Health officials have confirmed another case of Legionnaires’ disease in a guest who stayed at the Grand Islander by Hilton Grand Vacations in Waikiki.

The fourth case of the disease was diagnosed on April 16, the state Department of Health announced today. The person with the illness is a nonresident Hawaiian who stayed at the hotel from April 16-18. The first case was diagnosed in June 2021, followed by another in early March and a third case on April 2.

“Legionnaires’ disease has the potential to have serious consequences, and we encourage anyone who develops symptoms following a stay at The Grand Islander to contact a physician and the DOH,” said state epidemiologist, the Dr Sarah Kemble, in a statement. “We are encouraged that the Hilton has brought in additional experts and is stepping up efforts to identify potential sources of contamination and treat water sources as a precaution.”

Legionnaires’ disease is a type of pneumonia caused by exposure to Legionella bacteria, which are commonly found in freshwater environments but can be spread through water systems such as showers, sinks, hot tubs and plumbing systems.

It can be treated with antibiotics and cannot be spread from person to person.

Those who have stayed at the Grand Islander and have developed symptoms consistent with Legionella infection are encouraged to seek medical attention and report their illness to the DOH Division of Disease Outbreaks and Control’s Disease Reporting Line at 808-586-4586.
