Unlabelled: The monkeypox virus (MPXV) outbreak, primarily endemic to Africa, has spread globally, with Brazil reporting the second-highest number of cases. The emergence of MPXV in non-endemic areas has raised concerns, particularly due to the co-circulation of other exanthematous viruses such as varicella-zoster virus (VZV) and molluscum contagiosum virus (MOCV). To perform an accurate differential diagnosis of MPXV during the ongoing outbreak in Minas Gerais, Brazil, a 5PLEX qPCR assay targeting orthopoxviruses (OPV), VZV, and MOCV was used to retrospectively analyze all clinical samples that tested negative for MPXV in the initial screening conducted at Funed.

Article Synopsis
  • The Gamma variant of COVID-19, first identified in Brazil, has been linked to higher infection rates, hospitalizations, and fatalities, especially during a surge in Minas Gerais in March-April 2021.
  • A surveillance study analyzed 1,240 COVID-19-positive samples across 305 municipalities, finding that Gamma was the most prevalent variant (71.2%), followed by Zeta (12.4%) and Alpha (9.6%).
  • The study emphasizes the necessity of vaccination to mitigate severe cases and deaths, noting no significant mortality differences among the different variants identified.

Article Synopsis
  • Brazil has experienced high COVID-19 cases and deaths, making Latin America a major pandemic epicenter, with early sustained virus transmission and ongoing gaps in understanding.
  • Researchers analyzed over 17,000 near-complete SARS-CoV-2 genomes from across Brazil and Paraguay, finding multiple viral lineages predominantly imported from Europe before local transmission clusters emerged after November 2020.
  • Effective genomic surveillance has been crucial in tracking the real-time spread of significant variants, such as Gamma (P.1) and Zeta (P.2), and understanding cross-border virus movement into Paraguay.

Article Synopsis
  • - Brazil became a major COVID-19 epicenter in Latin America by May 2021, experiencing high transmission rates and deaths, but gaps remain in understanding how the virus spreads nationally.
  • - The study analyzes nearly complete SARS-CoV-2 genomes from Brazil and Paraguay, revealing that the initial wave was marked by multiple imported viral lineages mainly from Europe, leading to significant local transmission clusters.
  • - As the pandemic progressed without effective restrictions, Brazil saw the emergence and spread of concerning variants like Gamma and Zeta, highlighting the need for extensive genomic surveillance in South America for better pandemic management and public health strategies.

The recent emergence of a coronavirus (SARS-CoV-2), first identified in the Chinese city of Wuhan in December 2019, has had major public health and economic consequences. Although 61,888 confirmed cases were reported in Brazil by 28 April 2020, little is known about the SARS-CoV-2 epidemic in this country. To better understand the recent epidemic in the second most populous state in southeast Brazil - Minas Gerais (MG) - we sequenced 40 complete SARS-CoV-2 genomes from MG cases and examined epidemiological data from three Brazilian states.

Canine visceral leishmaniasis is an important zoonosis in Brazil. However, infection patterns are unknown in some scenarios such as rural settlements around Atlantic Forest fragments. Additionally, controversy remains over risk factors, and most identified patterns of infection in dogs have been found in urban areas.
