A new report by the Centers for Disease Control and Prevention (CDC) shows that cases of Legionnaires’ disease have been increasing since 2003. Incidence of the disease remained stable from 1992 to 2002, with an average of 1,221 reported cases each year. The average number of cases dramatically increased between 2003 to 2018 to 4,369 reported cases each year. The East North Central, Middle Atlantic, and New England regions were most affected by the increase in cases. Additionally, the highest incidence was in Black or African American persons. Increasing racial disparities, geographic focus, and seasonality were most associated with the…
As recently reported on our blog, there is an outbreak of Legionnaires’ disease in Harlem, NY. Additionally, dozens are sick after they were exposed this month at Duke University’s fantasy basketball camp. All over the country, cases of Legionnaires’ disease appear to be on the rise. Michigan noted an alarming statistic in July of an increase of 569% from July 2020. This is a huge spike in reported Legionnaires’ disease cases, with over 100 cases being reported in Michigan in the first half of July alone. [1] Many individuals are returning to buildings like schools and offices that have been…
The CDC Released Recommended Best Practices for the Disinfection of Hot Tubs that Contain Legionella
The CDC recently published recommendations for the best practices of disinfecting a hot tub that contains Legionella. It is vitally important that hot tubs are properly disinfected when Legionella is found. Hot tubs are a well-documented source of Legionella, the bacteria that causes Legionnaires’ disease. As the water heats up, some of the water particles are aerosolized. These are then inhaled by those in and around the hot tub. If these particles contain Legionella, there is a chance that the individual who inhaled it could get very sick. The first step in the disinfection process is to close the hot tub immediately.…
Outbreaks of waterborne illness, like Legionnaires’ disease, have been on the rise over the last several years. An outbreak associated with recreational water is defined as the occurrence of similar illness in two or more persons whose illness are epidemiologically linked by location and time of exposure to persons using recreational water. The CDC recently published in their Morbidity and Morality Weekly Report (MMWR) a report on Outbreaks Associated with Treated Recreational Water in the United States from 2015 through 2019. The report covers important statistics about waterborne illness outbreaks occurrences and recommend implementing new Legionella control guidelines. From 2015-2019,…
Continued from the last post, this post will explore the results of the CDC study and estimate the actual burden of these waterborne diseases. There were 6,630 deaths attributed to waterborne diseases. Legionnaires disease had the second highest number of deaths of the 17 waterborne illnesses studied. Legionnaires disease also had the second highest cost per hospital stay of all the illnesses at approximately $37,200. The 17 waterborne diseases incurred $3.33 billion in total hospitalization and emergency department costs. This amount included $1.33 billion in commercial insurer payments, $1.52 billion in Medicare payments, and $284 million in Medicaid payments. 7,150,000 illnesses attributed to waterborne…
The Centers for Disease Control (CDC) has recently published a new study estimating the burden and direct healthcare costs of infectious waterborne diseases in the United States. They chose to study waterborne diseases that were likely to causes substantial illness or death, and this includes Legionnaires disease. The goal of this study is to help direct preventative action moving forward and set public health goals. New information from the CDC estimates total illnesses, emergency department visits, hospitalizations, deaths, and direct healthcare costs for 17 waterborne infectious diseases, Legionnaires diseases included. The CDC determined about 7.15 million waterborne illnesses occur annually. …
In the United States since 2000, reported cases of Legionnaires disease have been steadily increasing. The CDC estimates that there are approximately 5,000 cases and 20 outbreaks of Legionnaires disease reported annually in the United States. [1] The majority of these cases are preventable, as they occur when buildings and facilities fail to properly maintain their water systems. Researchers estimate the economic burden of Legionnaires disease cases in just one year tops over $800 million. In 2014, the exact figure of the economic burden of Legionnaires disease was approximately $835 million. This estimate includes medical expenses, and the productivity losses cause…
Earlier this year, the United States Centers for Disease Control and Prevention issued guidance for reopening buildings that have been closed due to the COVID-19 pandemic. Because Legionella bacteria is at an increased risk of growing in stagnant water, the CDC published a list of 8 steps business and building owners should take to minimize Legionella growth before opening, which included properly maintaining the building’s water heater to at least 140 Degrees Fahrenheit, cleaning all cooling towers of stagnant pools of water, and flushing out all faucets before use.[1] As of late September, the CDC has updated its guidance for…
Ironically, the United States Centers for Disease Control and Prevention says it has closed several of its buildings in Atlanta because Legionella bacteria have been found in their water systems. These bacteria likely grew because of the pandemic shutdown. Legionella, which grows in warm or stagnant water, causes a deadly form of pneumonia. Left untreated, Legionnaires Disease can kill a person within weeks, and when treated properly can still take more than a year to recover from. The CDC says Legionella bacteria is a problem that people across the country need to be on the lookout for, especially now. The…
Jules Zacher has been retained by two persons who contend they have contracted Legionnaires disease at the Sands Resort in Hampton New Hampshire. An Order issued by the New Hampshire Department of Health and Human Services indicates that the bacteria that causes the disease has been found in a hot tub, water heater, outdoor shower hose, and shower heads or sinks. The state Department of health has ordered the Sands Resort to notify all guests of the outbreak and to hire a consultant to remediate. Testing by the CDC indicates the legionella bacteria was found in shower heads or…
