Presentamos a un paciente masculino de 51 años proveniente de Sudáfrica que comienza con síntomas respiratorios a las 48 horas de su llegada a la Ciudad de México. Durante su estancia en urgencias se obtuvo prueba de antígeno y RT-qPCR para SARS-CoV-2 positivas, con mínima alteración de parámetros de laboratorio y sin evidencia de afección pulmonar por tomografía. El paciente presentó evolución favorable y fue dado de alta seis días después. El día 29 de noviembre se recibió la notificación del Instituto de Diagnóstico y Referencia Epidemiológicos (InDRE) de que se trataba de la variante Ómicron del virus SARS-CoV-2.]]></p></abstract>

This variant draw attention for its high number of mutations on the S protein. We present a 51 year old male, from South Africa who started with respiratory symptoms 48 hours after his arrival to Mexico City. During his stay at the ER a positive antigen and positive RT-qPCR were obtained. Minimal laboratory alterations were observed with no evidence of lung involvement on the CT scan. The outcome was favorable and was discharged six days later. On November 29, a notification from InDRE was received, reporting that the sequence obtained was compatible with SARS-CoV-2 Omicron variant.]]></p></abstract>
