Mpox is a zoonotic viral disease caused by the (MPXV). Human cases have been mainly restricted to the African continent until the worldwide multi-country outbreak unfolded in 2022. We reconstructed epidemiological links of 53 MPXV infections using genomic epidemiology in Rio Grande do Sul State, southern Brazil, during 2022 and 2023.

Despite the availability of pharmacological prophylaxis for humans and animals, the high genetic diversity of RABV in diverse natural bat hosts and continued circulation in multiple animals pose challenges for effective surveillance. Here, we developed and validated a novel, rapidly deployable amplicon-based sequencing approach for RABV genomic surveillance.

- Western equine encephalitis virus (WEEV) caused a significant outbreak in Argentina and Uruguay from December 2023 to April 2024, with 217 human cases and 2,548 equine cases reported.
- The investigation focused on the Rio Grande do Sul state border area between Argentina and Uruguay, utilizing epidemiologic, entomological, and genomic methods to analyze the outbreak.
- A novel lineage of the virus, proposed as lineage C, was identified in three fatal equine cases, emphasizing the need for ongoing monitoring and equine vaccination to prevent future outbreaks.
Article Synopsis
- A recent outbreak of western equine encephalitis virus (WEEV) has been reported in South America, particularly in Brazil, where three horses have died from the infection.
- Researchers sequenced the WEEV strains and discovered a new lineage responsible for these fatalities.
- To reduce the impact of WEEV, ongoing monitoring and vaccination of horses are essential.
Respiratory Syncytial Virus (RSV) is an important cause of respiratory infection in humans. Severe cases are common in children ≤2 years old, immunocompromised individuals, and the elderly. In 2020, RSV infection reduced in Rio Grande do Sul (RS), southern Brazil; however, in 2021 resurgence of RSV was observed.
