Article Synopsis
  • The study explores the resurgence of Oropouche fever in Brazil from 2023 to 2024, focusing on virological factors influencing the outbreak after decades of sporadic cases.
  • Researchers gathered data from various sources, analyzed serum samples from patients and previously infected individuals, and performed molecular tests to understand the virus's characteristics and behavior.
  • The findings showed an extraordinary spike in cases in 2024, with over 8,600 confirmed incidents, highlighting the virus's widespread distribution across all regions of Brazil.

Background: Oropouche fever, an orthobunyavirus disease endemic in Brazilian Amazon, has caused many febrile epidemics. In 2024, an epidemic of Oropouche fever spread in Brazil, with more than 7930 cases reported between Jan 1 and Aug 31. Infections in pregnant people have suggested the possibility of negative fetal consequences, therefore we tested newborns with microcephaly for known congenital pathogens and Oropouche virus (OROV).

Article Synopsis
  • A study conducted in France during the 2023-24 RSV season analyzed the effectiveness of nirsevimab, a monoclonal antibody, in preventing RSV infections in infants, focusing on breakthrough cases.
  • Out of 695 RSV-infected infants, researchers sequenced the full-length RSV genome of 545 infants, identifying that 48% had breakthrough infections despite receiving nirsevimab.
  • While no resistance was found in RSV-A infections from nirsevimab-treated infants, two cases of RSV-B showed substitutions linked to resistance, indicating a potential concern for the antibody's effectiveness against this variant.

Adjunctive linezolid versus clindamycin for toxin inhibition in β-lactam-treated patients with invasive group A streptococcal infections in 195 US hospitals from 2016 to 2021: a retrospective cohort study with target trial emulation.

Lancet Infect Dis

October 2024

Clinical Epidemiology Section, Critical Care Medicine Department, National Institutes of Health Clinical Center, Bethesda, MD, USA; Critical Care Medicine Branch, National Heart Lung and Blood Institute, Bethesda, MD, USA. Electronic address:

Background: Adjunctive clindamycin use is associated with survival in invasive group A streptococcus (GAS) infections but increasing clindamycin resistance in GAS has called into question its durability for this indication. Linezolid also inhibits GAS toxin and virulence factor production, but clinical efficacy data remain sparse.

Methods: We retrospectively emulated a target multicentre, non-blinded, non-inferiority trial to assess the efficacy of adjunctive linezolid compared with clindamycin in adult inpatients with invasive GAS infection treated with a β-lactam using the PINC AI database between 2016 and 2021.

Safety, immunogenicity, and optimal dosing of a modified vaccinia Ankara-based vaccine against MERS-CoV in healthy adults: a phase 1b, double-blind, randomised placebo-controlled clinical trial.

Electronic address:

Article Synopsis
  • MERS-CoV is a serious respiratory virus with a high mortality rate and currently no licensed vaccines, prompting research into a candidate vaccine called MVA-MERS-S, which uses a modified vaccinia virus.
  • A phase 1b clinical trial was conducted with healthy volunteers (ages 18-55) across Germany and the Netherlands to evaluate the safety and immunogenicity of MVA-MERS-S, testing various dosing schedules and comparing it to a placebo group.
  • The trial involved 244 screened participants, with 140 randomly assigned to different dosing regimens, and the outcomes focused on both the safety of the vaccine and the resulting immune response measured through antibody levels and seroconversion rates.

Article Synopsis
  • - Human African trypanosomiasis is a severe neglected tropical disease that can be fatal without treatment, and the WHO has updated its treatment guidelines after a thorough review.
  • - Fexinidazole is now the preferred first-line treatment for patients aged 6 years and over who weigh at least 20 kg, eliminating the need for invasive lumbar punctures for staging the disease.
  • - While fexinidazole improves treatment options and reduces the risk of severe side effects from previous medicines, it remains unavailable for children who don't meet the age or weight criteria, making interim use of pentamidine necessary in some cases.

Article Synopsis
  • There is a pressing need for new treatments for serious infections caused by Gram-negative bacteria, which the REVISIT study examined by evaluating aztreonam-avibactam against standard treatments in complicated infections.
  • The study involved a multinational, open-label design with adults who had complicated intra-abdominal infections or hospital-acquired pneumonia, comparing aztreonam-avibactam with meropenem or colistin over 5-14 days.
  • Results showed that out of 422 enrolled patients, 64% had identified Gram-negative pathogens, and the study aimed to determine clinical cure rates and safety without formal hypothesis testing.
