Abstract
Poxviruses are large and diversified viruses that cause an emerging zoonotic disease known as monkeypox (mpox). In the past, mpox predominated primarily in the rural rainforests of Central and West Africa. Recently, the exportation of mpoxv from Africa to other continents has been progressively reported. However, the lack of travel history to Africa in most of the currently reported cases in 2022 promotes the sign of changing epidemiology of this disease. Concerns over the geographic distribution and continued resurgence of mpox is growing. In this review, we addressed the geographic distribution, transmission, reasons for the resurgence of mpox, and vaccination. Although the precise cause of the resurgence in mpox cases is mostly unknown, several suggested factors are believed to be waning immunity, accumulation of unvaccinated people, ecological conditions, risk behaviors of men who have sex with men, and genetic evolution.

Abstract
In May 2022, public health officials noted an unprecedented surge in mpox cases in non-endemic countries worldwide. As the epidemic accelerated, multi-model forecasts of the epidemic's trajectory were critical in guiding the implementation of public health interventions and determining policy. As the case levels have significantly decreased as of early September 2022, evaluating model performance is essential to advance the growing field of epidemic forecasting. Using laboratory-confirmed mpox case data from the Centers for Disease Control and Prevention (CDC) and Our World in Data (OWID) teams through the week of January 26th, 2023, we generated retrospective sequential weekly forecasts (e.g., 1-4-weeks) for Brazil, Canada, France, Germany, Spain, the United Kingdom, the USA, and at the global scale using models that require minimal input data including the auto-regressive integrated moving average (ARIMA), general additive model (GAM), simple linear regression (SLR), Facebook's Prophet model, as well as the sub-epidemic wave (spatial-wave) and n -sub-epidemic modeling frameworks. We assess forecast performance using average mean squared error (MSE), mean absolute error (MAE), weighted interval score (WIS), 95% prediction interval coverage (95% PI coverage), and skill scores. Average Winkler scores were used to calculate skill scores for 95% PI coverage. Overall, the n -sub-epidemic modeling framework outcompeted other models across most locations and forecasting horizons, with the unweighted ensemble model performing best across all forecasting horizons for most locations regarding average MSE, MAE, WIS, and 95% PI coverage. However, many locations had multiple models performing equally well for the average 95% PI coverage. The n -sub-epidemic and spatial-wave frameworks improved considerably in average MSE, MAE, and WIS, and Winkler scores (95% PI coverage) relative to the ARIMA model. Findings lend further support to sub-epidemic frameworks for short-term forecasting epidemics of emerging and re-emerging infectious diseases.

Microbiol Spectr 2023; 11:e0051023. [PMID: 37191553 PMCID: PMC10269760 DOI: 10.1128/spectrum.00510-23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2023] [Accepted: 04/24/2023] [Indexed: 05/17/2023] Open
Abstract
In an increasingly globalized and interconnected world, the outbreak of an infectious disease in one country can become a worrying health emergency for the whole world. A current example is the 2022 monkeypox virus (mpox) outbreak affecting multiple areas across the world. In this context, strategies to interrupt transmission as soon as possible by identifying cases, clusters, and sources of infection should be developed around the world to prevent these crises. The aim of this retrospective and collaborative study was to perform external clinical validation of the VIASURE monkeypox virus real-time PCR detection kit (CerTest Biotec, Spain) with ready-to-use reagents designed for the rapid detection of mpox. A total of 165 samples with suspected infection were used for this analysis. The standard procedures of the clinical microbiology laboratory of the Miguel Servet University Hospital, using the RealStar Orthopoxvirus PCR kit v1.0 (Altona Diagnostics) and bidirectional Sanger sequencing (STAB VIDA, Caparica, Portugal), were considered reference techniques. Furthermore, a subset of 67 mpox-negative samples and 13 mpox-positive samples were routinely tested for clinical diagnosis of other rash/ulcerative pathologies. Accuracy testing resulted in appropriate clinical validation values, as follows: sensitivity, 1 (95% confidence interval [CI], 0.97 to 1); specificity, 1 (95% CI, 0.98 to 1); positive predictive value, 1 (95% CI, 0.93 to 1); negative predictive value, 1 (95% CI, 0.95 to 1). The strength of agreement between assays was almost perfect. The added value is the useful support for the specific diagnosis of mpox infections due to the diagnostic specificity data obtained. IMPORTANCE Given that a large number of mpox outbreaks have been reported worldwide since 2022 in countries in which the disease is not endemic, the main concern for clinicians and global health systems should be to develop effective, available, and easy-to-implement diagnostic strategies to interrupt mpox transmission as soon as possible. This retrospective study demonstrates the satisfactory clinical parameters of a commercially available molecular diagnostic kit for routine testing for mpox in clinical diagnostic laboratories.

Abstract
A 26-year-old man in Australia who has sex with men had severe perianal ulceration, proctitis, and skin lesions develop. Testing revealed primary syphilis, mpox, and primary HIV infection. Recent publications have documented severe mpox associated with HIV infection. Disruption of mucosal integrity by mpox lesions could enable HIV transmission and vice versa.

Abstract
AIM To analyze the characteristics and visibility of the scientific production of monkeypox in dentistry. MATERIALS AND METHODS A bibliometric study was carried out with the publications indexed in the Scopus database up to 22 September 2022. A search strategy was developed using Boolean operators "AND" and "OR," in addition to the MeSH term "monkeypox virus" (MPXV) in the subarea of dentistry. The bibliometric indicators were measured objectively with the SciVal program. RESULTS Of the publications identified, 40% were indexed in first-quartile journals. India and Brazil are the countries with two published papers, while India has more views than the rest. Banaras Hindu University, Varanasi, Uttar Pradesh, India and Dr. Ram Manohar Lohia Hospital, New Delhi, India are the institutions with the highest number of citations with respect to the world average (FWCI: 2.74). The International Dental Journal has a publication on monkeypox in the field of dentistry. India is the country with the most authors (06) who have published about the study. Samaranayake Lakshman Perera is the most productive and high-impact author. CONCLUSION In the area of dentistry, scientific production on monkeypox is still scarce; however, the publications identified are mainly in high-impact indexed journals (Q1 and Q2). It is necessary to prioritize this disease as a line of research, in addition to articulating efforts between dental teams from different institutions. CLINICAL SIGNIFICANCE It is necessary to demonstrate the characteristics of scientific publications on monkeypox in dentistry worldwide in order to have a panoramic view of the dynamics of scientific articles in this area.
