Emergence of monkeypox virus in central Argentina: Epidemiological features and first complete genome sequences in the country.

Monkeypox (Mpox) is a zoonotic disease caused by the monkeypox virus (MPXV). MPXV can be transmitted by close contact with lesions, body fluids, respiratory droplets, and contaminated materials. A new pattern of spread among sexual networks has been recently described. The present work aimed to report the epidemiological and genomic characterization of the 2022 MPXV outbreak in central Argentina. A total of 113 scabs and/or lesion swab specimens were studied. MPXV infection was confirmed in 46.0% of the studied patients, all of whom were men. Varicella-zoster virus infection was the most frequent differential diagnosis. Eight complete viral genomes were obtained by next-generation sequencing. The Argentinian sequences were grouped intermingled with other sequences from the 2022 MPXV outbreak, related to samples from the USA, Europe, and Peru. Taken together, our study provided an initial assessment of the genetic and epidemiological characteristics of the 2022 MPXV outbreak in Córdoba, Argentina.

Mpox - Formerly Monkey Pox - in Dermatology: A Review of Epidemiologic Features, Clinical Presentation, Diagnosis, and Treatment. / MPOX (antes viruela del mono): revisión de los aspectos clínicos, epidemiológicos, diagnósticos y terapéuticos más relevantes para el dermatólogo.

Mpox is an emerging zoonotic disease that has spread rapidly around the world. It has been declared a public health emergency of international concern by the World Health Organization. This review is an update for dermatologists on the epidemiology, clinical presentation, diagnosis, and treatment of Mpox. The primary mode of transmission in the current outbreak is close physical contact during sexual activity. Although most of the initial cases were reported in men who have sex with men, anyone who has close contact with an infected person or contaminated fomites is at risk. Classic prodromal features of Mpox include subclinical manifestations and a mild rash. Complications are common but rarely require hospitalization. Polymerase chain reaction analysis of mucocutaneous lesions is the test of choice for a definitive diagnosis. In the absence of specific treatments, management focuses on symptomatic relief.

Perichondritis and auricular cellulitis related to piercings as first manifestation of monkeypox.

INTRODUCTION: Pinna infections are usually due to Staphylococcus aureus infection. It is common for the patient to have had an earring in the area of infection. Monkeypox infection has gone from being an endemic infection to a worldwide health emergency. CASE SUMMARY: In this article we present five cases of monkeypox earring infection of the pinna and what common features we have seen that differentiate them from Staphylococcus aureus infection. DISCUSSION: Symptoms of monkeypox include general malaise, fever with uni- or bilateral lymphadenopathy, and then the appearance within one or two days of skin lesions, we want to alert he otolaryngologist and the medical society to the possibility the diagnostic possibility of monkeypox in patients with an auricular perichondritis.

[Vaccines against monkeypox]. / Vacunas frente a la viruela del mono (monkeypox).

The monkeypox virus is a virus that has 90% genomic homology with the human (smallpox), but it is naturally transmitted between different wild animal reservoirs and is considered a zoonosis. Throughout the 20th century, different vaccines based on the vaccinia poxvirus were developed and used for vaccination against smallpox. After the eradication of smallpox, these vaccines were no longer used. Current vaccines against monkeypox virus are classified by the WHO as replicative (ACAM2000), minimally replicative (LC16m8) and non-replicative (MVA-BN), the latter being the one currently used. The 2022 extra-African monkeypox virus epidemic has highlighted the lack of vaccines with proven efficacy and low reactogenicity. It is considered that the use of this vaccine in the current outbreak may play a role in the prevention or attenuation of the disease as pre-exposure prophylaxis in close contacts of confirmed cases.

Mpox and pregnancy: A neglected disease and its impact on perinatal health.

Viral infections during pregnancy have been one of the leading causes associated with significant perinatal problems, such as congenital defects, fetal neurological syndromes, stillbirths, and adverse pregnancy outcomes. The mpox virus infection, caused by an Orthopoxvirus related to the human smallpox virus, was declared a global health emergency by the World Health Organization in July 2022 due to the large number of cases emerging outside the usual endemic area in Africa. There is little information on the impact of mpox virus infection during pregnancy, although the limited evidence available shows a high rate of fetal harm. This review addresses the problem of mpox virus infection in pregnant women and provides indications for its prevention, diagnosis, and treatment.

[Monkeypox with eccrine duct involvement]. / Viruela del mono con afectación de conductos ecrinos.

Monkeypox was historically considered a zoonotic disease restricted to areas with an animal reservoir and with limited possibilities of human transmission. However, the recent increase in incidence in non-endemic areas, together with the demonstration of human transmission, has led to more attention being paid to this disease. We present the case of a 27-year-old man with cutaneous lesions and perianal ulcers, clinically suggestive of a viral disease. Monkeypox was demonstrated with PCR analysis. The histological features and differential diagnoses of monkeypox are discussed and the characteristic histopathological pattern of eccrine gland epithelium is described which, if found in an ulcerated lesion, should raise suspicion of monkeypox.

Otorhinolaryngological manifestations in monkeypox.

BACKGROUND AND OBJECTIVE: In the current health emergency declared by the World Health Organization (WHO) for monkeypox, few data on the otorhinolaryngological (ENT) manifestations of the disease have been detailed. The purpose of this study is to describe the clinical features of the ENT manifestations in monkeypox. MATERIALS AND METHODS: Descriptive analysis of 11 consecutive patients with odynodysphagia or oral cavity lesions referred to the ENT emergency department of a tertiary hospital with epidemiological risk factors suggestive of monkeypox infection. Clinical, diagnostic and treatment findings are described. RESULTS: 90.9% of the patients had previous unsafe sexual contact. The predominant presenting features included fever over 38 °C with severe odynodysphagia. Physical examination showed ulcers and exudative lesions of variable presentation in the upper respiratory tract. Smear of the lesions confirmed polymerase chain reaction (PCR) positivity for monkeypox in all patients. CONCLUSIONS: Monkeypox virus infection can occur in the ENT area with multiple manifestations that require a high degree of epidemiological suspicion and confirmation with PCR to reach a diagnosis of certainty.

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.

MPOX, o que sabemos sobre propagação e controle: uma revisão integrativa / MPOX, what we know about propagation and control: an integrative review / Viruela del mono, qué sabemos sobre la propagación y el control: una revisión integradora

Esta é uma revisão integrativa que busca compreender os fatores associados à propagação e controle de mpox, seguindo as recomendações estabelecidas pela declaração Preferred Reporting Items for Systematic Reviews and Meta-Analyses. A consulta foi feita nas bases de dados PubMed, Lilacs e Cochrane Library. Foram selecionados quinze artigos, com amostra majoritária de homens que fazem sexo sem proteção com homens e homens que viajaram para locais com surto da doença ou tiveram contato com pessoas infectadas. Os principais fatores associados à infecção e à propagação da doença foram históricos de viagem, sexo desprotegido, ingestão de carne possivelmente contaminada, aglomerados e contato próximo com pessoa sintomática. Quanto aos fatores relacionados à prevenção, estão principalmente associados à triagem de casos suspeitos, hábitos de higiene pessoal, uso de equipamentos de proteção individual e isolamento do doente.

This integrative review examines the factors associated with mpox spread and control, following the recommendations established by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Bibliographic search was conducted on the PubMed, Lilacs and Cochrane Library databases. The final sample included 15 articles, mostly composed of men who have unprotected sex with men and men who traveled to places with a mpox outbreak or had contact with infected people. Travel history, unprotected sex, eating potentially contaminated meat, crowding and close contact with a symptomatic person were the main factors associated with mpox infection and spread. Prevention is mainly associated with the screening of suspected cases, personal hygiene habits, use of personal protective equipment and patient isolation.

Atypical perianal and buttocks epidermal-dermal necrosis in Human Monkeypox. Histopathological study of the lesion in Peru

We report the histopathological study of a large, black, crusted lesion with symmetrical distribution in both buttocks and perineum, never described, in a man who has sex with men (MSM) and proctitis associated with Human Monkey Pox Virus (hMPXV) and HIV-AIDS infection never treated. A 39-year-old male, homosexual, HIV-AIDS without Highly Active Antiretroviral Therapy (HAART), was admitted to a hospital in Lima, Peru, with papulopustular lesions on the body and perianal area. Days later, a large, crusty, black lesion with a symmetrical distribution appeared on the buttocks and perineum. The tissue culture was negative. Wedge biopsy of the lesion showed typical MPXV cytopathogenics lesions in addition to fibrin micro thrombosis in the underlying papillary dermis. The histopathological findings of the scabby and black lesion are the classic ones described by Stagles, except for the phenomenon of fibrin micro thrombosis in the papillary dermis, a novel cytopathogenic effect of MPXV with clinical relevance (epidermal-dermal necrosis).

Reportamos el estudio histopatológico de una gran lesión costrosa, negra, de distribución simétrica en ambas nalgas y periné, nunca descrito, en un hombre que tiene sexo con hombres (HSH) y proctitis asociado a Viruela del Mono Humana (hMPXV) e infección por VIH-SIDA nunca tratado. Un varón de 39 años, homosexual, VIH-SIDA sin Terapia Antirretroviral de Gran Actividad (TARGA), ingresó en un hospital de Lima, Perú, con lesiones papulopustulosas en el cuerpo y el area perianal. Días después apareció una gran lesión negra, costrosa de distribución simétrica en las nalgas y periné. El cultivo de tejidos fue negativo. La biopsia en cuña de la lesión mostró lesiones citopatogénicas típicas de MPXV, además de microtrombosis de fibrina en la dermis papilar subyacente. Los hallazgos histopatológicos de la lesión costrosa y negra que reportamos son los clásicos descritos por Stagles, a excepción del fenómeno de microtrombosis de fibrina en la dermis papilar, un efecto citopatogénico novedoso de MPXV con relevancia clínica (necrosis epidermo-dérmico).

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)

Viruela símica: una revisión narrativa de la fisiopatología / Monkeypox: a narrative review of pathophysiology

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, pero se desconoce su reservorio natural. El virus del brote de 2022 pertenece a los clados IIa y IIb. Es probable que la aparición del brote actual se deba a las importaciones del brote de Nigeria de 2017-2018. La propagación de persona a persona puede ocurrir a través del contacto cercano con lesiones, fluidos corporales, gotitas respiratorias y objetos contaminados. Una vez dentro del organismo, el virus infecta las mucosas, células epiteliales y células inmunitarias de los tejidos adyacentes. Luego, 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. La vigilancia de la enfermedad es un factor crucial en la evaluación de riesgo del virus y del control del brote. Para esta revisión se realizó la búsqueda de los principales artículos relacionados a la patogenia del virus, publicados hasta la fecha. El artículo destaca la necesidad de nuevos estudios sobre transmisibilidad y patogenicidad de las cepas asociadas al brote de 2022.

Monkeypox is a zoonotic disease first identified in 1958. The virus is a member of the genus Orthopoxvirus, family Poxviridae. It infects a wide variety of mammals, but its natural reservoir is unknown. The virus in the 2022 outbreak belongs to clades IIa and IIb. The emergence of the current outbreak is likely to be due to importations from the 2017-2018 Nigerian outbreak. Person to person spread 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 in adjacent tissues. The virus then replicates and spreads rapidly through the blood and lymphatic system. Tcells play an important role in regulating the immune response against the virus. However, Orthopoxvirus have evolved several mechanisms for evasion of the immune response. Disease surveillance is a crucial factor in virus risk assessment and outbreak control. For this review we searched for the main articles related to the pathogenesis of the virus published to date. The article highlights the need for further studies on transmissibility and pathogenicity of the strains associated with the 2022 outbreak.

Características clínicas y epidemiológicas de la viruela del mono en una serie de casos tratados en un establecimiento de salud del Perú

La infección por el virus de la viruela del mono es una zoonosis producida por un virus tipo DNA, del género orthopoxvirus. En este reporte se describe una serie de 12 casos cuya media de edad fue 36 años, con antecedente de sexo entre hombres en el 66%; previo al inicio de los síntomas el 50% manifestó haber tenido relaciones sexuales con desconocido. Los síntomas prodrómicos se presentaron en el 90%, entre 1 y 4 días caracterizados por fiebre, cefalea, mialgia. Las lesiones dérmicas fueron pústulas-vesículas, pápulas, costras localizadas principalmente en extremidades, cara-tórax y genitales. Todos los casos tuvieron una evolución favorable.

Monkeypox virus infection is a zoonosis caused by a DNA-like virus of the orthopoxvirus. This report describes a series of 12 cases whose mean age was 36 years, with a history of sex among men in 66%; prior to the onset of symptoms, 50% said they had had sex with a stranger. Prodromal symptoms occurred in 90%, between 1 and 4 days characterized by fever, headache, mialgia. The dermal lesions were pustules-vesicles, papules, scabs located mainly on extremities, face-thorax and genitals. All cases had a favorable evolution.

Proctitis y úlcera ano-rectal como presentación inicial en pacientes con Viruela símica

Objetivo: Describir hallazgos clínicos, quirúrgicos e imagenológicos de la patología anorrectal en pacientes con Viruela Símica. Materiales y Métodos: Reporte de serie de casos clínicos, observacional, en pacientes con Viruela Símica tratados en un centro de salud privado desde agosto 2022 a diciembre 2022. Resultados: El 100% de los casos pertenecía al sexo masculino, la edad promedio fue de 32 años, todos los pacientes mantuvieron relaciones sexuales con otros hombres, la mayoría debuto con síntomas rectales, incluyendo proctalgia, prurito anal y heces diarreicas con mucosidad. El diagnóstico se confirmó mediante PCR (reacción de polimerasa en cadena) y el tratamiento fue sintomático, con mejoría en todos los pacientes en un seguimiento de 10 días. Discusión: La Viruela Símica es una enfermedad viral que se encuentra, principalmente, en regiones remotas de África Central, con brotes esporádicos en países africanos. Está relacionada con el virus de la viruela y se transmite, principalmente, del contacto con animales infectados o fluidos corporales. La enfermedad presenta síntomas similares a la gripe, seguidos del desarrollo de una erupción cutánea que progresa a pústulas y costras. No hay tratamiento específico para la viruela símica, el manejo medico alivia los síntomas. El brote de viruela símica en 2022 presentó características novedosas y atípicas en su forma de presentación. Conclusión: Los síntomas rectales asociados a una historia clínica compatible con viruela símica se deben considerar como diagnóstico diferencial a la proctitis por esta etiología específica y emergente.

Objective: To describe clinical, surgical and imaging findings of anorectal pathology in patients with monkeypox. Materials and Methods: Observational clinical case series report in patients with monkeypox treated in a private health center from August 2022 to December 2022. Results: 100% of the cases were male, the average age was 32 years old, all patients had sexual intercourse with other men, most debuted with rectal symptoms, including proctalgia, anal itching, and diarrheal stools with mucus. Diagnosis was confirmed by PCR (polymerase chain reaction) and treatment was symptomatic, with improvement in all patients at a 10-day follow-up. Discussion: Monkeypox is a viral disease found mainly in remote regions of Central Africa, with sporadic outbreaks in African countries. It is related to the smallpox virus and is transmitted primarily from contact with infected animals or bodily fluids. The disease presents with flu-like symptoms, followed by the development of a skin rash that progresses to pustules and scabs. There is no specific treatment for monkeypox; medical management alleviates the symptoms. The monkeypox outbreak in 2022 presented novel and atypical characteristics in its presentation. Conclusion: Rectal symptoms associated with a clinical history compatible with monkeypox should be considered as a differential diagnosis of proctitis due to this specific and emerging etiology.

As recomendações em saúde pública como microagressões: varíola dos macacos e populações LGBTQIA+ / Public health recommendations as microaggressions: monkeypox and LGBTQIA+ populations / Las recomendaciones de salud pública como microagresiones: viruela del mono y poblaciones LGBTQIA+

Resumo: O artigo tem por objetivo analisar recomendações de saúde pública da Organização Mundial da Saúde e das manifestações de seu Diretor-geral durante a epidemia de varíola dos macacos endereçadas a homens que fazem sexo com homens (HSH) à luz da microagressão como categoria de análise. Questiona-se o potencial estigmatizador de divulgação estatística, para público amplo, de que 98% dos infectados estavam entre HSH, bem como a utilização da própria categoria HSH e da sugestão de abstinência sexual parcial ou total como forma de interromper a disseminação viral. Sugere-se como alternativas capazes de, simultaneamente, garantir políticas de prevenção de doenças sem estigmatizar grupos vulneráveis, especialmente a população LGBTQIA+: (i) diferenciar as divulgações voltadas ao público geral das destinadas às populações predominantemente contaminadas e sujeitas a maior grau de vulnerabilidade social; (ii) superar a utilização da expressão HSH para, nas comunicações destinadas à ampla audiência, utilizar a expressão SGD (população sexo e gênero diversa), mantendo-se o procedimento de registrar, nas pesquisas científicas e nos formulários de atendimento, a identidade de gênero e a orientação sexual por autodeclaração dos pacientes; (iii) evitar mensagens que abordem a sexualidade de modo negativo, reforcem uma vivência sexual majoritária e gerem uma responsabilização socialmente punitiva do infectado, excluindo, pois, das recomendações voltadas ao público amplo a sugestão de abstinência sexual parcial, relativa à redução do número de parceiros, ou de abstinência sexual total, exceto para os casos de pessoas na fase ativa da infecção ou no período imediato à recuperação.

Abstract: The article aims to analyze public health recommendations of the World Health Organization and the manifestations of its Director-General during the mpox epidemic addressed to men who have sex with men (MSM) in the light of microaggression as a category of analysis. The stigmatizing potential of statistical disclosure to a broad public that 98% of those infected were among MSM is questioned, as well as the use of the MSM category itself and the suggestion of partial or total sexual abstinence as a way to stop viral dissemination. The following are suggested as alternatives capable of simultaneously guaranteeing disease prevention policies without stigmatizing vulnerable groups, especially the LGBTQIA+ population: (i) differentiating the disclosures addressed to the general public from those aimed at populations predominantly contaminated and subject to a higher degree of social vulnerability; (ii) overcoming the use of the expression MSM, in communications aimed at a wide audience, to use the expression SGD (sex and gender diverse population), maintaining the procedure of recording, in scientific research and in medical forms, the gender identity and sexual orientation by self-declaration of patients; (iii) avoiding messages that negatively address sexuality, reinforce a majority sexual experience, and generate a socially punitive responsibility of the infected, thus excluding from the recommendations aimed at the broad public, the suggestion of partial sexual abstinence, related to the reduction of the number of partners, or total sexual abstinence, except for the cases of people in the active phase of infection or in the immediate period of recovery.

Resumen: Este artículo tiene como objetivo analizar las recomendaciones de salud pública de la Organización Mundial de la Salud y las manifestaciones de su Director General durante la epidemia de viruela del mono, dirigidas a los hombres que tienen relaciones sexuales con hombres (HSH), a la luz de la microagresión como categoría de análisis. Se discute el potencial estigma de la divulgación estadística para una amplia audiencia por haber informado que el 98% de los infectados estaban entre HSH, así como el uso de la categoría HSH en sí y la sugerencia de abstinencia sexual parcial o total como forma de detener la propagación viral. Se sugieren como alternativas capaces de garantizar simultáneamente políticas de prevención de enfermedades sin estigmatizar a los grupos vulnerables, especialmente la población LGBTQIA+: (i) distinguir las divulgaciones dirigidas al público en general de las destinadas a poblaciones predominantemente contaminadas y sujetas a un mayor grado de vulnerabilidad social; (ii) dejar de usar el término HSH para, en comunicaciones dirigidas a la amplia audiencia, emplear el SGD (población sexo y género diversa), manteniendo el procedimiento de registro (en investigaciones científicas y formularios de atención) de la identidad de género y la orientación sexual por autodeclaración de los pacientes; (iii) evitar mensajes que tratan la sexualidad de manera negativa, que aseguran una experiencia sexual mayoritaria y que generan una rendición de cuentas socialmente punitiva de los infectados, excluyendo, por lo tanto, de las recomendaciones dirigidas al público en general la sugerencia de abstinencia sexual parcial, relativa a la reducción del número de parejas, o de abstinencia total, excepto en los casos de estadio activo de la infección o del período inmediato de recuperación.

Recomendación del Comité Asesor de Vacunas y Estrategias de Inmunización (CAVEI) sobre vacunación contra viruela símica en Chile / Recommendation of the Advisory Committee on Vaccines and Immunization Strategies on monkeypox vaccination in Chile

La viruela del mono fue declarada emergencia de salud pública de importancia internacional por la Organización Mundial de la Salud el año 2022. En Chile, hasta septiembre se han confirmado sobre 450 enfermos, mayoritariamente hombres jóvenes. Este poxvirus zoonótico se transmite entre humanos por contacto estrecho; la enfermedad es autolimitada y puede ser fatal en inmunocomprometidos. La prevención mediante inmunización es importante. MVA-BN es una de las tres vacunas disponibles, de 3° generación, contiene el virus vaccinia atenuado, no replicante por lo que se puede administrar a pacientes inmunocomprometidos y mujeres embarazadas y está aprobada para viruela símica en personas > 18 años. La información disponible sobre eficacia y efectividad es limitada. El CAVEI recomienda incorporar esta vacuna para interrumpir la cadena de transmisión y reducir el riesgo de enfermedad grave, en dos dosis separadas por 28 días, por vía subcutánea, priorizando el uso post-exposición para contactos estrechos con riesgo de enfermedad grave, idealmente en los primeros 4 días y hasta 14 días post contacto de riesgo y en ausencia de síntomas. Cuando el suministro de vacunas lo permita, se recomienda prevención pre-exposición para personas con alto riesgo ocupacional o por prácticas sexuales. Esta recomendación podría modificarse según la epidemiología, el suministro de vacunas y nueva información científica.

Monkeypox was declared a public health emergency of international concern by the World Health Organization during 2022. In Chile, over 450 patients have been confirmed until September, mostly young men. This zoonotic poxvirus is transmitted from humans to humans through close contact; it is a self-limiting disease and can be fatal in people with immunodeficiency. Prevention by immunization is important. MVA-BN, one of the three vaccines available, it is a third generation vaccine, based on non-replicating modified vaccinia virus, therefore can be administered to immunocompromised patients and pregnant women and it has been approved for monkeypox in people over 18 years of age. The available information on efficacy and effectiveness is limited. The CAVEI recommends incorporating this vaccine to interrupt the chain of transmission and reduce the risk of severe disease, administered subcutaneously in two doses, 28 days apart, prioritizing post exposure use for close contacts of confirmed cases with risk of severe disease, ideally within 4 days of exposure and it can be used up to 14 days after exposure and in the absence of symptoms. When the vaccine supply allows it, its application is recommended as pre-exposure prevention for people with high-risk sexual practices or with occupational risk. This recommendation could be modified according to epidemiology, vaccines supply and new scientific information.
