Q fever in Portugal: a one health-oriented literature review. In 1st International Conference of the Zoonoses Working Group. Vila Realhttp://hdl.handle.net/10198/35911Q fever, caused by Coxiella burnetii, is a neglected zoonosis in Portugal, with mandatory notification (1). Transmission to humans occurs mainly by inhalation of contaminated aerosols generated in small-ruminant settings, with shedding peaking around parturition (placenta, bedding, dust) (2 - 4). Evidence from Portugal documents showed animal exposure, peripartum PCR positivity and signals among occupational groups (5-7), but surveillance remains fragmented and methodologies are heterogeneous across studies (5, 4). Regional gaps persist, including in the Portuguese northeastern region (5, 7).porQ feverCoxiella BurnetiiOne HealthZoonosisconference object
