Blood, Sweat, and Sometimes Tissue Samples: Tracking a Killer Germ
Back to its Watery Birthplace

  • Legionella is often found in freshwater environment, but not in numbers high enough to cause Legionnaire’s disease.
  • It is important to link clinical isolates to environmental samples in cases of Legionnaire’s disease in order to determine the potential source of the disease.
  • Any lab can establish testing for Legionella either as preparedness for outbreaks or for routine surveillance and prevention.
Quote from the Disease Detective

“Working at a local health department provides an amazing opportunity for a CDC LLS Fellow. This experience gives the complete public health picture, from a clinical perspective to population health and big picture investigations.”
