Lineamientos técnicos para la detección y control de casos de viruela símica / Technical guidelines for the detection and control of monkeypox cases

La Viruela Símica es una zoonosis viral (transmitida de animales a humanos) con síntomas parecidos a la viruela, aunque de menor gravedad. Fue aislada por primera vez en 1958 en brote de enfermedad parecida a viruela en colonias de monos en Dinamarca. El primer caso en humano se reportó en 1970, en la República Democrática del Congo. Con la erradicación de la viruela en 1980 y el posterior cese de la vacunación contra la misma, la viruela del simio se ha convertido en el ortopoxvirus más importante para la salud pública a nivel mundial. Desde 1970 a 2022, han sido 15 países los que han reportado casos, 11 de los cuales son africanos (Benín, Camerún, República Centroafricana, República Democrática del Congo, Gabón, Costa de Marfil, Liberia, Nigeria, República del Congo, Sierra Leona y Sudán del Sur) donde la enfermedad es endémica Por lo que los presentes Lineamientos técnicos establecen la detección oportuna y control de casos sospechosos o confirmados de viruela símica y serán revisados y actualizados cuando existan cambios o avances en los tratamientos y abordajes, o en la estructura orgánica o funcionamiento del MINSAL

Monkeypox is a viral zoonosis (transmitted from animals to humans) with symptoms similar to smallpox, although less severe. It was first isolated in 1958 in an outbreak of smallpox-like disease in monkey colonies in Denmark. The first human case was reported in 1970, in the Democratic Republic of the Congo. With the eradication of smallpox in 1980 and the subsequent cessation of vaccination against it, monkeypox has become the most important orthopoxvirus for public health worldwide. From 1970 to 2022, 15 countries have reported cases, 11 of which are African (Benin, Cameroon, Central African Republic, Democratic Republic of Congo, Gabon, Ivory Coast, Liberia, Nigeria, Republic of Congo, Sierra Leone and South Sudan) where the disease is endemic. Therefore, these technical guidelines establish the timely detection and control of suspected or confirmed cases of monkeypox and will be reviewed and updated when there are changes or advances in treatments and approaches, or in the organizational structure or operation of MINSAL.

Viruela símica: revisión bibliográfica / Monkeypox: Bibliographic Review

La viruela símica es una enfermedad que ocurre en los monos, sin embargo también se han presentado casos en humanos desde 1970, transformándose en una zoonosis de origen viral, la sintomatología es similar a la viruela pero menos grave. Objetivo: Proporcionar información actualizada sobre la viruela símica, situación epidemiológica, sintomatología, letalidad, diagnóstico, tratamiento y medidas de prevención Materiales y métodos: Se realizó una búsqueda de literatura científica en las bases de datos Organización Mundial de la Salud, Google Académico y PubMed, se eligieron los descriptores o palabras relacionadas con la enfermedad y se realizó la búsqueda para la descripción de reportes de casos y brotes producidas por la viruela símica. Resultados: Desde que se reportó el primer caso en humanos, han existido brotes en el continente africano, fuera de éste, se han reportados varios casos y brotes en otros países, la mayoría en los Estados Unidos. El último evento se reporta en mayo de 2022 y es de preocupación mundial, debido a la aparición en varios países no endémicos. Conclusiones: La presencia de casos de viruela símica en humanos se ha mantenido desde su aparición, la ausencia de un tratamiento específico y vacunas autorizadas para su administración, podrían generar un aumento en la morbimortalidad(AU)

Monkeypox is a disease that occurs in monkeys, however there have also been cases in humans since 1970, becoming a zoonosis of viral origin, the symptoms are similar to smallpox but less severe. Objective: To provide updated information on monkeypox, epidemiological situation, symptomatology, lethality, diagnosis, treatment and prevention measures. Materials and methods: A search of scientific literature was carried out in the World Health Organization, Google Scholar and PubMed databases. , the descriptors or words related to the disease were chosen and the search was performed for the description of case reports and outbreaks caused by monkeypox. Results: Since the first human case was reported, there have been outbreaks on the African continent, outside of Africa, several cases and outbreaks have been reported in other countries, most in the United States. The last event is reported in May 2022 and is of global concern, due to the appearance in several non-endemic countries. Conclusions: The presence of cases of monkeypox in humans has been maintained since its appearance, the absence of a specific treatment and vaccines authorized for its administration, could generate an increase in morbidity and mortality(AU)

Retrospective study of poxviruses diagnosed in cattle from Goiás State, Brazil (2010-2018) / Estudo retrospectivo de poxviroses diagnosticadas em bovinos no estado de Goiás (2010-2018)

A retrospective study of poxvirus infections diagnosed in cattle from Goiás state (GO), Brazil, from 2010 to 2018, was performed. All cases have been investigated by the GO Official Veterinary Service (Agrodefesa), from which technical forms and protocols of veterinary diagnosis laboratories were reviewed. In most cases, samples of oral or cutaneous tissues and/or swabs were submitted for virological diagnosis by polymerase chain reaction (PCR) and/or virus isolation. Thirty seven outbreaks/cases of vesicular disease were notified in cattle of 25 counties; in 33 cases the animals presented lesions clinically compatible with poxviruses. The etiology of 25 out of 33 outbreaks/cases was confirmed as poxviruses by PCR and/or viral isolation: 13 as bovine vaccinia virus (VACV), six as pseudocowpox virus (PCPV), five as bovine papular stomatitis virus (BPSV) and one coinfection (VACV and an Orf virus-like parapoxvirus). The laboratory confirmed that cases occurred mainly in dairy cattle (19/25) and during the dry season (22/25). In adult cattle, gross changes were observed mainly in the teats and udder and included vesicles, ulcers, crusts, papules and scars and varied of type, severity and affected region, depending on the poxvirus species. In calves, the main lesions were ulcers in the mouth and muzzle. Zoonotic lesions compatible with poxvirus infections were observed for all diagnosed poxviruses, affecting especially the hands of milkers and other farm workers. Our data demonstrate the sanitary and economic relevance of these diseases and the wide circulation of different poxviruses in cattle from GO.

Foi realizado um estudo retrospectivo das infecções por poxvírus diagnosticadas em bovinos do estado de Goiás (GO), entre 2010 e 2018. Todos os casos foram investigados pela Agência Goiana de Defesa Agropecuária (Agrodefesa). Foram revisados formulários técnicos e protocolos de laboratórios de diagnóstico veterinário. Na maioria dos casos, amostras de tecidos orais ou cutâneos e/ou swabs foram encaminhadas para diagnóstico virológico. Foram notificados 37 surtos/casos de doença vesicular em bovinos em 25 municípios; em 33 casos os animais apresentavam lesões clinicamente compatíveis com poxvírus. A etiologia de 25 de 33 surtos/casos foi confirmada como poxvírus por PCR e/ou isolamento viral: 13 como vírus vaccínia (VACV), seis como vírus pseudocowpox (PCPV), cinco como vírus da estomatite papular bovina (BPSV) e um caso de coinfecção (VACV e um parapoxvírus semelhante ao Orf vírus). Os casos confirmados laboratorialmente ocorreram principalmente em bovinos leiteiros (19/25) e durante a estação seca (22/25). Em bovinos adultos, alterações macroscópicas foram observadas principalmente nas tetas e úbere e incluíram vesículas, úlceras, crostas, pápulas e cicatrizes e variaram quanto ao tipo, gravidade e região afetada, dependendo da espécie do poxvírus. Em bezerros, as principais lesões foram úlceras na boca e focinho. Lesões zoonóticas compatíveis com infecção por poxvírus foram observadas em todas as poxviroses diagnosticadas, afetando principalmente as mãos dos ordenhadores e outros trabalhadores rurais. Nossos dados demonstram a relevância sanitária e econômica dessas doenças e a ampla circulação de diferentes poxvírus em bovinos de GO.

Rasgos clínicos y epidemiológicos de la viruela símica / Clinical and epidemiological features of monkeypox

La viruela símica (VS) es una enfermedad viral, zoonótica que afecta principalmente a los primates y se transmite a humanos. Dicho virus fue aislado inicialmente de un mono de laboratorio en la República Democrática del Congo en 1970 y a partir de allí, ha circulado en el continente africano, principalmente en República Democrática del Congo, Sudán del Sur, Camerún, República Centroafricana, Liberia, Nigeria, Sierra Leona y República del Congo; durante las últimas cinco décadas. Desde el año 2003 se reportaron casos fuera de África, específicamente en Estados Unidos, Reino Unido, Israel y Singapur; mientras que en mayo de 2022, la OMS; reportó un brote de VS humano en varios países de Europa y América, con más de 38000 casos en 93 países y cinco muertes en África, además de la ausencia de vínculos directos con países endémicos y un cambio en el patrón de transmisión; lo que conllevó al organismo a declarar el brote como emergencia de salud pública de interés internacional. La VS cursa con fiebre, cefalea, mialgias, linfadenopatia y lesiones dérmicas; y aunque la enfermedad no es fácilmente transmisible con tendencia a la curación espontánea; los casos observados actualmente no son típicos, con lesiones similares a las producidas por la viruela humana. La presente revisión tiene el objetivo de actualizar los conocimientos acerca de los rasgos clínicos y epidemiológicos de la VS, para comprender la presentación del brote actual y brindar herramientas que permitan diagnosticar y tratar eficazmente a los pacientes afectados(AU)

Monkeypox (MPX) is a viral, zoonotic disease that mainly affects primates and is transmitted to humans. This virus was initially isolated from a laboratory monkey in the Democratic Republic of the Congo in 1970 and since then has circulated on the African continent, mainly in the Democratic Republic of the Congo, South Sudan, Cameroon, the Central African Republic, Liberia, Nigeria, Sierra Leone, and Republic of the Congo; during the last five decades. Since 2003, cases have been reported outside of Africa, specifically in the United States, the United Kingdom, Israel, and Singapore; while in May 2022, the WHO; reported an outbreak of human MPX in several countries in Europe and America, with more than 38,000 cases in 93 countries and five deaths in Africa, in addition to the absence of direct links with endemic countries and a change in the pattern of transmission; which led the agency to declare the outbreak a public health emergency of international concern. MPX presents with fever, headache, myalgia, lymphadenopathy, and skin lesions; and although the disease is not easily transmissible with a tendency to spontaneous healing; the cases currently observed are not typical, with lesions similar to those produced by smallpox. This review aims to update knowledge about the clinical and epidemiological features of MPX, to understand the presentation of the current outbreak and provide tools that allow effective diagnosis and treatment of affected patients(AU)

La rabia es una enfermedad viral zoonótica, producida por un virus del genero Lyssavirus de la Familia Rhabdoviridae, cuya principal fuente de transmisión es la mordedura de animales a humanos. Es una enfermedad fatal y se han descrito casos por ciclos urbanos y rurales. El caso que reportamos es el de una joven de 22 años, quien ingresa por un cuadro de dolor de características neuropáticas en el miembro superior derecho, con antecedente de mordedura por un gato de varios meses atrás, hospitalizada por el servicio de Neurología por sospecha de lesión de plejo braquial, con resonancia de columna cervical y líquido cefalorraquídeo (LCR) normales, quien posteriormente presenta deterioro clínico tórpido a un proceso encefalopático que en pocos días la llevó a la muerte. Se confirmó que la paciente presentó una encefalitis por un virus de rabia. Expondremos cómo fue el manejo de la paciente y todos los nexos epidemiológicos.

Rabies is a zoonotic viral disease, caused by a virus of the genus Lyssavirus of the Rhabdoviridae family. Its main source is transmission from animals to humans bite. The disease is fatal and has been reported to occur in rural and urban cycles. This reported case is a 22-year old, who was admitted with symptoms of neuropathic pain in the right arm, with a history of being bitten by a cat a few months earlier. The patient was hospitalized in the Neurology Department for suspected brachial plexopathy, and normal spinal MRI and cerebrospinal fluid (CSF) were found. The patient subsequently presented encephalopathic decline that resulted in death within a few days. It was confirmed that the patient had encephalitis due to the rabies virus. We present the management of the patient and all epidemiological links.
