic health officials also recommended the cooling tower record and the rules associated with SCE.
Long -term care house At the eastern end of Toronto Associated with 23 deaths In 2005.
