Em termos de vulnerabilidade social, a má comunicação foi produtora de desinformação e estigma. O surgimento de falhas na atenção integral à saúde na rede disponível resultou em vulnerabilidade programática. Implicações clínicas e sociais para o exercício da prática profissional em Enfermagem foram manifestadas, diante da necessidade de melhoria no manejo clínico e na conduta empática dos profissionais de enfermagem no atendimento aos homens gays e bissexuais. Conclusão: Ser homem gay e bissexual condicionou à experiencia da vulnerabilização no contexto do surto da Mpox no Brasil, afetando-os de maneira multidimensional. (AU)

Objective: to analyze the phenomenon of health vulnerability based on the experience of adult gay and bisexual men living in Brazil in the face of the Mpox epidemic outbreak. Methods: Qualitative, national study, carried out with 67 adult gay and bisexual men, living in Brazil. A web-survey was carried out, the data of which was subjected to Reflective Thematic Content Analysis, interpreted using the theoretical/conceptual framework of Social Vulnerability. Results: sexual diversity was conditioned by the transmission of mpox, producing individual vulnerability in gay and bisexual men. In terms of social vulnerability, poor communication produced misinformation and stigma. The emergence of gaps in comprehensive health care in the available network resulted in programmatic vulnerability. Clinical and social implications for the exercise of professional nursing practice were expressed, given the need to improve clinical management and the empathetic conduct of nursing professionals when caring for gay and bisexual men. Conclusion: being a gay and bisexual man led to the experience of vulnerability in the context of the Mpox outbreak in Brazil, affecting them in a multidimensional way. (AU)

Ações contra monkeypox em unidade de urgência e emergência: relato de experiência / Actions against monkeypox in a urgency and emergency unit: experience report / Acciones contra la viruela del mono en una unidad de urgencias y emergencias: reporte de experiencia

A monkeypox, ou mpox, consiste em uma nova problemática em saúde pública, que exige ações imediatas para seu controle. Diante disso, este relato de experiência visou relatar as fragilidades nas ações de controle da monkeypox em unidades de urgência e emergência em Fortaleza, Brasil, de 10 de agosto a 20 de novembro de 2022. Utilizou-se a análise temática para organização das categorias nos resultados e o referencial teórico da racionalidade limitada de Herbert Simon para discussão. Duas categorias surgiram: capacitação para identificação e manejo de monkeypox pelos profissionais de saúde; e desafios nas ações contra monkeypox em unidades de pronto atendimento. Apesar de ações iniciais significativas para contenção da doença, ainda há fragilidades na capacitação de recursos humanos, na vigilância em saúde e na qualidade da detecção de casos, que podem impactar o controle da doença e aumentar sua infectividade, morbidade e mortalidade futura.

Monkeypox or mpox configures a new public health problem that requires immediate action to control it. Thus, this experience report aimed to describe weaknesses in control actions against monkeypox in urgency and emergency units in Fortaleza, Brazil, from August 10 to November 20, 2022. Thematic analysis was used to organize the categories in results and in the theoretical framework of Herbert Simon's Limited Rationality for discussion. Overall, two categories emerged: Training so healthcare providers can identify and manage monkeypox and Challenges in actions against the disease in emergency care units. Despite significant initial actions to contain the disease, weaknesses remain in the training of human resources, health surveillance, and the quality of case detection, which can impact disease control and increase its future infectivity, morbidity, and mortality.

La viruela del mono es un nuevo problema de salud pública que requiere acciones inmediatas para controlarla. Ante esto, este reporte de experiencia tuvo como objetivo reportar debilidades en las acciones de control contra la viruela del mono en las unidades de urgencias y emergencias en Fortaleza, Brasil, en el período del 10 de agosto al 20 de noviembre de 2022. Se utilizaron el análisis temático para organizar las categorías en los resultados y el marco teórico de la racionalidad limitada de Herbert Simon para la discusión. Surgieron dos categorías: Capacitación para la identificación y manejo de la viruela del mono por parte de profesionales de la salud; y desafíos en las acciones contra la enfermedad en las unidades de urgencias. A pesar de las importantes acciones iniciales para contener la enfermedad, aún existen debilidades en la capacitación de los recursos humanos, la vigilancia de la salud y la calidad de la detección de casos, que pueden impactar el control de la enfermedad y aumentar su infectividad, morbilidad y mortalidad futura.

Caso probable de síndrome de reconstitución inmune por mpox en una persona con inmunosupresión avanzada por VIH / Probable case of mpox immune reconstitution inflammatory syndrome (IRIS) in a person with HIV disease

Se presenta el caso clínico de persona viviendo con VIH, con mala adherencia a tratamiento, sin vacunación previa para mpox, que evolucionó con un cuadro clínico probable de síndrome de reconstitución inmune posterior a reinicio de TAR, debido a la progresión de las lesiones cutáneas. Recibió tratamiento con tecovirimat por siete días, con evolución clínica favorable. Corresponde al primer caso reportado que recibió terapia con tecovirimat en Chile.

We report a clinical case of a person living with HIV with poor adherence to treatment, no previous mpox vaccination, who had a probable mpox syndrome immune reconstitution after restarting ART, due to worsening of skin lesions. He received treatment with tecovirimat for 7 days, clinically improved and was discharged in good condition. We reported this first clinical case that received tecovirimat in Chile.

Assessment of the level of awareness, knowledge, and risk perception of community members about mpox infection in Nigeria

Background: Since the resurgence of mpox disease in 2017, Nigeria alone has accounted for about 60% of confirmed cases reported in the African region. This study therefore aimed to understand the knowledge and perception of the general public towards the mpox infection. Methods: We conducted a cross-sectional study among 958 community members across three states (Oyo, Lagos and Jigawa) in Nigeria. Knowledge of mpox infection was assessed across four domains: (1) general knowledge, (2) transmission, (3) signs and symptoms, and (4) prevention and treatment where we assigned a score of 1 for each correct response. Binary logistic regression was conducted to explore factors associated with knowledge of mpox infection at 5% level of significance. We assessed perception of mpox infection across 5 constructs (perceived susceptibility, perceived severity, perceived benefits, perceived barriers, and self-efficacy) from the health belief model, using 3-point Likert scales. We used Kruskal-Wallis and Mann-Whitney- U tests to assess factors associated with each construct. Results: Overall, only about one-third (38.3%) of community members were aware of mpox infection. There were variations in perceptions and knowledge across the three states. Knowledge of mpox infection transmission, prevention, and treatment was low across the states. Only 28.9% of respondents knew that sharing utensils with an infected person is a means of contracting the disease, and just 15.9% were aware that mpox infection may resolve spontaneously. The mean of general knowledge scores was higher in Jigawa 14.8 (±3.2) compared to Lagos 12.1 (±4.1) and Oyo states 12.5 (±5.6) (p<0.001).Respondents with tertiary-level education (p=0.001) were significantly more likely to perceive themselves as susceptible to mpox while males (p<0.001) and respondents who live in Jigawa state (p=0.002) were significantly more likely to perceive mpox as severe with 90.5% believing that being infected will stop their daily activity (p<0.001). Perceived barriers to adherence to mpox preventive strategies were higher in Jigawa state (p<0.001), with 68.3% reporting that use of hand sanitizers might be expensive for them. Conclusion: The analysis of our findings revealed significant knowledge gaps and a very low level of public awareness about mpox. Key areas of limited knowledge included the disease's route of transmission, as well as its prevention and treatment. To control the spread of mpox infection, there is need to strengthen public health risk communication focusing on the transmission and preventive actions.

Knowledge and preventive practices related to Monkey pox among medical doctors in Sokoto metropolis of Sokoto State, Nigeria

Background: For effective control of Monkey pox (Mpox), clinicians need to have adequate knowledge of the disease and adopt appropriate practices to contain it. This study sought to assess the knowledge and practices of medical doctors regarding Monkey pox. Methodology: A descriptive cross-sectional design was utilized for the study and using a two stage sampling method, 210 medical doctors working in Sokoto metropolis were recruited into the study. A set of structured, pretested and self-administered questionnaire was used to obtain relevant information from the study participants. Data obtained was analyzed using SPSS computer software version 23 with level of statistical significance set at p<0.05 Results: All the respondents were aware of Mpox with more than half (52.3%) having the internet as their commonest source of information. The majority, ((72%) of the clinicians had good knowledge and only years of working experience was significantly associated with knowledge of the disease. Preventive practices were well exhibited by all the respondents with the majority (73%) having appropriate preventive practices. Conclusion and recommendation: This study has demonstrated good knowledge towards Mpox by clinicians in Sokoto metropolis, with a greater majority exhibiting appropriate preventive practices. Sustained awareness and retraining of health care workers in general is necessary to maintain the tempo of high index of suspicion for outbreaks of Mpox and other potential epidemics and also regular use of personal protective equipment

Level of knowledge, and risk perception of Mpox disease among Primary healthcare workers in Nigeria: a cross-sectional study of Jigawa, Oyo and Lagos States

Introduction: in Nigeria, studies on mpox among primary healthcare workers are scarce despite increasing incidence of mpox disease between 2017-2022. This study aimed to assess primary healthcare workers knowledge and perception of mpox in Nigeria. Methods: we conducted a cross-sectional survey among primary healthcare workers in Nigeria (Oyo, Lagos, and Jigawa) to represent different health system capacities and socio-economic contexts. Knowledge of mpox was evaluated in four domains: general knowledge, transmission, signs and symptoms, and prevention and treatment. Each correct response received a score of 1. We categorize the level of knowledge based on the score using the mean score as the cut-off by re-classifying the composite score of respondents for each state into a binary outcome of "good knowledge" if the mean composite score was greater or equals to the mean of overall knowledge score for the three states (16.1), and "poor knowledge" if the mean score equals to sixteen or less than sixteen (≤16). Factors associated with mpox knowledge were explored using multivariable logistic regression at a 5% significance level. Perception of mpox was assessed using five constructs from the health belief model, measured on 3-point Likert scales. Factors associated with each construct were analyzed using Kruskal-Wallis and Mann-Whitney-U tests. Results: in our study on healthcare workers, 78.3% (n=239) were aware of mpox disease. Their overall knowledge was moderate, particularly regarding transmission. Meanwhile, less than 50% knew mpox can be transmitted through sharing utensils, and 65.3% (n=156) understood contact with infected animals could lead to transmission. Lagos had lower overall knowledge scores (15.3±2.3) compared to Jigawa (16.9±2.3) and Oyo (16.3±2.5) (p<0.001). Perceived susceptibility was similar across states (p=0.127), and 97.5% (n=233) believed mpox can affect anyone, while 47.3% (113) felt they couldn't contract it. Jigawa exhibited higher perceived severity (p<0.001) and barriers to prevention (p<0.001). Conclusion: primary healthcare workers in all settings had limited knowledge of mpox transmission, with the perception of mpox varying by state and participants' socio-economic characteristics. The responsibility of HCW encompasses a range of activities that include diagnosis, patient care and education, and public health interventions amongst others. Hence it is important to educate HCWs on mpox disease to successfully curtail the spread of mpox.

Monkeypox infection and pregnancy in lower and middle-income countries: Precautions & recommendations

Abstract Monkeypox (MPX), an orthopoxviral disease endemic in Africa, is now a public health emergency of international concern (PHEIC) as declared by the World Health Organization in July 2023. Although it is generally mild, the overall case fatality rate was reported to be 3%, and the basic reproduction number (R0) is > 1 in men who have sex with men (MSM, i.e., Portugal (1.4), the United Kingdom (1.6), and Spain (1.8)). However, R0 is < 1 in other settings. In concordance with the smallpox virus, it is also expected to increase the risk of adverse outcomes for both the mother and the fetus. The outcomes of the disease in an immunocompromised state of pregnancy are scary, showing high mortality and morbidity of both mother and fetus, with up to a 75% risk of fetal side effects and a 25% risk of severe maternal diseases. Therefore, it warrants timely diagnosis and intervention. The reverse transcription polymerase chain reaction (RT PCR) test is the standard approach to diagnosis. We summarized the recent findings of MPX on pregnancy, and the associated risk factors. We also give recommendations for active fetal surveillance, perinatal care, and good reporting to improve outcomes. The available vaccines have shown promise for primary disease prevention.

La viruela sísmica aspectos relacionados a la fisiopatología, genoma, patogénesis, transmisión, replicación e inmunología / Aspects Related to pathophysiology, Genome, Pathogenesis, Transmission, Replication and Immunology of Monkeypox

Introducción: La viruela símica es una enfermedad zoonótica identificada por primera vez en 1958. El virus es un miembro del género Orthopoxvirus, de la familia Poxviridae. Infecta a una amplia variedad de mamíferos y se desconoce su reservorio natural. Objetivos: Describir los aspectos importantes relacionados a la fisiopatología, genoma, patogénesis, transmisión, replicación e inmunología de la viruela símica. Métodos: Se realizó una búsqueda de artículos originales, reportes de casos, revisiones bibliográficas y sistemáticas en el Portal Regional de la BVS, PubMed, Science, Nature y Lancet. Se consultaron los informes de la Organización Mundial de la Salud y la Organización Panamericana de la Salud sobre la viruela símica. Resultados: La propagación del virus de la viruela símica puede ocurrir a través del contacto cercano con lesiones, fluidos corporales, gotitas respiratorias y objetos contaminados. Una vez dentro del organismo, el virus infecta mucosas, células epiteliales y células inmunitarias de los tejidos adyacentes. El virus se replica y disemina rápidamente a través del sistema hemático y linfático. Las células T desempeñan un papel importante en la regulación de la respuesta inmunitaria contra el virus. Sin embargo, los Orthopoxvirus han desarrollado varios mecanismos para la evasión de la respuesta inmunitaria. Conclusiones: Los aspectos importantes descritos que se tuvieron en cuenta acerca de la transmisión de la viruela símica han tenido cambio significativo con el tiempo. El brote mundial de viruela símica de 2022 presentó una cadena de transmisión principalmente entre humanos asociada al contacto sexual(AU).

Introduction: Monkeypox is a zoonotic disease that was first identified in 1958. The virus is a member of Orthopoxvirus genus, of Poxviridae family. It infects wide variety of mammals and its natural reservoir is unknown. Objectives: To describe the important aspects related to pathophysiology, genome, pathogenesis, transmission, replication and immunology of monkeypox. Methods: A search of original articles, case reports, bibliographic and systematic reviews was carried out in VHL Regional Portal, PubMed, Science, Nature and Lancet. Reports from the World Health Organization and the Pan American Health Organization on monkeypox were consulted. Results: Spread of monkeypox virus can occur through close contact with lesions, body fluids, respiratory droplets, and contaminated objects. Once inside the body, the virus infects mucous membranes, epithelial cells and immune cells of adjacent tissues. The virus replicates and spreads rapidly through the blood and lymphatic system. T cells play an important role in regulating the immune response against the virus. However, Orthopoxviruses have developed several mechanisms to evade the immune response. Conclusions: The important aspects described, taken into account about monkeypox transmission, have significantly changed over time. 2022 global monkeypox outbreak presented a chain of transmission primarily among humans associated with sexual contact(AU)

Asociación entre las tendencias de búsqueda en internet con el número de casos confirmados por la viruela símica: estudio multinacional en diez países / Association between internet search trends and the number of confirmed monkeypox cases: a multinational study in ten countries

INTRODUCCIÓN: La viruela símica es una infección zoonótica que se ha distribuido por todo el mundo. La búsqueda de información en internet refleja el interés y concientización de la población acerca de salud. OBJETIVO: Determinar la asociación entre el volumen relativo de búsquedas en internet con el número de casos confirmados por la viruela símica en diez países. MÉTODOS: Se realizó un estudio obser- vacional, analítico, retrospectivo, utilizando la herramienta Google Trends (GT™) para encontrar el volumen relativo búsqueda (VRB) sobre viruela símica desde 01 de enero al 31 de agosto del 2022 usando términos de búsqueda en el idioma oficial de los 10 países con mayor número de casos en dichas fechas, registrado por Our World in Data. Para establecer la relación lineal entre el VRB con los nuevos de casos por día se usó el coeficiente de correlación de Pearson con un nivel de significancia (p ≤ 0,05). RESULTADOS: Se encontró un coeficiente de correlación de Pearson fuerte en Brasil (Rp = 0,562,p = 0,001), y débil en países como Alemania (Rp = 0,281, p = 0,004), Estados Unidos de Norteamérica (Rp = 0,255, p = 0,008), España (Rp = 0,122, p = 0,213), Perú (Rp = 0,120, p = 0,333), Canadá (Rp = 0,116, p = 0,238), Francia (Rp = 0,095, p = 0,335), Reino Unido (Rp = 0,085, p = 0,362), Portugal (Rp = 0,024, p = 0,805) y Países Bajos (Rp = 0,067, p = 0,497). CONCLUSIÓN: Nuestro estudio evidencio que el VRB presento una relación positiva con el número de nuevos casos de viruela símica. Asimismo, se observo un coeficiente de correlación fuerte en Brasil, y en el resto de países fue débil.

BACKGROUND: Smallpox is a zoonotic infection that has been distributed worldwide. The search for information on the Internet reflects the interest and awareness of the population about health. AIM: To determine the correlation between the relative volume of internet searches and the number of confirmed cases of smallpox in ten countries. METHODS: An observational, analytical, retrospective study was conducted using the Google Trends (GT™) tool to find the relative search volume (RSV) on monkeypox from January 1 to August 31, 2022 using search terms in the official language of the 10 countries with the highest number of cases on those dates, as recorded by Our World in Data. To establish the relationship between RSV and new cases per day, Spearman's correlation was used with a significance level (p ≤ 0.05). RESULTS: A. strong Pearson correlation coefficient was found in Brazil (Rp = 0.562, p = 0.001), and weak in countries like Germany (Rp = 0.281, p = 0.004), United States (Rp = 0.255, p = 0.008), Spain (Rp = 0. 122, p = 0.213), Peru (Rp = 0.120, p = 0.333), Canada (Rp = 0.116, p = 0.238), France (Rp = 0.095, p = 0.335), United Kingdom (Rp = 0.085, p = 0.362), Portugal (Rp = 0.024, p = 0.805) and Netherlands (Rp = 0.067, p = 0.497). CONCLUSION: Our study showed that RSV had a positive relationship with the number of new cases of smallpox. Also, a strong correlation coefficient was observed in Brazil, while the rest of the countries showed a weak correlation coefficient.

Primer caso de transmisión de mpox mediante toma de muestra por desteche en Chile / First case report of mpox transmission through unroofing sample collection in Chile

Mpox es una zoonosis vírica que causa síntomas similares a la viruela, aunque menos graves. La infección fue descrita inicialmente en África central y occidental. Luego del brote multinacional ocurrido el año 2022, ya no es considerada una emergencia de salud pública de importancia internacional. El mecanismo de transmisión es por contacto físico estrecho o directo con lesiones cutáneas de individuos infectados. Presentamos el caso clínico de una enfermera que se infectó por mpox tras un accidente cortopunzante durante la toma de muestra de una lesión por desteche con bisturí en un paciente con VIH. La transmisión percutánea tuvo un período de incubación corto, seguido de una lesión cutánea y síntomas sistémicos. Aunque infrecuente, se destaca el riesgo de transmisión ocupacional de mpox en la atención clínica. Es importante que el personal sanitario adhiera estrictamente a las medidas de prevención, como el uso de equipo de protección personal y la práctica segura en la toma de muestra.

Monkeypox is a viral zoonosis that causes symptoms similar to smallpox, but less severe. The infection was initially described primarily in central and western Africa. After multi-country outbreak in 2022; it is currently no longer a public health emergency of international concern. The main mode of transmission is through close or direct contact with the skin lesions of an infected individual. We report a case of a nurse was infected with mpox after a needlestick injury during a skin sample collection from an HIV-positive patient. Percutaneous transmission resulted in a short incubation period, followed by a skin lesion and systemic symptoms. This case highlights the risk of occupational transmission of mpox in healthcare settings. It is important for healthcare workers to take rigorous prevention measures, such as the use of appropriate personal protective equipment and safe sample collection practices.

La viruela símica como enfermedad zoonótica viral y reemergente en el actual contexto sanitario mundial / Mpox as a Viral Zoonotic Disease Reemerging in the Current Global Health Context

Introducción: La viruela símica es una enfermedad zoonótica que también se trasmite de persona a persona por contacto estrecho. En el brote actual hasta el 31 de agosto de 2022 se reportaban 50 496 casos diagnosticados en 101 países, por lo que se consideró una situación preocupante por la Organización Mundial de la Salud. Objetivo: Exponer información actualizada sobre la viruela símica en el contexto sanitario actual. Métodos: Se realizó una búsqueda de literatura científica en las bases de datos ScienceDirect, PubMed/Medline, SciELO y Google Académico, mediante los descriptores o palabras relacionadas con la enfermedad, para encontrar revisiones, comunicados, informes, distintos artículos de revistas, entre otros documentos especializados de producción científica. Se seleccionó un total de 30 citas, actualizadas en su totalidad. Desarrollo: Desde su identificación en humanos se han reportado brotes de viruela símica en varios países; el más preocupante, ha sido el de reciente declaración en 2022, debido a la presencia de casos en países no endémicos, con un alcance geográfico extenso. Las manifestaciones clínicas pueden cursar con síntomas leves, como erupciones en la cara y el resto del cuerpo, fiebre, cefalea, mialgias y fatiga, por lo que no constituye una enfermedad potencialmente mortal; sin embargo, de presentarse comorbilidades la evolución podría ser tórpida. Conclusiones: La presencia de casos de viruela símica en humanos se ha mantenido desde su aparición, sin encontrar un tratamiento específico y vacunas autorizadas para su administración, lo que podría generar un aumento de contagios y fallecidos(AU)

Introduction: Mpox is a zoonotic disease also transmitted from person to person by close contact. The current outbreak, up to August 31, 2022, reported 50 496 diagnosed cases from 101 countries; therefore; it was considered a situation of concern by the World Health Organization. Objective: To present updated information on Mpox in the current health context. Methods: A scientific literature search was carried out in the databases ScienceDirect, PubMed/Medline, SciELO and Google Scholar, using descriptors or words related to the disease, in order to find reviews, communications, reports, different journal articles, among other specialized documents of scientific production. A total of 30 entirely updated citations were selected. Development: Since Mpox was identified in humans, outbreaks of the disease have been reported in several countries; the most worrisome has been reported recently in 2022, due to the presence of cases in nonendemic countries, with an extensive geographical scope. The clinical manifestations may occur with mild symptoms, such as rash on the face or the rest of the body, fever, headache, myalgia and fatigue; therefore, it is not a potentially mortal disease. However, in case of comorbidity, the evolution could be torpid. Conclusions: Mpox cases in humans has been present since its appearance, without any specific treatment or vaccines authorized to be administered, which could generate an increase in contagions and deaths(AU)
