Legionnaires’ Disease Outbreak in Lincoln: Health Officials Issue Urgent Advisory
Stay Informed: Legionnaires’ Disease Outbreak in Downtown Lincoln
Health officials in New Hampshire are urging residents and visitors to exercise caution when visiting downtown Lincoln, following an outbreak of Legionnaires’ disease. This advisory stems from a series of cases reported in June and July, which have been linked to contaminated water droplets originating from a local cooling tower.
Understanding the Risk: Legionnaires’ Disease and Cooling Towers
What is Legionnaires’ Disease?
Legionnaires’ disease is a severe form of pneumonia caused by inhaling water droplets contaminated with Legionella bacteria. While most people exposed to the bacteria do not fall ill, those who are older, have weakened immune systems, or suffer from chronic medical conditions such as diabetes or lung disease are at higher risk.
The Role of Cooling Towers
Cooling towers, often utilized in air conditioning systems to cool down the air, are potential breeding grounds for Legionella bacteria. These towers use water and fans to disperse water droplets into the air, which can become contaminated and inhaled by unsuspecting individuals.
Recent Outbreak in Lincoln
Details of the Outbreak
In June and July, five individuals developed Legionnaires’ disease, likely due to exposure to contaminated water droplets from a cooling tower situated behind the Riverwalk Resort in downtown Lincoln. Despite ongoing remediation efforts, the cooling tower remains operational, raising concerns about continued public exposure.
Public Advisory and Health Recommendations
Dr. Benjamin Chan, the state epidemiologist, emphasized the importance of public awareness regarding the area of contamination. The highest risk is within a half-mile radius of the cooling tower. Dr. Chan advises individuals, especially those with pre-existing health conditions, to evaluate their health risks before visiting this specific area of Lincoln.
Remediation Efforts and Ongoing Monitoring
Sanitization and Testing
Renee Blood, vice president of Riverwalk Resort, confirmed that initial remediation of the cooling tower began on a Friday and was completed by the following Monday, August 12, by Barclay Water Management Services. Despite the sanitization, additional testing will be conducted to ensure the complete elimination of contamination.
Importance of Continued Operation
Dr. Chan highlighted the necessity of keeping the cooling tower operational to facilitate ongoing testing. This approach aims to confirm that the contamination has been thoroughly addressed and to prevent any further cases of Legionnaires’ disease.
Assessing Health Risks
Who is Most at Risk?
Most people exposed to Legionella bacteria do not become ill. However, the following groups are at higher risk:
– Older adults
– Current or former smokers
– Individuals with weakened immune systems
