13 Elmira residents are recovering from Legionnaires’ disease.  The Chemung County Department of Health and the New York State Department of Health are investigating the Elmira Legionnaires Outbreak.  Legionnaires disease is a serious and often deadly lung disease.  Overall, 10% of Americans who develop Legionnaires disease die.

A cooling tower at Elmira Heat Treating may be the source of this Legionnaires outbreak.  Cooling towers are a common source of Legionnaires disease outbreaks. Elmira Heat Treating has three cooling towers.  One cooling tower tested positive for Legionnaires disease.

12 people may have developed Legionnaires’ disease in the East Texas State Fair Legionnaires Outbreak.  The Northeast Texas Public Health District alerts the public in East Texas that:

Anyone who attended the East Texas State Fair in Tyler during September 2019 and is sick due to symptoms of Legionnaires’ disease is urged to discuss Legionnaires’ disease with your health care provider immediately.

Public health investigators are working to identify how the outbreak happened.  7 confirmed cases of Legionnaires Disease and 5 possible cases have been linked to the East Texas State Fair, which was help on September 20th – September 29th.

The Tyler Morning Telegraph reports that, “state health investigators have determined that all who are sick attended the East Texas State Fair that took place Sept. 20-29 in Tyler. If exposed to the disease, attendees already would have exhibited symptoms.”

USA – Legionnaires’ disease: 3rd death reported in North Carolina outbreak

Outbreak News Today CDC legionella

North Carolina health officials have reported a third Legionnaires’ disease fatality linked to the NC Mountain State Fair, held September 6-15, 2019 at the Western North Carolina Agricultural Center in Fletcher, NC.

As of Oct. 14, 140 cases of Legionnaires’ disease or Pontiac Fever had been reported in residents of multiple states and North Carolina counties.

Buncombe, Henderson and Haywood counties have seen the most cases with 49, 34 and 12, respectively. Ten cases were reported in out of state residents.

The outbreak has been linked to a hot tubs display at the Davis Event Center at WNC Ag Center.

Legionella bacteria are found naturally in the environment. These bacteria can become a health concern when they grow and spread in human-made building water systems like hot water tanks, cooling towers of air conditioning systems, decorative fountains and hot tubs or spas that aren’t properly maintained.

Approximately 200 cases are reported annually in North Carolina.

North Carolina state health officials were first notified about an increase in the number of Legionnaire’s disease cases in Buncombe and Henderson counties about one week ago.

To date, health officials have reported 83 Legionella cases (79 Legionnaires’ disease and 4 Pontiac fever), including one fatality.

The most cases have been reported from Buncombe (34) and Henderson (21) counties, with 11 other counties affected plus 5 South Carolina cases.

The North Carolina Department of Health and Human Services has announced an outbreak of Legionnaires’ disease potentially linked to the Mountain State Fair in North Carolina. As of today, there are 32 confirmed illnesses and one person has died. According to the health agents, “The source of the outbreak is under investigation. Many of the cases reported attending the NC Mountain State Fair, held September 6-15, 2019 in Fletcher, NC.” The investigation in ongoing.

As Legionnaires’ disease is typically transmitted through contaminated water sources, the health agencies are investigating any rides that may have water. “Features, exhibits, and rides that incorporated some type of water exposure that created droplets which came in contact with visitors will be our focus,” Steven Smith, Henderson County’s Director of Health.

North Carolina state and local health officials report investigating multiple cases of Legionnaires’ disease reported in individuals who attended the NC Mountain State Fair in Fletcher, NC, Sept. 6–15, 2019.

“We don’t yet know whether people might have been exposed to Legionella bacteria at the NC Mountain State Fair,” said State Epidemiologist Dr. Zack Moore. “As a precaution, we are recommending that anyone who went to the fair and has symptoms of pneumonia, like cough, fever or shortness of breath, see a doctor right away and talk with them about Legionnaires’ disease.”

Legionnaires’ disease is a form of bacterial pneumonia (lung infection). A person may develop Legionnaires’ disease when they breathe in mist or accidentally swallow water into the lungs that contains Legionella bacteria.

In North Carolina, more than 150 cases of Legionnaires’ disease are reported each year. Symptoms typically begin two to 10 days after exposure and can include cough, shortness of breath, fever, muscle aches and headaches. Legionnaires’ disease is a serious illness but can be treated effectively with antibiotics. Legionella bacteria can also cause a milder flu-like illness called Pontiac fever, which resolves without treatment.

Most healthy people exposed to Legionella bacteria do not get sick. The people at highest risk for Legionnaires’ disease include individuals 50 years or older, current or former smokers, and those who have a chronic lung disease or a weakened immune system.

Pneumonia resulting from exposure to Legionella — although uncommon and affecting only 1 in 100,000 in Europe — has a higher than 10% fatality rate. The pathogenic bacterium Legionella pneumophila has more than 300 toxins that it uses to infect humans. Once the aerosols containing the bacteria are inhaled, Legionella enters the lungs where it starts infecting human cells, causing pneumonia.

Legionella toxins especially target the innate immune pathways facilitating the survival of the bacteria inside human cells and allowing the replication of the bacteria. Due to the large number of toxins it is difficult to see the effects of deleting one or multiple of these toxins on the Legionella infection capacities. This is further complicated by the fact that several toxins with similar functions exist inside the bacteria. This makes Legionella hard to target with specific drugs.

USA – Sheraton Atlanta Legionnaires’ disease: 11 confirmed, 55 probable outbreak cases

In a follow-up on the Legionnaires’ disease outbreak linked to the Sheraton Atlanta Hotel, the Georgia Department of Public Health (DPH) reports 11 lab-confirmed cases of Legionnaires’ disease and 55 probable cases of Legionnaires’ disease related to this outbreak through July 29.

No deaths have been reported.

Probable cases are people who had illness consistent with Legionnaires’ disease, including pneumonia diagnosed by a clinician or chest X-ray, but without laboratory confirmation. The number of probable cases can change based on additional testing and lab results.

Since the first cases of Legionnaires’ disease were confirmed two weeks ago, epidemiologists from DPH and Fulton County Board of Health (FCBOH)  have been reviewing hundreds of survey responses from individuals who stayed at or visited the Sheraton Atlanta between June 12 and July 15, 2019. The surveys help identify people who may have been ill, especially those with severe illness like pneumonia.
