This study examines the epidemiological and genomic characteristics, along with the transmission dynamics, of SARS-CoV-2 within prison units I and II in Campo Grande, Mato Grosso do Sul, Brazil. Conducted between May and October 2022, it reveals how the virus spreads in the confined settings of prisons, emphasizing the roles of overcrowded cells, frequent transfers, and limited healthcare access. The research involved 1927 participants (83.

- * A cross-sectional approach was used, enrolling 1,138 individuals over nearly two years, with tests revealing a 20% prevalence of IgM antibodies and a remarkable 97.5% for IgG antibodies against HSV-1.
- * The presence of HSV-1 DNA was confirmed in over a quarter of individuals with positive IgM results, indicating a significant silent prevalence of the virus within this community, particularly in individuals with certain urinary and genital symptoms.
Article Synopsis
- The rising spread of arboviruses and increasing infection rates emphasize the urgent need for improved methods to rapidly and accurately detect these pathogens.
- This study focuses on combining nanopore sequencing with reverse transcription polymerase chain reaction (RT-PCR) to create a multiplex RT-PCR protocol.
- The new protocol allows the simultaneous detection of multiple viruses, including Chikungunya, dengue, Zika, yellow fever, and West Nile, enhancing our ability to differentiate between arbovirus strains effectively.
This study assessed the seroprevalence of SARS-CoV-2 in 496 asymptomatic individuals from Mato Grosso do Sul, located in Dourados, the largest periurban indigenous area in Brazil, from January 25 to February 4, 2021. The volunteers participated before receiving their first dose of the CoronaVac inactivated vaccine. For screening, blood samples were collected and analyzed using SARS-CoV-2 rapid tests and the enzyme-linked immunosorbent assay (ELISA).

- * Collaborative efforts led to the collection of 422 chikungunya virus genomes from 12 states, offering insights into how the virus has spread and evolved across the country.
- * Analysis of the genetic data revealed two distinct subclades of the virus and highlighted Northeast Brazil as the main spreading region, with immune system factors potentially influencing its genetic diversity.
Article Synopsis
- Mosquito-borne diseases like Yellow Fever, Zika, Chikungunya, and Dengue are causing big health problems in Brazil, especially since Chikungunya started spreading in 2014.
- In two years (2021-2022), scientists created 422 new virus genomes from 12 states to better understand how Chikungunya spreads, as there were over 312,000 reported cases.
- They discovered that the northeast region of Brazil is the main area where the virus is spreading to other places and found that certain factors in the immune system might be changing the virus's genes in Brazil.
There is a scarcity of studies on the prevalence of Trichomonas vaginalis (TV) in indigenous populations of Brazil. We conducted a cross-sectional study between January and December 2018, on indigenous women living nearby an urban center of the Midwest region of Brazil and determined the prevalence of TV. Factors associated with TV infection and a comparison of molecular and direct microscopy diagnoses were determined.
