Legionella Pneumonia Following the Heavy Rain Event of July 2018 in Japan

Abstract

We herein report the case of a 62-year-old man diagnosed with Legionella pneumonia while engaged in recovery work in a flooded area after the Heavy Rain Event of July 2018 in Japan. The patient was intubated and maintained on mechanical ventilation and continuous hemodiafiltration. He was also administered antimicrobial therapy with ciprofloxacin and azithromycin. After 53 days in the hospital, he was discharged. It is important to recognize the risk of Legionella infection and to take measures to prevent it during recovery work that involves exposure to water and soil after a flood disaster.
