The Ministry of Health, Environment and Sustainability says it’s investigating a single confirmed case of Legionnaires’ disease in Grand Cayman, and has ordered environmental sampling at key locations, including Anthony S. Eden Hospital, where initial tests identified Legionella. Officials said the Legionnaires’ disease investigation remained focused on public health precautions and environmental testing.

Officials said the response followed public health protocols, but the press release did not detail what those protocols require, what criteria triggered closures or how long restrictions were expected to remain in place.

Environmental sampling guided the response

Following the sample results, The Ministry said the Public Health Department ordered the immediate closure and remediation of specific areas and the shutting off of water supplies for further investigation. Officials said the measures would remain in place until follow-up testing confirmed that use of the affected areas was safe.

Anthony S. Eden Hospital was among the key locations sampled. The Ministry said the detection of Legionella required a careful and evidence-based response. The action was taken to limit any possible exposure while investigators continued their work.

Chief Medical Officer Dr. Hilary Wolf said Legionella is a naturally occurring bacterium that is commonly found in man-made water systems. She said environmental detection did not mean that illness would follow and said the Ministry’s response was consistent with best practice for a single confirmed case.

“Legionella is a naturally occurring bacterium commonly found in man-made water systems,” Dr. Wolf said. “It is important to note that environmental detection does not mean that illness will follow. As it relates to our directives to the HSA, our response is evidence-based and consistent with best practices relating to a single confirmed case. At this time, there is no evidence of any wider risk. The Ministry and the Public Health Department will continue its oversight to ensure ongoing adherence to the public health protocols. Our investigation continues, and we will continue to monitor the situation closely.”

Members of the public who wanted more information were told they could visit the Ministry’s website or contact the Public Health Department on 244-2889 or 244-6221. Officials said those channels would provide guidance for anyone with questions about Legionnaires’ disease or about the ongoing response.

Oversight and follow-up continued

The Ministry said it would continue to oversee the response with the Public Health Department. That oversight includes monitoring the situation, checking that public health protocols are followed and waiting for follow-up test results before any restricted areas are returned to normal use.

Officials also said they would issue further updates if there is significant new information. For the time being, the emphasis remains on caution, testing and clear communication with the public. The Ministry said its investigation was continuing.
