Nos sorprendió con una noticia grande, de interés para todos, de fuera de México y posteriormente también aquí. El año 2020 inició con la noticia de que en la ciudad de Wuhan en China, había un brote de neumonías virales que provocaba que la gente buscara atención médica y cuya evolución no era igual a las infecciones respiratorias agudas conocidas. Uno de los primeros médicos, el oftalmólogo Li Wenliang notó el alto número de pacientes con síntomas parecidos y en diciembre del 2019 comentó que la enfermedad podría ser causada por un virus nuevo. El 7 de febrero del 2020 el Dr. Wenliang había muerto por la constante exposición a tal virus. Diez días después siguieron las muertes de otros médicos, el Dr. Liu Zhiming y el Dr. Xu Depu quien fuera director del hospital médico de la ciudad Ezhou en Hubei, además de muchos pacientes. Desde entonces, y hasta el 24 de marzo hay casi 400,000 infecciones y cerca de 20,000 muertos en todo el mundo, sin que parezca que los contagios comiencen a disminuir. Pero ¿qué es lo que ocurre cuando el virus infecta? ¿Por qué es importante saber si alguien está infectado? ¿En qué consiste la prueba clínica? ¿Qué tipo de vigilancia epidemiológica se lleva a cabo en México? En este artículo se contestamos estas preguntas.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract This new decade has started ominously. The year 2020 began with the reports from Wuhan, China, of people seeking medical attention for viral pneumonia whose evolution deviated from known acute respiratory infections. One of the first doctors to raise the alarm, ophthalmologist Li Wenliang, noticed the high number of patients with similar symptoms, and in December 2019 mentioned to his colleagues that the disease could be caused by a new virus. On February 7, 2020, Dr. Wenliang died from constant exposure to this novel infectious agent. Ten days later, the deaths of other doctors, Dr. Liu Zhiming and Dr. Xu Depu who was director of the Ezhou City Medical Hospital in Hubei, was reported, together with that of many patients. Since then, and according to the accounting kept by Johns Hopkins University, up to March 30 there have been more than 750,000 confirmed infections and more than 36,000 deaths worldwide, without signs of a slowdown in the rate of infection. In this article we address various questions that arise when an event of this magnitude occurs, for example: What happens during viral infection? How does a previously harmless virus become a danger to man? How can you tell if the new virus was intentionally manipulated or not? Why is it important to know if someone is infected? What does the clinical test consist of? What type of epidemiological surveillance is carried out in Mexico?]]></p></abstract>
