Resumen


Resumen

Los coronavirus (CoV) son patógenos que se transmiten a los animales y a los humanos; tienen una distribución mundial. Se han identificado seis tipos de CoV como causantes de enfermedades humanas: cuatro causan síntomas respiratorios leves, mientras que dos tipos, el síndrome respiratorio del Medio Oriente (MERS) y el síndrome respiratorio agudo severo (SARS), han causado epidemias con altas tasas de mortalidad. Los coronavirus humanos causan el resfriado común, provocan infecciones de las vías respiratorias inferiores y están implicados en la gastroenteritis infantil. En la actualidad, el coronavirus SARS-CoV-2 se ha transmitido entre especies, incluido el hombre, y tiene la característica de ser un virus respiratorio muy virulento que causa la enfermedad conocida como COVID-19, la cual hasta la fecha no tiene un tratamiento médico autorizado. La Organización Mundial de la Salud anunció que el brote de COVID-19 ha pasado de ser una emergencia sanitaria a una pandemia. Por lo tanto, los objetivos de este documento son mencionar las generalidades de los coronavirus (estructura, genoma, mutación y recombinación), la descripción epidemiológica, el mecanismo de transmisión entre animales y humanos, la patogénesis y la terapéutica.

Abstract

Coronaviruses (CoV) are pathogens that are transmitted to animals and humans; they spread around the world. Six types of coronavirus have been identified as causing human disease: four cause mild respiratory symptoms, while two types, the Middle East Respiratory Syndrome (MERS) and the Severe Acute Respiratory Syndrome (SARS), have caused epidemics with high mortality rates. Human coronaviruses cause common cold, lead to lower respiratory tract infections and are involved in pediatric gastroenteritis. Currently, the coronavirus SARS-CoV-2 has been transmitted between species, included humans, and is a very virulent respiratory virus, causing the disease known as COVID-19, which to date, has not an authorized medical treatment. The World Health Organization announced that the outbreak of COVID-19 has been upgraded from a health emergency to a pandemic. Therefore, the objectives of this paper are to mention the basic concepts of coronavirus (structure, genome, mutation and recombination), its epidemiological description, animal-human transmission mechanism, pathogenesis and therapeutics.
