“…In other words, the present study is consistent with some previous reports, suggesting that seroprevalence for C. burnetii among professionals working with animals or involved in meat processing may be up to 50% [1,6,7,10,16,19,[38][39][40], largely exceeding estimates in non-occupationally exposed individuals from the index areas (where prevalence estimates ranging between 13.6% and 14.3% were retrieved) [13,25], and national figures for non-occupational exposed individuals [6,19,37,41,42]. In this regard, it should be stressed that according to official reports, between 2015 and 2021, a total of 17 cases of QF have been reported to Italian health authorities, for an annual reference rate well below 0.1 cases per 100,000 persons [23,24].…”

“…In fact, not only do pooled estimates substantially mirror several international reports on this pathogen [1,6,7,10,16,19,38,39,41,44], but they are also quite consistent with some previous Italian reports, where the relatively high occurrence of this pathogen in various agricultural settings was highlighted [20,45]. For example, by 1992, 13.1% of 99 sampled farms, 4.4% of sampled animals, and 6.5% of raw milk samples from the Apennine region of Emilia Romagna were contaminated by C. burnetii [20].…”

Coxiella burnetii (C. burnetii) can cause a serious human disease known as Q Fever (QF). Our study summarized seroprevalence data from occupational settings in Italy, a country characterized by low notification rates of QF (17 cases between 2015 and 2021). Through systematic research on 3 databases (PubMed, EMBASE, MedRxiv), all studies including seroprevalence rates of C. burnetii in Italy were retrieved, and their results summarized and compared. We identified a total of 7 articles for a total of 1178 workers, mostly from agricultural settings. A pooled seroprevalence of 44.0% (95% Confidence Interval [95%CI] 27.6 to 61.8) was calculated. Subgroup estimates ranged from 2.8% (95%CI 0.9–6.3) in forestry rangers to 49.2% (95%CI 26.8–72.0) in livestock farmers, and peaked at 73.7% (95%CI 56.9–86.6) and 75.9% (95%CI 13.4–98.5) in abattoir workers and veterinary professionals, respectively. Seroprevalence rates for C. burnetii largely exceeded the official notification rates, suggesting its substantial underreporting in Italy.

“…In Portugal, only one wild mammal molecular prevalence study has been performed, but red deer and wild boar were negative to C. burnetii [ 6 ]. Other studies performed in Portugal have reported Q fever in domestic ruminants [ 6 , 37 , 38 , 39 , 40 ], dogs and cats [ 41 ], and humans [ 42 , 43 , 44 , 45 ]. Nevertheless, this study is the first report of C. burnetii antibodies in red deer and wild boar in east–central Portugal.…”

Q fever is caused by the pathogen Coxiella burnetii and is a zoonosis that naturally infects goats, sheep, and cats, but can also infect humans, birds, reptiles, or arthropods. A survey was conducted for the detection of antibodies against C. burnetii in a sample of 617 free-ranging wild ruminants, 358 wild boar (Sus scrofa) and 259 red deer (Cervus elaphus), in east–central Portugal during the 2016–2022 hunting seasons. Only adult animals were sampled in this study. Antibodies specific to C. burnetii were detected using a commercial enzyme-linked immunosorbent assay (ELISA; IDVet®, Montpellier, France) according to the manufacturer’s instructions. The seroprevalence of C. burnetii infection was 1.5% (n = 9; 95% confidence interval [CI]: 0.7–2.8%). Antibodies against C. burnetii were detected in 4/358 wild boar (1.1%; 95% CI: CI: 0.3–2.8%) and 5/259 red deer (1.9%; 0.6–4.5%). Results of the present study indicate that antibodies against C. burnetii were present in wild boar and red deer in Portugal. These findings can help local health authorities to focus on the problem of C. burnetii in wildlife and facilitate the application of a One Health approach to its prevention and control.

“…A large outbreak of Q fever has already been described in Europe, more precisely in the Netherlands, triggered by sheep, and since then animal soroprevalence and occupational infections have been described in nearby countries [ [16] , [17] , [18] ]. In South America, studies carried out in Brazil, Argentina, Chile and French Guiana have pointed to the soroprevalence of the agent in animal herds and human populations, highlighting the possibility that other countries on the continent are being affected by the disease, such as Paraguay, which until now had no reports of human or animal infection [ [19] , [20] , [21] , [22] ].…”
