Nosocomial Mycobacterium tuberculosis transmission among healthcare students in a high incidence region, in Vitória, State of Espírito Santo

Abstract: This open comparative study for evaluating hypersensitivity to tuberculin among medical students (n=441), nursing students (n=178) and economics students (n=230) in Vitória, State of Espírito Santo, had the aim of assessing whether the prevalence of positive tuberculin tests among healthcare students could be used as a sentinel event for nosocomial transmission in localities with high endemicity. There was a significant change in the frequency of purified protein derivative reactivity in the nursing students (… Show more

“…In a study among medical students at a university in Rio de Janeiro, Silva et al 17 found a positive booster effect in 1.3%. This was similar to the result from Maciel et al, 7 with a positive booster effect in 1%, among groups of medical, nursing and economics students at a university in Espírito Santo. Although this last study 7 was also carried out in the state of Espírito Santo, we cannot make the inference that those results from analysis of the booster effect could be extrapolated to our sample.…”

“…Some studies 3,6,7,9,10,13,17,18,a have dealt with healthcare professionals' risk of infection and becoming ill with Mycobacterium tuberculosis. However, in Brazil, only one study has looked into this risk among community health agents (CHAs).…”

“…Considerando-se os grupos de risco para IL-TB, os profissionais da área da saúde estão entre os mais vulneráveis, como demonstram várias publicações 12,13,14,15,16,17,18,19,20 . Uma revisão sistemática encontrou que a incidência de ILTB, demonstrada por meio da conversão da prova tuberculínica (PT), pode chegar a 14% nesses profissionais, e o risco de evoluir para TB doença é de 5.361 casos/100 mil profissionais de saúde a cada ano, em virtude da exposição nosocomial 21 .…”

“…Entretanto, com a crescente tendência de haver maior proporção de infectados no decorrer dos períodos, levantou-se a hipótese de estar ocorrendo viragem tuberculínica neste tempo de práticas ambulatoriais e hospitalares mais frequentes, como demonstrado por outros autores 15,17 . Os dados da literatura sugerem que a incidência da infecção pelo Mycobacterium tuberculosis em estudantes de medicina, não difere de países com baixa incidência da doença 30,31 . Este estudo mostrou a vulnerabilidade desta população em relação à TB e revelou a necessidade de implementação de programas de biossegurança para os estudantes de medicina, além de alertar para o uso de medidas de controle, incluindo isolamento respiratório de casos confirmados ou suspeitos de TB e a proteção respiratória individual durante o atendimento ao paciente infectado.…”
