Two of the 186 persons (1%) with acute Q fever examined in this study were 80 years of age or older. Both were males and both had Coxiella burnetti pneumonia. Q fever was not suspected during their hospital stay and would not have been diagnosed if these patients had not been part of a prospective study of community-acquired pneumonia.
