Momento de considerar otras arbovirosis luego del virus mayaro / Time to Consider Other Arbovirus Diseases after mayaro Virus

Introducción: En los últimos años, debido a los movimientos migratorios, se ha desarrollado una expansión de nuevas enfermedades, como chikungunya, zika, oropuche y mayaro. Caso clínico: Paciente que manifestaba síntomas de fiebre, cefalea y artralgias persistente. Después de un arduo estudio y eliminación de otras patologías se llega al diagnóstico de virus mayaro. El paciente residía en una zona nororiental del Perú. Se brindó tratamiento de soporte junto con hidratación, paracetamol 500 mg cada 8 horas y se indicó cita diaria para evaluación. El paciente evolucionó favorablemente a los pocos días. Conclusiones: La vigilancia, las pruebas y el control vectorial siguen siendo claves para prevenir la propagación de este tipo de virus. La posibilidad de que el virus mayaro se urbanice aún más. Se debe tener siempre en cuenta el diagnóstico diferencial de virus mayaro(AU)

Introduction: In recent years, due to migratory movements, an expansion of new diseases has developed, such as chikungunya, zika, oropuche and mayaro. Clinical case: Patient with the following symptoms: fever, headache and persistent arthralgia. After an arduous study and ruling out other possible diseases, we diagnose mayaro virus. The patient resided in a northeastern part of Peru. Supportive treatment was provided along with hydration; paracetamol 500 mg every 8 hours and daily appointment for evaluation was indicated. The patient evolved favorably within a few days. Conclusions: Surveillance, testing and vector control are still key to monitoring and preventing the spread of this type of virus. The possibility of mayaro virus becoming more urbanized is worthy of attention. The differential diagnosis of mayaro virus should always be considered(AU)

Prevalence of antibodies to equine alphaviruses in the State of Pará, Brazil / Prevalência de anticorpos para alphavirus em equinos do estado do Pará, Brasil

The State of Pará comprises 26% of Brazilian Amazon region, where a large diversity of arboviruses has been described. This study sought to assess the prevalence and distribution of hemagglutination inhibition (HI) antibodies against antigens of four alphaviruses (Togaviridae: Alphavirus ) from the species: Eastern equine encephalitis (EEEV), Western equine encephalitis (WEEV), Mayaro virus (MAYV), and Mucambo virus (MUCV) in 753 serum samples of horses in Pará State, Brazil. All investigated arboviruses were detected and indicate that horses are susceptible to these alphaviruses, and show evidences of their active circulation in farm animals in the Brazilian Amazon.(AU)

O estado do Pará corresponde a 26% da Amazônia brasileira, onde uma grande diversidade de arbovírus foi descrita. Este estudo procurou avaliar a prevalência e a distribuição de anticorpos inibidores da hemaglutinação (IH) contra antígenos de quatro alfavirus (Togaviridae: Alphavirus ), das espécies: Vírus da encefalite equina do leste (EEEV), Vírus da encefalite equina do oeste (WEEV), Vírus mayaro (MAYV) e Vírus mucambo (MUCV), de 753 amostras de soro de equinos no estado do Pará, Brasil. Todos os arbovirus pesquisados foram detectados, indicando que os equinos são suscetíveis a esses Alphavirus e mostrando evidências de sua circulação ativa em animais de fazenda na Amazônia brasileira.(AU)
