Legionnaires' disease on symptom onset dates from past outbreaks. In this way, the eventual likely size of an outbreak can be predicted, enabling efficient and effective use of public health resources in managing an outbreak. The first recognized cases of Legionnaires' disease occurred in 1976 in Philadelphia; among more than 2000 attendees of an American Legion convention held at the Bellevue-Stratford Hotel, 182 attendees contracted the disease and 29 of them died. In April 1985, 175 people in Stafford, England, were admitted to the District or Kingsmead Stafford Hospitals with chest infection or pneumonia. A total of 28 people died. Medical diagnosis
Aspiration pneumonia area of consolidation, where liquids accumulate in a particular region of the lung, in alcoholics who aspirate in the supine position. Aspiration pneumonia is typically diagnosed by a combination of clinical circumstances (people with risk factors for aspiration) and radiologic findings (an infiltrate in the proper location). A chest x-ray is typically performed in cases where any pneumonia is suspected, including aspiration pneumonia. Findings on chest x-ray supportive of aspiration pneumonia include localized consolidation depending on the patient's position when the aspiration occurred. For example, people that are supine when they aspirate often develop consolidation in the left lower lobe
