Initially 3 cases were identified, and this led them to the hot tub. Through proceeding to survey past guest, 92 cases were identified, including nine laboratory-confirmed (urinary antigen positive) cases, 19 probable (self-reported pneumonia) cases, and 64 suspected (self-reported fever and ≥1 compatible symptom*) cases. Of these, 70 had required medical care, and 16 people were hospitalized and there was one reported death.
Not the way to meet up with Elvis after going into a Memphis hotel hot tub, or any hotel water for that matter. But how do you know? In this case, "environmental health specialists conducted an assessment of the hotel aquatics facility and identified improper water treatment monitoring and low chlorine residuals (0 ppm; acceptable range = 1–3 ppm)." "Laboratory testing of the aquatics facility water samples identified three Legionella polymerase chain reaction–positive samples from the pool, pool sand filter, and hot tub sand filter, and isolated Legionella pneumophila serogroup 1 from the hot tub sand filter." Something to be said about that smell of chlorine when poolside.
