ABSTRACT
Resumo O artigo analisa o Índice da Segurança Sanitária Global (ISSG) à luz das respostas nacionais ao primeiro ciclo da pandemia da COVID-19. O ISSG classifica a capacidade dos países no enfrentamento dos riscos biológicos graves. O artigo examina os dados da pandemia de 50 países para avaliar o poder preditivo do ISSG. A ausência da vacinação determinou difusão da COVID-19 no primeiro ciclo da pandemia em 2020. Os indicadores dos países são correlacionados e demonstrados por estatística descritiva. A metodologia de aglomeração por clusters agrupa os países segundo a similaridade da composição etária. A principal restrição que pode ser atribuída ao ISSG diz respeito ao privilegiamento das variáveis biomédicas para a mensuração da capacidade institucional. O artigo evidencia que, paradoxalmente, o primeiro ciclo da pandemia teve um impacto significativo nos países teoricamente mais preparados, segundo o ISSG, para controlar a disseminação de doenças e oferecer mais acesso à assistência à saúde. O artigo assinala que durante o primeiro ciclo da pandemia, o setor saúde dependeu da cooperação dos governos na adoção do distanciamento social. O ISSG não considerou o papel das lideranças políticas que desafiam o risco sanitário severo por veto às medidas de distanciamento social.
Abstract This study approaches the Global Health Security Index (GHSI) according to the responses to the first cycle of the COVID-19. The GHSI ranks countries' institutional capacity to address biological risks. We analyzed data regarding the spread of COVID-19 pandemic in 50 countries to assess the ability of GHSI to anticipate health risks. The lack of vaccination determined the spread of the COVID-19 in the first cycle of the pandemic in 2020. Country indicators are correlated and demonstrated by descriptive statistics. The clustering method groups countries by similar age composition. The main restriction that can be attributed to the GHSI concerns the preference of biomedical variables for measuring institutional capacity. Our work shows that the pandemic had a significant impact on better-prepared countries, according to the GHSI, to control the spread of diseases and offer more access to health care in 2020. This paper points out that the health sector depended on the cooperation of governments in the adoption of social distancing during the first cycle of the pandemic. The GHSI failed to consider the role of political leaders who challenge severe health risks by vetoing social distancing.

El objetivo principal de este trabajo es describir los principales aspectos biológicos, epidemiológicos y clínicos,con especial énfasis en la fisiopatología, ocasionado por el SARS-CoV-2.El Coronavirus 2 del Síndrome Agudo Respiratorio Severo,es un orthocoronavirinae, del grupoI V, pertenecientes al género betacoronavirus,que causa la actual enfermedad pandémica definida por la Organización Mundial de la Salud (OMS)(2020), como COVID-19.Esta es considerada por los expertos mundiales como una infección viral emergente. Su origenes veterinario y su transmisión zoonótica, a partir de virus que tienen como reservorios a murciélagos y como hospedador intermediario al pangolín, desde el cual se infiere que pudo adaptarse al ser humano, para transmitirse de persona a persona,mediante gotitas respiratorias y secreciones nasales contaminadas con partículas altamente infecciosas. No se descarta la transmisión fecal-oral. La enfermedad posee un periodo de incubación de 2 a 14 días (promedio:5,2 días) y hasta ahora las medidas de prevención y control más eficientes son la cuarentena social obligatoria, el uso de tapabocas, lavado de manos con agua y jabón por al menos 20 segundos,o con productos en gel con alcohol al 70%, mantener una distancia mínima entre las personas de 2 metros. Lo aprendido de los otros dos betacoronavirus humanos relacionados, causantes de las epidemias previas: SARS-CoVen 2002-2003 y el MERSen 2012 ,permiten encarar de mejor forma la actual pandemia(AU)
The main objective of this work is to describe the main biological, epidemiological and clinical aspects, with special emphasis on pathophysiology, caused by SARS-CoV-2. Coronavirus 2 of Severe Acute Respiratory Syndrome is a member of group IV orthocoronavirinae, belonging to the betacoronavirus genus, which causes the current pandemic disease defined by the World Health Organization as COVID-19. This is considered by world experts as an emerging viral infection. Its origin is veterinary and its zoonotic transmission, from viruses that have bats as reservoirs to pangolin an as an intermediate host, from which it is inferred that it could have adapted to the human being, transmitted from person to person by means of respiratory droplets, and highly infectious contaminated nasal secretions Fecal-oral transmission is not ruled out. The disease has an incubation period of 2 to 14 days (5.2 days in mean), and until now the most efficient prevention and control measures are the obligatory social quarantine, the use of face masks, hand washing with soap and water for at least 20 seconds, or with products in gel with 70 alcohol, keeping a minimum distance between people of 2 meters. What has been learned from the other two related human betacoronaviruses that caused the previous epidemics: SARS-CoV in 2002-2003 and MERS in 2012, allow us to better face the current pandemic(AU)
