Monkeypox is a zoonotic viral disease caused by the monkeypox virus, a member of the genus Orthopoxvirus within the family Poxviridae, which also includes the variola virus. On Aug. 14, 2024, WHO Director-General declared monkeypox outbreak a public health emergency of international concern.
View Article and Find Full Text PDFPurpose Of Review: The 2024 mpox outbreak, primarily driven by the possibly more virulent clade Ib strain, prompted the WHO declaring it a public health emergency of international concern (PHEIC) on August 14, 2024. This review provides essential guidance for clinicians managing mpox cases, as it contrasts the features of the 2024 outbreak with those of the 2022 epidemic to support better clinical decision-making.
Recent Findings: The review highlights significant differences between the 2024 and 2022 outbreaks, including total case numbers, demographic distribution, and fatality rates.

The mpox virus (MPXV) came to global attention with the 2022 global outbreak. Current vaccination and post-exposure prophylaxis against MPXV consists of live vaccinia whole virus-based vaccines including ACAM2000®, JYNNEOS™, and LC16m8 originally developed against smallpox. Here, we analyzed 152 vaccinia-derived peptides we identified by mass spectrometry for homology with MPXV-1 and MPXV-2 sequences to evaluate their potential relevance to MPXV-specific immunity.

Monkeypox (MPOX) is a zoonotic viral disease caused by the Monkeypox virus (MPXV), which has become the most significant public health threat within the genus since the eradication of the Variola virus (VARV). Despite the extensive attention MPXV has garnered, little is known about its clinical manifestations in humans. In this study, a high-throughput RNA sequencing (RNA-seq) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) approach was employed to investigate the transcriptional and metabolic responses of HEK293T cells to the MPXV A5L protein.

We optimized and used a plaque reduction neutralization test (PRNT) with authentic clade IIa MPXV and vaccinia virus to assess antibody responses over 12 months in 8 donors vaccinated with 2 doses of JYNNEOS. One donor previously received the ACAM2000 vaccine; 7 donors were smallpox vaccine-naive.
