BACKGROUND The coronavirus disease 2019 (COVID-19) pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has affected the maritime sector due to virus transmission onboard and traffic restrictions. However, reports of SARS-CoV-2 transmission on board have been mostly restricted to those occurring on cruise ships. OBJECTIVES To report COVID-19 outbreaks in eight non-cruise vessels and discuss measures to prevent and control the onboard transmission of SARS-CoV-2. METHODS We investigated outbreaks of COVID-19 on vessels anchoring in Baía de Todos-os-Santos, Salvador, Brazil, between February and November 2021. FINDINGS Most vessels were cargo ships that had docked several times before anchoring in Salvador (five had docked in ≥ 9 ports). The crew ranged from 22 to 63 members. The infection attack rate on each vessel ranged from 9.7 to 88.9%. The risk of symptomatic infection largely varied among the crew of each vessel (0 to 91.6%). Overall, the risk of developing COVID-19 signs and symptoms was lower among crew members vaccinated (age-adjusted risk ratio: 0.19; 95% confidence interval 0.06-0.65). SARS-CoV-2 variants not previously identified in Salvador were detected (C.14, B.1.617.2 and B.1.351). MAIN CONCLUSIONS Despite maritime guidelines to avert COVID-19 on board, outbreaks have happened. The multiple stopovers of non-cruise vessels during their routes may contribute to the spread of SARS-CoV-2 variants worldwide. Reducing the onboard transmission of SARS-CoV-2 depends on joint efforts by the crew and local health authorities and, equally important, achieving high vaccination coverage to prevent infections and illness.

Os documentos clínicos, periódicos, relatórios, leis, decretos e imagens ora apresentados referem-se ao Hospício Nacional de Alienados, durante o período em que Juliano Moreira foi seu diretor, além de diretor da Assistência a Alienados do Distrito Federal (1903-1930). O material será reunido na Biblioteca Virtual em Saúde para América Latina e Caribe - História e Patrimônio Cultural da Saúde (com informações sobre diagnósticos, pacientes, terapêuticas e funcionamento do Hospício Nacional) em 2011. O conjunto de fontes oferece elementos para a reflexão sobre a atuação de eminentes psiquiatras cariocas perante a alienação e a sociedade brasileira na Primeira República, quando a psiquiatria nacional se institucionalizava e ganhava apoio estatal.

The article presents a set of clinical documents, periodicals, reports, laws, decrees, and images about the National Asylum for the Insane dating from Juliano Moreira's tenure as its director and as director of Federal District Assistance for the Insane. In 2011, the material will be available at the site of the Virtual Library on Health in Latin America and the Caribbean: Health History and Cultural Heritage. This material, which includes information on diagnoses, patients, treatments, and the operation of the National Asylum, enhances our ability to investigate the activities of eminent psychiatrists in Rio de Janeiro and their attitudes towards "insanity" and Brazilian society under the First Republic, when Brazilian psychiatry was first gaining institutional form and winning government support.
