From New York to California, populations across the United States have an increased risk of a Legionnaires’ disease outbreak. Health officials are increasingly concerned about the continuous uptick of Legionnaires’ disease cases, which have risen steadily since 2000. While the waterborne bacterial disease is relatively rare ― with 6,238 cases nationwideso far this year ― there has been a 13.6 percent increase in cases since this time last year. That’s nearly double the increase of 7.8 percent from 2015 to 2016 in the same time period. The disease is not contagious. It’s contracted when people breathe in water droplets contaminated…
According to new information published by the European Centre for Disease Prevention and Control (ECDC) stainless steel fixtures contain a protective coating that can degrade over time; this degradation encourages the growth of Legionella. It is well known in among those who study Legionnaires’ disease that water containing rust particles is an environment where Legionella can better thrive. Similarly, a stainless steel sink without the protective coating creates an environment conducive to Legionella growth. The ECDC has released a list of more suitable materials for kitchen sink manufactures that are less likely to expose individuals to a higher risk of…
At the same South Orlando location where two individuals contracted Legionnaires’ disease due to being exposed to the legionella bacteria, a cafe inside the LA Fitness has been ordered to cease operations. While the findings of legionella wasn’t enough to prompt officials to shut down the facility, the discovery of health violations including the presences of several live roaches at the cafe, led officials to force the cafe to close its doors. The LA Fitness was investigated in May and tests sent to the CDC came back positive for legionella in June. The LA Fitness in South Orlando was one…
According to the World Health Organization, males are three times more likely to acquire Legionnaires’ Disease than women. (source) As of now, there is no vaccine for Legionnaires’ Disease. The most common form of treatment is typically antibiotics. 75% of reported Legionnaires’ Disease cases are aged 50 years and older. (source) Legionnaires’ Disease is most likely to occur in the summer months. This is because legionella bacteria thrives in warmer water. (source) While Legionnaires’ Disease is typically transmitted by aerosolized water droplets, there have been numerous outbreaks of Legionnaires’ Disease that have been caused by legionella bacteria found in potting…
According to a CDC report based on 27 different outbreaks investigated by the CDC from 2000-2014, released last year, found that hotels and resorts are the most common source of Legionnaires’ Disease outbreaks in the United States. Hotels and resorts were 25 percentage points ahead of long term care facilities and other health care related facilities. Senior living facilities, workplace, and community-associated outbreaks were each found to be responsible for 7% of Legionnaires’ Disease outbreaks. Travel associated outbreaks (hotels and resorts) were found to be the most common source of outbreaks but were also found to have the lowest median fatality rate at…
According to data from the CDC, the number of deaths caused by Legionnaires’ Disease has just about tripled over the past two decades. In 2002 there was 63 deaths directly attributed to Legionnaires’ Disease. The CDC reported 170 deaths caused by Legionnaires’ Disease in 2015, the most recent year that was analyzed. When Legionnaires’ Disease is taken into account as a contributing factor to death, the number of deaths in 2015 increases to 217. Legionnaires’ Disease is the underlying cause of death in 78.3% of fatalities associated with the disease. The data also shows that the mortality rate for Legionnaires’ Disease…
A recent CDC study of the presence of legionella in our nation’s cooling has produced concerning results. Water from 190+ cooling towers from around the country was collected and tested for the presence of legionella bacteria. The CDC found that 84% of those water samples contained at least DNA traces of legionella bacteria. The study also found that 79 of the 196 (~40%) surveyed cooling towers contained live legionella bacteria. These findings were enough for the study’s head researcher, Dr. Anna Llewellyn, to refer to legionella as being “ubiquitous in U.S. cooling towers”. Cooling towers have been strongly associated with outbreaks of Legionnaires’…
In June of last year, the CDC published an article entitled Legionnaires Disease on Rise in US. The report states that the rate of reported cases of Legionnaires’ Disease increased by 286% between 2000 and 2014. The total number of CDC-reported cases of Legionnaires Disease in 2000 was 1,100. By the year 2014 a total of 5,166 cases of LD were reported to the CDC. The most recent figures show that this upward trend has continued into 2015. In 2015, the CDC cites a total of 6,079 cases of Legionnaires Disease, a marked 17% increase of reported cases in just a year.…
A resident of the Charlestown retirement community tested positive for Legionella bacteria and is currently hospitalized. Baltimore County health officials have ordered testing of the water in the Caton Woods Building within the community. Dan Dunne, spokesman for the community, indicated that Caton Woods is a new building and only a dozen or so residents currently live there. New residents were in the process of being moved in, but this has since been halted. The source of the bacteria that caused the resident’s illness has not yet been determined, and the results of the water testing performed at the Caton…
A research group called CU and the CDC comprised of both undergraduate students from Clemson and officials of the Centers for Disease Control and Prevention (“CDC”) had the privilege of naming a new strain of Legionella bacteria after the University- Legionella clemsonensis. The CDC sent 68 strains of Legionella bacteria that didn’t match up to any strains in the current database to Clemson students to analyze. Through sequencing two genes, the students were to determine if the species could be identified as one of the known strains of Legionella, or if the strains were new. These tests revealed that one of…
