Today at the 64th Annual Epidemic Intelligence Service (EIS) Conference hosted by the CDC, Amanda Kamali, MD will lead a discussion about nosocomial Legionella infections.
Dr. Kamali discussion will focus on the idea that “current investigation practices for hospital-associated Legionella infection may not be enough to detect and prevent future cases.”
In European hospitals, testing for Legionella in water systems is required quarterly; in the US, however, the CDC only requires hospitals to test if there is an outbreak (2 or more confirmed cases) or one transplant unit case.
The EIS looked at Legionellosis surveillance data from LA County for October 2005-August 2014 and found that among the nosocomial cases, 72.8% were definite nosocomial cases and 27.2% were identified as possible nosocomial. 15% of the definite cases were followed by additional cases at the same facility. Because of this, Dr. Kamali concludes that it would be important to conduct preventive environmental testing for Legionella after one confirmed case.
