Background
Health care workers (HCWs) have a high risk of infection with coronavirus disease 2019 (COVID-19), especially those treating patients with confirmed or suspected diagnosis (front-line).
Aim
To evaluate the incidence and prevalence of the COVID-19 infection among HCWs and to analyse the risk factors and the clinical characteristics among infected ones.
Methods
Observational, retrospective, single-center study (Centro Hospitalar e Universitário de Coimbra, Portugal). Data were collected from March 1 to June 30, 2020.
Findings
Overall, 211 (2.63%) out of 8037 HCWs were diagnosed with COVID-19. Most of the infections occurred during the early stage of disease outbreak. Among the infected HCWs, only 20.9% (n=44) were from the front-line. Both front-line and non-front-line HCWs were exposed primarily to patients (48.6% in both groups), but the non-front -line were (presumably) more infected by colleagues (10.8% vs 24.8%,
p
=0.04). Front-line HCWs performed more family isolation than non-front -line (88.9% vs 82.5%,
p
>0.05) and presumably less family members were infected in the former group (19.4% vs 26.3%,
p
>0.05). The proportion of HCWs with asymptomatic infection was statistically significantly lower in the front-line group (2.4% vs 19.9%,
p
=0.05).
Conclusion
The prevention and control actions implemented were effective in mitigating the COVID-19 outbreak; HCW infections occurred mainly in the early stages. Non-front -line HCWs were at a higher risk, warranting specific attention and interventions targeting this group.
Resumo Analisa a formação do médico Antônio Luis Cavalcanti de Albuquerque de Barros Barreto, com passagens pela Faculdade de Medicina do Rio de Janeiro e pelo Instituto Oswaldo Cruz, bem como sua atuação na divulgação do projeto da Fundação Rockefeller no Brasil. A partir de testamento, relatos orais, tese de doutoramento e notícias de jornais, é possível compreender as especificidades da turma de 1913 do Curso de Aplicação do Instituto Oswaldo Cruz e como seus estudantes estiveram articulados em ações relativas ao projeto de saúde internacional. O texto evidencia que a defesa dos acordos com a Fundação Rockefeller podia causar controvérsias, negociações e concessões em estados onde ela ainda não havia penetrado, como ocorreu em Pernambuco.
Resumo O artigo discute a influência da formação de jovens sanitaristas na Fundação Rockefeller para as ações que desenvolveram nos cargos de chefia sanitária no Brasil. São apresentados os métodos de educação e propaganda sanitárias da instituição norte-americana e os cartazes elaborados sob orientação do médico Antônio Luis Cavalcanti de Albuquerque de Barros Barreto na Reforma Sanitária da Bahia. Após retornar da Universidade Johns Hopkins, em Baltimore, onde foi bolsista da Rockefeller entre 1921 e 1922, o médico contribuiu para a difusão nacional dos conhecimentos adquiridos internacionalmente.
