Abstract
in English, Spanish

Coronaviruses cause respiratory and gastrointestinal disorders in animals and humans. The current SARS-CoV-2, the COVID-19 infectious agent, belongs to a subgroup called betacoronavirus including the SARS-CoV and MERS-CoV responsible for epidemics in 2002 and 2012, respectively. These viruses can also infect the nervous system due to their affinity for the human angiotensin-converting enzyme 2 (ACE2) expressed in neurons and glial cells. Infections with SARS-CoV, MERS-CoV, and now SARS-CoV-2 also produce neurological signs such as acute cerebrovascular disease, impaired consciousness, and muscle injury, as well as dizziness, hypogeusia, hyposmia, hypoxia, neuralgia, and hypoxic encephalopathy. For this reason, close attention should be paid to the neurological manifestations of COVID-19 patients.

Los coronavirus son una familia de virus que se caracterizan por producir afectaciones respiratorias y gastrointestinales en animales y en seres humanos. El actual SARS-CoV-2, agente infeccioso de la COVID-19, pertenece a un subgrupo denominado betacoronavirus del que hacen parte el SARS-CoV y MERS-CoV, virus responsables de epidemias en el 2002 y el 2012, respectivamente. Estos virus también pueden infectar el sistema nervioso debido a su afinidad con la enzima convertidora de angiotensina humana 2 (ACE2), la cual se expresa en neuronas y células gliales. Se ha demostrado que las infecciones con SARS-CoV y MERS-CoV, y ahora también con el SARS-CoV-2, ocasionan condiciones neurológicas como la enfermedad cerebrovascular aguda, la conciencia alterada y las lesiones musculares, así como mareos, hipogeusia, hiposmia, hipoxia, neuralgia y encefalopatía hipóxica. Por ello debe prestarse mucha atención a las manifestaciones neurológicas de los pacientes de COVID-19.
