Covid-19: fisiopatología, historia natural y diagnóstico
DOI:
https://doi.org/10.37135/ee.04.11.13Resumen
SARS CoV-2 se transmite principalmente a través de la vía aérea. La media del tiempo desde la exposición hasta la presentación de la sintomatología es de 5 días. Los pacientes infectados pueden permanecer asintomáticos o tener un amplio espectro de manifestaciones como: fiebre, tos seca y malestar general. Aproximadamente, el 20% de pacientes con la COVID-19 requiere hospitalización (10% en área general, el 5% requiere cuidados intermedios y el 5% restante ingresa a cuidados intensivos debido a su estado de gravedad). Los exámenes de laboratorio y radiológicos muestran anomalías de común presentación, pero inespecíficas. El diagnóstico es a través de la prueba de reacción en cadena de polimerasa de transcripción inversa cuando detecta SARS CoV-2. El objetivo de la revisión que se presenta es sintetizar elementos importantes relacionados con la fisiolopatología, manifestaciones clínicas y diagnóstico de la COVID-19.
