Decrease in compulsory notifications registered by the Brazilian National Hospital Epidemiological Surveillance Network during the COVID-19 pandemic: a descriptive study, 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.

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.

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.

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.

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.

[Analysis of the Vaccine Adverse Event Reporting System in Brazil, 2014 to 2016Análisis del Sistema de Información de Vigilancia de Eventos Adversos Posvacunación en Brasil, 2014 a 2016].

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.
