Introduction: The epidemiology of Legionella Community-Acquired Pneumonia (L-CAP) in Vallès County during the period 2010-2017 is analysed. Methods and results. The incidence and mortality of L-CAP in Vallès County and in Catalonia during the period 2010-2017 is analysed. In Vallès 569 cases were reported, of which 83.3% ≥ 50 years, and 72.9% in men. The incidence rate (IR) in Vallès (IT 5.47/100 000 inhabitants; 95% CI 5.02-5.92), and especially in Vallès Oriental (IR 7.94/100.000 inhabitants, 95% CI 6.97-8.92) exceeds the rest of Catalonia (IR 3.03/100 000 inhabitants; 95% CI 2.88-3.18). The relative risk (RR) of incidence of L-CAP in Vallès in relation to the rest of Catalonia was 1.80 (95% CI 1.60-1.99). The mortality rate (MR) in Vallès (TM 0.38/100 000 inhabitants; 95% CI 0.24-0.47) exceeds the rest of Catalonia (MR 0.16/100 000 inhabitants; 95%CI 0.13-0.19) with a RR of 3.08 (95% CI 2.03-4.66). Mortality increases with age and cancer. Conclusions. The incidence and mortality of L-CAP in Vallès are higher than the rest of Catalonia. The epidemiological method used is appropriate for analysing the epidemiology of L-CAP and the effectiveness of preventive and control measures
