Psitacose e Saúde Ocupacional

Introduction/framework/objectives Psittacosis is a rare entity caused by Chlamydophila psittaci. This bacterium is transmitted through contact with contaminated birds, namely psittaciformes, which include parrots, macaws and parakeets, as pigeons and chickens. The objective of this work is to highlight the pathology and the role of Occupational Health in it. Methodology A bibliographic search was carried out on original articles published in Portuguese and English, in June 2022, in the PubMed and Cochrane Library databases, using the keywords “Psittacosis”, “Occupational exposure” and “Occupational health”. Three articles were also included, not covered by the research, relevant to the work, for reporting the Portuguese reality. Contents Outbreaks can occur in workers with occupations that involve contact with live birds or carcasses, such as veterinarians, breeders, or pet store workers. However, it is difficult to establish the precise incidence and prevalence of psittacosis, probably due to the lack of routine screening. Transmission occurs mainly by aerosols, inhalation of urine, feces or other contaminated particles; transmission between humans, although possible, is rare. The incubation period ranges from five to 14 days, but may extend to weeks in cases of subacute or latent infection. It has a clinical presentation like a flu-like syndrome and can cause disseminated and even potentially fatal disease. The most frequent findings on chest radiography are segmental or lobar consolidation, especially in the lower lobes. It can occasionally cause marked leukocytosis, c-reactive protein (CRP) is often elevated, and liver enzymes change in approximately half of hospitalized patients, with elevation of aspartate aminotransferase (AST) and low serum albumin levels. Tetracyclines are the drug of choice for treatment. Discussion and Conclusions Although the number of cases is apparently small, the impact of the disease is most likely underestimated. Thus, it is necessary to increase the awareness of this pathology both for Occupational Health professionals and for employers and workers themselves. On the other hand, an approach is needed that encompasses collaboration between human and animal health agencies, laboratories and medical and veterinary professionals, for timely surveillance, reporting and treatment. Thus, anamnesis and early recognition of the epidemiological context are extremely important, with a view to diagnosing and instituting appropriate therapy. In addition, occupational risk factors and exposure control among workers should be considered to prevent transmission in the workplace.
