Atenção primária à saúde: a maior aliada na resposta à epidemia da dengue no Brasil

Em resposta ao cenário epidemiológico crítico de incidên- cia de casos, hospitalizações e óbitos por dengue, o Ministério da Saúde do Brasil incorporou, ainda em dezembro de 2023, a vacina contra a dengue no Calendário Nacional de Vacinação. Inicialmente, a vacina foi incorporada para crianças e adolescen- tes de 10 a 14 anos (1), faixa etária que concentra o maior número de hospitalizações pela doença depois das pessoas idosas — para quem, no entanto, a vacina não foi liberada pela Agência Nacional de Vigilância Sanitária (Anvisa). Nesse sentindo, o Brasil tornou-se o primeiro país do mundo a disponibilizar a vacina contra a dengue de forma gratuita no serviço público de saúde, juntamente com diversos métodos de controle vetorial.

Decrease in compulsory notifications registered by the Brazilian National Hospital Epidemiological Surveillance Network during the COVID-19 pandemic: a descriptive study, 2017-2020. / Decréscimo nas notificações compulsórias registradas pela Rede Nacional de Vigilância Epidemiológica Hospitalar do Brasil durante a pandemia da COVID-19: um estudo descritivo, 2017-2020.

OBJECTIVE: To describe compulsorily notifiable diseases, health conditions and public health events (DAEs as per the Brazilian acronym) registered by the National Hospital Epidemiological Surveillance Network (RENAVEH as per the Brazilian acronym), before and during the COVID-19 pandemic. METHODS: This was a descriptive ecological study using records held on the Notifiable Health Conditions Information System (SINAN as per the Brazilian acronym) between Epidemiological Week (EW) 1 of 2017 (January 1st, 2017) and 52 of 2020 (December 26, 2020). RESULTS: Between 2017 and 2020, RENAVEH notified 1,258,455 DAE form records, with only 225,081 (17.9%) notifications in 2020, representing a decrease of 146,340 records compared to 2019. The temporal analysis showed a decrease per EW of more than 1,000 notified records with effect from EW 12. CONCLUSION: There was a decrease in compulsorily notifiable DAEs registered by RENAVEH in Brazil taking the period analyzed as a whole, in particular in 2020.

Isolation, genetic and immunohistochemical identification of Toxoplasma gondii from human placenta in a large toxoplasmosis outbreak in southern Brazil, 2018.

The present study aimed to describe a molecular analysis of environmental and pork samples, the isolation, genetic identification and immunohistochemistry (IHC) of Toxoplama gondii from placenta and amniotic fluid from five pregnant women that miscarried during a toxoplasmosis outbreak in 2018, Santa Maria, Rio Grande do Sul. Environmental and pork samples were submitted to polymerase chain reaction (PCR); placenta and amniotic fluid samples to histopathology, IHC, mouse bioassay and PCR. All samples were genotyped by PCR-RFLP with 11 loci. Histopathologic and IHC were compatibles with toxoplasmosis. All pregnants were positive in PCR and bioassay, the genotypes were compared, and all were equal suggesting a same source of infection. Among the environmental and food samples, a sludge sample from a water tank and two porks samples were positive in PCR, and the genotypes were different from the pregnant women isolates. It is concluded that obtain and compare isolates is essential to elucidate outbreak source.

Isolation and molecular characterization of Toxoplasma gondii from placental tissues of pregnant women who received toxoplasmosis treatment during an outbreak in southern Brazil.

Toxoplasma gondii is a protozoan that has great genetic diversity and is prevalent worldwide. In 2018, an outbreak of toxoplasmosis occurred in Santa Maria, Brazil, which was considered the largest outbreak ever described in the world. This paper describes the isolation and molecular characterization of Toxoplasma gondii from the placenta of two pregnant women with acute toxoplasmosis who had live births and were receiving treatment for toxoplasmosis during the outbreak. For this, placental tissue samples from two patients underwent isolation by mice bioassay, conventional PCR and genotyping using PCR-RFLP with twelve markers. Both samples were positive in isolation in mice. The isolate was lethal to mice, suggesting high virulence. In addition, the samples were positive in conventional PCR and isolates submitted to PCR-RFLP genotyping presented an atypical genotype, which had never been described before. This research contributes to the elucidation of this great outbreak in Brazil.

Molecular characterisation of the emerging measles virus from Roraima state, Brazil, 2018.

Measles is a human infectious disease of global concern that is caused by the measles virus. In this study, we report the complete genome sequencing of one measles virus isolate, genotype D8, that was obtained directly from a urine sample in Boa Vista city, the capital of Roraima state in Brazil. Phylogenetic reconstruction grouped the genome described in this study with that of samples from Australia, South Korea, and Italy. To our knowledge, this is the first complete genome sequence of a wild-type measles virus reported from Latin America. Therefore, the present data strengthen the current knowledge on the molecular epidemiology of measles worldwide.

Measles outbreak: preliminary report on a case series of the first 8,070 suspected cases, Manaus, Amazonas state, Brazil, February to November 2018.

We report an ongoing measles outbreak in Manaus, Amazonas state, Brazil. As at 3 November 2018, 1,631 cases were confirmed corresponding to an incidence of 75.3 per 100,000 inhabitants; all five sanitary districts presented confirmed cases. Reintroduction of measles virus in Manaus is likely related to the current outbreak in Venezuela and due to recent decline in measles vaccine coverage. Given the current scenario, prevention and control measures should target individuals aged 15-29 years.

Análise do Sistema de Informação da Vigilância de Eventos Adversos Pós-Vacinação no Brasil, 2014 a 2016

[RESUMO]. Objetivo. Descrever as características das notificações de eventos adversos pós-vacinação (EAPV) no Sistema de Informação da Vigilância de EAPV (SI-EAPV) on-line nos primeiros 2 anos de operação do sistema. Método. Foi realizado um estudo descritivo dos registros de EAPV notificados no SI-EAPV entre julho de 2014 e junho de 2016. Resultados. Durante o período do estudo, foram registradas 24 732 notificações. De 5 570 municípios brasileiros, 2 571 (46,2%) realizaram notificação de algum EAPV. Entretanto, somente 1 622 (6,6%) notificações estavam encerradas no momento do estudo; dessas, 89,9% não apresentaram gravidade. Entre as notificações encerradas, 19,7% não tiveram o preenchimento da variável “atendimento médico” e 98,7% não apresentaram registro de exames laboratoriais. As manifestações clínicas sistêmicas neurológicas foram as mais frequentes entre os eventos adversos graves encerrados, correspondendo a 59,5% dos sinais e sintomas. Em relação à idade, os maiores coeficientes de notificação foram registrados entre os menores de 4 anos. Conclusão. O SI-EAPV mostra-se útil no monitoramento da segurança das vacinas. Contudo, os municípios precisam ampliar a adesão ao sistema, bem como realizar as investigações e notificações dos EAPV, preenchendo a ficha de notificação de forma adequada e oportuna. O conhecimento sobre EAPV pode ser aplicado na prática dos serviços de vigilância em saúde, melhorando a segurança de utilização dos imunobiológicos.

[ABSTRACT]. Objective. To describe the characteristics of vaccine adverse events (VAE) reports in the online VAE Reporting System (VAE-RS) after 2 years of operation. Method. A descriptive analysis of VAE reports entered into the VAE-RS between July 2014 and June 2016 was performed. Results. During the study period, 24 732 VAE were reported. Of 5 570 Brazilian municipalities, 2 571 (46.2%) reported at least one VAE; however, only 1 622 (6.6%) reports had been completed/closed at the end of the study period. Of these, 89.9% referred to mild VAE. Among the completed reports, 19.7% did not provide information on “type of medical care provided,” and 98.7% had no information regarding laboratory tests. Systemic neurological symptoms were the most frequent serious VAE among closed reports (59.5% of serious signs/symptoms). Concerning age, the highest VAE reporting coefficients were recorded for children aged ≤ 4 years. Conclusion. The VAE-RS is useful to monitor immunization safety. However, municipal services must increase adherence to the system and perform the required investigation and reporting of VAE, with timely and adequate completion of the VAE-RS form. Knowledge regarding VAE can be used in the daily routine of surveillance services, improving the safety of immunobiological agents.
