Abstract

Conocer y descifrar los cambios o mutaciones que experimentan los virus en el tiempo es crucial para desarrollar las estrategias de vigilancia epidemiológica del SARS CoV 2. El virus tiene un ARN monocatenario y posee mecanismos de evolución llamados mutaciones, las cuales le confieren eficacia biológica para aumentar su transmisibilidad, modificar su patogenicidad, con lo cual evaden la inmunidad del huésped, modificando así la respuesta antigénica. Hace algún tiempo se creía que los cambios en los coronavirus eran más lentos que en la mayoría de los ARN virus, pero hoy se han observado mutaciones relevantes en SARS CoV-2 (1).

SARS CoV-2真的是人畜共患病吗?

了解和解读病毒随时间的变化或突变对于制定SARS CoV 2的流行病学监测战略至关重要。病毒具有单链rna，并具有称为突变的进化机制，这使其具有生物效率，以增加其传播能力，改变其致病性，从而逃避宿主的免疫，从而改变抗原反应。一段时间以前，人们认为冠状病毒的变化比大多数rna病毒慢，但今天在SARS CoV-2中观察到相关突变(1)。

期刊介绍： The Journal MVZ Córdoba is an open access international scientific journal financed and edited by the University of Córdoba (Colombia). The journal publishes quarterly, continuously in PDF, XML, Epub, original articles, literature reviews, brief communications and clinical cases, peer-reviewed (double-blind) in Spanish and English, which are related to the agricultural and veterinary sciences. The journal is directed to natural and legal persons of veterinary medicine, animal husbandry, public health, epidemiology, aquaculture, biology, basic biomedical sciences and biotechnology and constitutes a space for academic and scientific discussion around the work of professionals in Veterinary Medicine and Zootechnics. Four-monthly publication. "The Journal MVZ Córdoba supports the policies for registration of clinical trials of the World Health Organization (WHO) and the International Committee of Medical Journal Editors (ICMJE), since it recognizes the importance of these initiatives for international registration and dissemination. of information about clinical studies, in open access. As a result, since 2007, the journal MVZ Córdoba only publishes clinical research articles that have received an identification number in one of the Clinical Trial Registries validated by the criteria established by WHO and ICMJE, whose addresses are available in the ICMJE website. The identification number is recorded at the end of the summary. "
