A free standing cold water humidifier was linked to a
Legionella (Lp1) infection in an infant that had for six weeks also been
receiving corticosteroid treatment for shortness of breath and wheezing. The
humidifier had been filled with tap water and not regularly cleaned. The infant
was admitted to the hospital in February this year due to high fever, cough,
wheezing, and vomiting, and died two weeks later despite antibiotic treatment.

Legionnaires' disease found in water at Seneca Towers
Legionnaires’ disease bacteria have been found in the water at the Seneca Towers apartment complex, apparently leading to at least two known cases of the illness.
Residents at the high-rise apartment building at 200 Seth Green Drive have been told not to use the water because of the positive testing.
“To reduce potential health risks to residents,” said Jeffrey Hammond, a spokesman for the New York State Department of Health, “the facility has implemented infection control measures on the recommendation of the state and county health departments, which include a number of water-use restrictions.”
obs: Este caso como muitos outros, indica que podemos ter problemas com a Legionella em qualquer ambiente, inclusive em nossa própria casa.

Legionnaires Disease Outbreak in PA Puts Hotel Guests at Risk
At a hotel in Grantville, one person and possibly more have been infected by bacteria that cause the deadly Legionnaires’ disease. A source at the Pennsylvania Department of Health is confident that recent guests who may have been exposed to Legionella bacteria have been notified and that “… there is no reason to believe there is a general risk to the community.”
People with Legionnaires’ disease, also known as Legionellosis, are generally infected after inhaling airborne particles containing the bacteria. When large water systems are poorly maintained, Legionella can quickly breed and contaminate components such as faucets and showers or even hot tubs and central air conditioning systems. Though the bacteria can be detected with a simple water test, many buildings have not implemented testing guidelines.
Up to 30 percent of Legionnaires’ disease can result in death according to the Centers for Disease Control. When antibiotic treatment is delayed, fatalities can reach up to 50 percent.

Legionella - Dentistas
Primary Care Dentists & Legionella Control
Second Element provides vital advice and control measures to ensure the health and safety of dental staff and patients by controlling legionella bacteria within dental unit water lines.
Richard Danielson, Director of Second Element, said research at the Centre for Applied Microbiology and Research, Porton Down, showed that of 55 water samples from dental surgeries in the south-west of England, 52 samples failed the European Union drinking-water safety standards.
Water lines were found to contain bacteria including legionella. Oral streptococci, normally present in the oral cavity, was found in 10% of the samples tested. Studies have shown that up to 25% cent of DUWLs are contaminated with legionella and 95% of water in general dental practice DUWLs fails current EU potable-water guidelines on microbial load.
Legionella bacteria can be transmitted to dental staff and patients by inhalation of contaminated water droplets or aerosol generated by water-cooled high speed dental instruments. It is therefore essential to ensure that the water used during dental procedures is of a quality that does not pose any threat or risk to health to either staff or the patient.
All dental practices must perform a legionella risk assessment plus water quality testing performed. Each dental practice must also have a written document of procedures and measures to maintain the control of legionella. This must be devised by a competent person who can be a member of the Legionella Control Association.

Legionnaires' kills 11 people in Quebec City
CBC News
Last Updated: Sep 2, 2012 1:25 PM ET
Stagnant water in highrise cooling systems like this one is believed to be responsible for the spread of legionnaires' disease in Quebec City. (CBC)Related

Quebec's public health board says legionnaires' disease has claimed one more life in Quebec City, raising to 11 the number of people who have died from complications.
As of Sunday, 169 people had been infected since July.
On Friday, the public health board said it was seeing fewer cases of infections caused by the disease.
According to authorities, the overall number of patients being admitted with the infection seems to be tapering off. The city has inspected and disinfected 130 cooling towers around the city.
On Friday, Quebec City Mayor Régis Labeaume said he wants the public health board to release the locations of buildings where officials have discovered legionella bacteria.
Labeaume has also asked regional public health director François Desbiens to maintain a high level of honesty while investigating the outbreak.
According to the public health department, many building owners have failed to respond to the government's request to inspect their cooling towers.
Quebec's Public Security Minister Robert Dutil has demanded a coroner's inquest into the matter.
The potentially deadly legionella bacteria can grow in stagnant water and then spread in droplets through ventilation.
Heavy smokers and people with weak immune systems are most at risk of catching the disease, which is not contagious. Symptoms include persistent fever, coughing and difficulty breathing. Most people are not at risk.
The disease can be treated with antibiotics if it is diagnosed in time. There has never been a documented case of drug-resistant legionella.
This order was effective as of Saturday.
Officials inspecting the cooling towers are giving owners information kits on how to maintain a level of sanitation that conform to the new standards.
In total, 130 towers in 75 establishments were inspected. Thirty-one of these were inspected twice, most of them in the Saint-Roch and Saint-Sauveur neighbourhoods.
On Friday, the organization representing Quebec's master plumbers warned that people who lower the temperature on their water-heaters to save power could be exposing themselves to the bacteria.
In a release, the organization asks people to maintain a temperature of 60 degrees Celsius.
The group said it took part in developing a national standard of heating water to 60 degrees before cooling it.
This strategy was recognized as one of the best to protect people against legionella and burns.

City seeks better upkeep
Desbiens said the regional health authority has ordered that building owners keep a minimum of chlorine in the cooling towers' water at all time.This order was effective as of Saturday.
