Outbreaks of monkeypox (mpox) have historically resulted from zoonotic spillover clade I virus (MPXV) in Central Africa and II MPXV West Africa. In 2022, subclade IIb caused a global epidemic linked to transmission through sexual contact. Here we describe the epidemiological genomic features an mpox outbreak mining region eastern Democratic Republic Congo, by MPXV. Surveillance data collected between September 2023 January 2024 identified 241 suspected cases. Genomic analysis demonstrates distinct lineage divergent previously circulating strains Congo. Of 108 polymerase chain reaction-confirmed cases, median age individuals was 22 years, 51.9% were female 29% sex workers, suggesting potential role for transmission. The predominance APOBEC3-type mutations estimated emergence time around mid-September imply recent sustained human-to-human

The relative contribution of the respiratory route to transmission mpox (formerly known as monkeypox) is unclear. We review evidence for monkeypox virus (MPXV), examining key works from animal models, human outbreaks and case reports, environmental studies. Laboratory experiments have initiated MPXV infection in animals via routes. Some animal-to-animal has been shown controlled studies, sampling studies detected airborne MPXV. Reports real-life demonstrate that associated with close contact, although it difficult infer acquisition individual so far not specifically implicated. Based on available evidence, likelihood human-to-human appears be low; however, should continue assess this possibility.

ABSTRACT Background Monkeypox virus (MPXV) attracted global attention in 2022 during a widespread outbreak linked primarily to sexual contact. Clade I MPXV is prevalent Central Africa and characterized by severe disease high mortality, while II confined West associated with milder illness. A IIb emerged Nigeria 2017, protracted human-to-human transmission forerunner of the B.1 lineage 2022. In October 2023, large mpox Kamituga mining region Democratic Republic Congo (DRC), which we conducted an investigation. Methods Surveillance data hospital records were collected between 2023 January 2024. Blood samples skin/oropharyngeal swabs obtained for molecular diagnosis at National Institute Biomedical Research, Kinshasa. genomes sequenced analyzed using Illumina NextSeq 2000 bioinformatic tools. Results The spread rapidly, 241 suspected cases reported within 5 months first case. Of 108 confirmed cases, 29% sex workers, highlighting contact as key mode infection. Genomic analysis revealed distinct Ib lineage, divergent from previously strains DRC. Predominance APOBEC3-type mutations estimated time emergence around mid-September suggest recent transmission. Conclusions Urgent measures, including reinforced, expanded surveillance, tracing, case management support, targeted vaccination are needed contain this new pandemic-potential outbreak.

Mpox, formerly known as Monkeypox, is a viral zoonotic disease endemic to Central and West Africa that has posed significant public health challenges since its identification in 1970. Despite decades of experience managing outbreaks, the 2022-2024 Mpox outbreaks exposed substantial gaps global preparedness response, leading World Health Organization (WHO) declare Public Emergency International Concern (PHEIC) 2022. The resurgence cases Europe 2022 more recent emergence virulent clade Ⅰb Democratic Republic Congo (DRC) 2024 have highlighted critical need for improved proactive response strategies curb epidemic. This narrative review examines historical epidemiology explores factors limited effective management. These include objective influences such mutations, transmission patterns, environmental changes like deforestation, well subjective factors, including delayed responses, vaccine availability, cessation smallpox vaccinations, inequitable access healthcare. In particular, emphasizes ongoing disparities equity, wealthier nations been able secure vaccines therapeutics quickly, while regions continue struggle with resources. also discusses how socio-economic cultural combined weak infrastructure inadequate surveillance systems, perpetuate cycles outbreak vulnerable populations. Furthermore, 2024, higher virulence mortality rates among children, particularly rural areas, underscores urgency addressing evolving epidemiological landscape Mpox. these challenges, this recommends strengthening healthcare infrastructure, enhancing ensuring equitable treatments, integrating management into strategies. Global collaboration remains essential provide African countries resources support needed manage prevent future effectively. Without measures, world risks prolonged crisis far-reaching consequences both community.

Accurate and early diagnosis of monkeypox virus (MPXV) is crucial for controlling epidemics treating affected individuals promptly. This study aimed to assess the analytical clinical performance MolecisionTM Monkeypox Virus qPCR Assay, Biorain ddPCR MAGLUMI® Ag (chemiluminescence immunoassay, CLIA) Assay. Additionally, it compare application antigen nucleic acid assays offer insights into using commercial assay kits. Specimens from 117 patients, serial diluted cell culture supernatant, artificially created positive samples were tested evaluate these kits MPXV diagnostics. The Assay had a limit detection (LoD) 3.89 CCID50/mL, while an LoD 15.55 CCID50/mL. (CLIA) 0.500 pg/mL. accuracy was comparable demonstrated high sensitivity. specificity all three diagnostic specimens with potential cross-reacting substances 100%. In conclusion, this provides valuable assays, supporting efforts mitigate control spread monkeypox.

We used published data from outbreak investigations of monkeypox virus clade I in the Democratic Republic Congo to estimate distributions critical epidemiological parameters. estimated a mean incubation period 9.9 days (95% credible interval [CrI] 8.5-11.5 days) and generation time 17.2 CrI 14.1-20.9 or 11.3 9.4-14.0 days), depending on considered dataset. Presymptomatic transmission was limited. Those estimates suggest generally slower dynamics than IIb. The time-varying reproduction number for be below epidemic threshold first half 2024. However, South Kivu Province, where newly identified subclade Ib has been associated with sustained human-to-human transmission, we an effective above 0.96-1.27).

Abstract Initial investigation into the emerging mpox outbreak of novel clade Ib in eastern Democratic Republic Congo has identified signs sustained human-to-human transmission and epidemiological links to sexual contacts involving female sex workers (FSWs), which have not been observed previous Ia outbreaks. Using mathematical models incorporating age-dependent contact patterns, we quantified role frequent interactions as opposed community dynamics found that this additional mode could explain its increased potential compared with Ia. As globally-circulating IIb transmitted predominantly among men who men, our findings reinforce importance protecting key population groups, specifically FSWs for Ib, controlling ongoing
