Infectious disease experts alarmed by Legionella at Bay Area hospital
SFGATE • • health
Key Points:
- Kaiser Permanente Santa Clara identified Legionella bacteria during routine monitoring, though the contamination source is still unknown; most patients are recovering at home, and the facility remains safe and operational.
- Legionella bacteria naturally occur in water and spread through inhaling contaminated mist, often from large plumbing and air conditioning systems, causing Legionnaires’ disease, a severe pneumonia with respiratory and gastrointestinal symptoms.
- The hospital reported 18 cases, which infectious disease experts find unusually high for a healthcare setting, raising concerns due to the vulnerability of hospitalized and immunocompromised patients.
- Symptoms of Legionnaires’ disease can mimic other pneumonias, making diagnosis challenging; awareness of the outbreak is critical for healthcare providers to consider Legionella in patients with pneumonia-like symptoms.
- Kaiser has implemented additional water treatment and preventive measures while continuing water system testing in collaboration with public health authorities to control the bacteria and prevent further illness.
