Seven outbreaks of disease characterized by a pustular rash and suspected to have been caused by human monkeypox virus were investigated. The outbreaks occurred between February and August 2001 in the province of Equateur in the Democratic Republic of Congo. The outbreaks involved a total of 31 persons and caused five deaths. Specimens from 14 patients were available and were analyzed by electron microscopy, virus isolation, and PCR assays specific for monkeypox virus and varicella-zoster virus. We provide evidence that two outbreaks were indeed caused by monkeypox virus (16 cases, with four deaths), that in two outbreaks both monkeypox and varicella-zoster virus were involved (seven cases, with one death), and that two outbreaks were cases of chickenpox caused by infection with varicella-zoster virus (six cases, with no deaths). In one outbreak, no evidence for either monkeypox or chickenpox was found (two cases, with no deaths).

The outbreak of the monkeypox epidemic underscores the importance of developing a rapid and sensitive virus detection technique. Microneedles (MNs) offer minimally invasive sampling capabilities, providing a solution for the development of integrated extraction and diagnostic portable devices. Here, we report an integrated MNs and hydrogel biosensor (IMHB) platform, composed of an electronic device, an MN patch, and a hydrogel patch.

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.

Background: The current pandemic of 2022 global mpox (formerly known as monkeypox), caused by infection with monkeypox virus (MPXV), has now reached over 120 countries. This constitutes a critical public health issue requiring effective disease management and surveillance. Rapid and reliable diagnosis is conducive to the control of infection, early intervention, and timely treatment.

Herein, we introduced a reversible chemical cross-linking strategy to engineer protein antigens, which can be tracelessly removed upon antigen-presenting cell (APC) uptake and cellular reduction. The chemically cross-linked antigen proteins presented significantly enhanced uptake and epitope presentation by APC.
