This past Monday, February 19, a Philadelphia-based global molecular solutions company called Invisible Sentinel Inc. announced its first-in-class Legionella species assay had been verified and adopted by a Centers for Disease Control (CDC) ELITE Certified Laboratory called Q Laboratories, Inc. The CDC ELITE, or Environmental Legionella Isolation Techniques Evaluation, is a CDC designation for labs that have shown proficiency with isolating, growing, and identifying Legionella from samples collected in the environment. Traditional screening methods, however, can often take up to two weeks so a development like the one touted by Invisible Sentinel would certainly mark a significant improvement. The new…
Over the course of this blog, many subjects have been covered however perhaps as a reminder and as a step back, it is prudent to review exactly how individuals contract Legionnaires’ disease. As mentioned before, Legionnaires’ disease is often contracted by breathing in aerosolized water (and in some cases, soil) that has Legionella bacteria. As such, Legionnaires’ disease cannot be given from one individual to another. The Legionella bacteria grows the best in warm temperatures so can often thrive in locations like cooling towers, evaporative condensers, and hot water tanks. The Legionella pneumophila causes around 90% of all Legionnaires’ disease cases and can survive…
Last Wednesday, officials with the Illinois’ Department of Human Services made a statement that a patient at the Chester Mental Health Center, a mental health facility in southern Illinois, had tested positive for Legionnaires’ disease. In the statement, the officials also said that the patient from the mental health facility was being treated and is in stable condition. In response to the incident, the Chester Mental Health Center stated that it would be working with the Illinois’ Department of Public Health to find the source of the bacteria and maintain extensive monitoring other patients. In a news release earlier this week…
Over the course of the past month, we have not only covered various sporadic cases and outbreaks of Legionnaires’ disease, but have also tried to shine light onto other developments within the field. A seemingly simple question, however, has been on my mind as I continue to go through these stories; is there a vaccine that could prevent individuals from being at risk to Legionnaires’ disease? And if there is not a vaccine, then why not? Well the first question is relatively simple to answer; no, there are currently no vaccines for Legionnaires’ disease. There have certainly been attempts to…
NSF International, a global public health organization that develops standards and tests and certifies products for the water, food, consumer goods and health sciences industries will be hosting the first ever Legionella Conference alongside the National Science Foundation. The conference, specifically entitled the Legionella Conference 2018 – Managing Legionella and Other Pathogens in Building Water Systems, will be occurring from May 9-11, 2018, in Baltimore, Maryland and represents the first time experts with various backgrounds including from academia, medicine, industry, public health and government will come together in order to discuss Legionella along with other related pathogens which can be found in water distribution systems. Specifically, the conference…
This past weekend, it was reported by WKBW Buffalo that the Buffalo Public Schools were investigating a potential claim of Legionella being found at the Districts office. According to the report, the bacteria was found in a single water sample and furthermore, according to a spokesperson for the Buffalo Public Schools, it is unclear whether this finding is accurate. Part of the reason for the lack of clarity is due to there not being any current standards for Legionella testing in buildings that are not health related. This is in addition to the fact that individuals associated with the Buffalo…
In a previous post, we discussed the origins and very early beginnings of Legionnaires’ disease. In this post, we are hoping to slowly move through time and discuss some significant outbreaks and moments of Legionnaires’ disease history. Perhaps the first major outbreak after the 1976 Philadelphia incident would be with Stafford, England. In April 1985, approximately 175 people were admitted into the Kingsmead Stafford Hospital with pneumonia. Of these cases, around 28 individuals ended up dying with the origin of the infection being discovered to be the Stafford District Hospital. About a decade later, in March 1999, the Bovenkarspel legionellosis…
An earlier post of ours discussed the discovery of Legionella at the Illinois State Capitol complex. In our initial discussion, it was found that one out of the ten locations which were tested was found to have Legionella and furthermore, was at the Armory, which was vacant and uninhabited. Now, testing appears to suggest a larger incident occurring. According to state officials, preliminary testing shows Legionella bacteria being found in numerous other locations around the Illinois State Capitol complex. As the (Springfield) State Journal-Register reports, the Illinois Secretary of State’s office sent out a memo on Wednesday stating that there…
On Tuesday, February 6, 2018, a Brooke Army Medical Center staff member was confirmed to have Legionnaires’ disease. This confirmation was made by the Brooke Army Medical Center spokesman Robert Whetstone on Wednesday, February 7, 2018 and in addition to the two previous cases of Legionnaires disease reported last August, makes this incident officially an outbreak according to the Emerging and Acute Infectious Disease Guidelines. According to Mr. Whetstone, “the health and safety of our patients and staff is our top priority, and we are working diligently with local and regional public health officials to investigate this matter,”. In addition, Whetstone added that Brooke…
Once more, it appears perhaps a prudent time to take a step back to examine Legionnaires’ disease. As such, while in a previous post we discussed some of the signs, symptoms, and diagnostic methods for identifying Legionnaires’ disease, today’s post seeks to review the history of Legionnaires’ disease. While Legionella bacteria and Legionnaires’ disease has presumably existed for a very long time, it was only truly discovered and researched after an outbreak in 1976. At a convention of the American Legion in Philadelphia, numerous attendees began to suffer from this type of pneumonia, i.e. lung infection, a phenomena which garnered…
