Four more people have contracted Legionnaires’ disease after visiting The Guest House at Graceland hotel in Memphis, TN, increasing the total to nine, the Shelby County Health Department (SCHD) said in a statement.

The hotel’s hot tub and swimming pool both tested positive for Legionella bacteria, which causes Legionnaires’ disease. The aquatics center, which includes the hot tub and pool, was closed June 26 for remediation but reopened Wednesday after testing returned negative results for Legionella.

Anyone who stayed at or visited the hotel between May 12 and June 26 and has experienced or is still experiencing pneumonia- or flu-like symptoms should contact the SCHD Hotline at (901) 222-9299 and seek immediate medical attention.

In related news, a lawsuit was filed against the hotel’s owner, Elvis Presley Enterprises, Inc., on behalf of one victim. The lawsuit is seeking compensation for Douglas Johnson of Miami Lakes, FL, and his wife, Marisol, whose relationship with her husband was allegedly harmed by the illness.
