The literature on Legionnaires’ disease (LD) widely cites 2 to 10 days (less frequently to 14 days) as the incubation period for the disease. This chapter summarizes the findings of reports with data adequate to examine the potential for incubation periods longer than 10 to 14 days. These findings suggest that while the majority of cases will develop by 14 days, 19 days may be the upper end of the incubation period. The scientific literature was searched, primarily via PubMed and Scirus, for reports on outbreaks of LD. The recovered reports were reviewed for information on the incubation period considered for case inclusion and for data on the actual periods between exposure and symptom onset for the cases. Investigators of outbreaks with well-defined sources and exposure windows should consider a longer case inclusion period from 14 to perhaps as long as 21 days to ensure good data capture and to help better define the latency period between exposure and symptoms for LD.
