A new study by a team at Virginia Tech has linked the outbreak of Legionnaires’ disease in Flint, MI to the city’s decision to switch its water supply. Flint suffered a surge in cases of Legionnaires’ disease from 2014 to 2015, with nearly 100 people sickened and 12 deaths. The death toll could have been higher, as Legionnaires’ disease often masquerades as pneumonia and goes unreported. Health officials assumed that the city’s decision to switch its water supply from Lake Huron to the Flint River was to blame, but no tests were done at the time of the outbreak. (An…
A retirement community in Maryland is once again struggling to contain Legionella bacteria in its water supply. Three residents of the Lutheran Village at Miller’s Grant in Ellicott City, Maryland were diagnosed with Legionnaires’ disease in late May of this year. County health officials shut off the water after determining that the retirement community was the source of the bacteria. After testing and treating the water, officials turned it back on in early July. The retirement community intended to continue testing until the water was shown to be clear of Legionella. These tests have now shown that there is still…
A water management company has been accused of failure to carry out required tests after several people became ill with Legionnaires’ disease at a New Zealand plant. Solenis New Zealand is a branch of the Delaware-based water treatment company Solenis. The company was contracted by the multinational dairy company Fonterra to manage water quality at its plant in Pahiatua, New Zealand. After 13 people who worked at or near the plant became ill with Legionnaires’ disease or Pontiac fever, an investigation into Solenis’ testing practices was carried out. WorkSafe, the New Zealand government agency that oversees workplace health and safety,…
Legislation mandating that hospitals conduct routine tests for Legionella has paid off in Australia, where a Queensland hospital caught the bacteria in its water supply before patients were infected. A deadly outbreak of Legionnaires’ disease in 2013 prompted lawmakers to require that hospitals perform regular tests for Legionella. As a result of such tests, the Cunnamulla Hospital in southwestern Queensland reported last week that its water system contained Legionella bacteria. Hospital officials responded by chlorinating the water system, replacing water fixtures, and retesting the water supply. Thanks to the mandatory tests and the quick action of the hospital officials, no…
Legionella bacteria in the water supply of the Allegheny General Hospital in Pittsburgh likely caused a cancer patient to contract Legionnaires’ disease. Officials previously believed that the patient, now recovered, had contracted the illness elsewhere, but new tests show that the bacteria originated in the hospital. After a cancer patient who had previously been treated at the hospital was readmitted with respiratory problems at the end of May, doctors tested the patient for Legionnaires’ disease. (Click here for our original blog post on this story.) The test was positive, and the patient was treated and made a full recovery. At the…
A recent investigation into a pneumonia death in Flint has demonstrated the need for hospitals to release Legionella test results and for diligent testing of patients at risk for Legionnaires’ disease. In a June 28 article for Bridge Magazine, Chastity Pratt Dawsey reports on the case of Bertie Marble. Mrs. Marble, a 68-year-old resident of Flint, Michigan, passed away in March 2015 after a spell of ill health. During her final stay at McLaren Regional Medical Center in Flint, Mrs. Marble was diagnosed with “healthcare-associated pneumonia”. McLaren had found Legionella bacteria in its water system in late 2014 but had not revealed…
A birth center in southern England has been cleaned and will soon reopen after having closed for the second time this year because of positive tests for Legionella. Paulton Birth Centre in Somerset was closed for maintenance in early June after a sample of water was found to contain Legionella. The bacteria was found in a section of the center that does not serve patients directly. Now, the water system has been tested again after a cleaning and no Legionella has been found. A spokesperson for the center’s owner, NHS Property Services, said that the water system had been thoroughly…
Recent guests at a North Carolina hotel have contracted Legionnaires’ disease and hotel managers are taking steps to control exposure. Three individuals who stayed at the Meadowbrook Inn and Suites in the mountain resort town of Blowing Rock, NC have tested positive for Legionnaires’ disease. All of the affected guests had stayed at the hotel within 10 days before the onset of their symptoms, and all have undergone treatment and are recovering. The Meadowbrook Inn has a comprehensive water management system in place, including regular testing of water features such as pools and hot tubs. When the disease was reported,…
Testing last week revealed that the water system of a hospital in Pittsburgh, PA has been contaminated with Legionella bacteria. Allegheny General Hospital conducted tests for Legionella in their water supply after a cancer patient tested positive for Legionnaires’ disease. The patient had been discharged on May 20 for respiratory problems but had been readmitted four days later after a relapse; a urine test revealed that the patient had been infected with Legionella bacteria. Though hospital officials believe that the patient had been exposed to the bacteria outside of the hospital, they tested the hospital’s water supply and discovered Legionella…
Image via http://www.unclejohnshandymanservice.com An article from the Wall Street Journal elaborates on some investigations into Legionnaires’ disease outbreaks done by the Center for Disease Control (CDC) in the past 15 years. The results showed that the vast majority of outbreaks were caused by negligence on the part of maintenance employees who did not maintain biocides effectively, repair or change equipment on schedule, or did not adequately maintain the plumbing. These look like easily fixable problems, but it’s more complicated than it seems. The guidelines for preventing Legionella are not standards, and there are virtually no laws requiring specific Legionella prevention. This means…
