ABSTRACT The covid-19 pandemic brought up several economic and socio-environmental issues, including the fragility of the Brazilian population given the current sanitary condition of the country. Understanding how this has been behaving has become fundamental for the basis of public policies aimed at controlling the pandemic. Therefore, this study aimed to know the relationship of vulnerability related to the lack/inefficiency of sanitation and the spread of covid-19, considering the 27 Federative Units of Brazil. For this, health, basic sanitation, and sociodemographic variables were used, and Factor Analysis was applied to calculate the Covid-19 Health Vulnerability Index. The analysis showed an inverse correlation between health and sanitation variables, attesting that the higher the proportion of the population with access to sanitation services, the lower the incidence rate of covid-19. The results showed that the states of the North and Northeast regions have greater vulnerability to covid-19 when compared to the others, derived from the low reach of sanitation services, especially in the state of Pará, which ranked first in the national vulnerability ranking. covid19 covid 19 covid-1 socioenvironmental socio environmental issues country Therefore lackinefficiency lack inefficiency covid19, 19, 2 Brazil used Covid19 Covid Covid-1 Index services covid19. 19. others Pará ranking covid1 1 covid- Covid1 Covid-

RESUMO A pandemia de covid-19 trouxe à tona diversas questões econômicas e socioambientais, dentre elas a fragilidade da população brasileira diante da atual condição sanitária do país. Assim sendo, este estudo se propôs a conhecer a relação de vulnerabilidade relacionada à falta/ineficiência do saneamento e a disseminação de covid-19, considerando as 27 Unidades Federativas do Brasil. Para isso, foram utilizadas variáveis de saúde, saneamento básico e sociodemográficas e aplicada a metodologia de Análise Fatorial para calcular o Índice de Vulnerabilidade Sanitária à Covid-19. A análise apontou correlação inversa entre variáveis de saúde e saneamento, atestando que quanto maior a proporção da população com acesso aos serviços de saneamento, menor a taxa de incidência de covid-19. Os resultados mostraram ainda que os estados das Regiões Norte e Nordeste possuem maior vulnerabilidade à covid-19 quando comparados aos demais, ocasionada pelo baixo alcance dos serviços de saneamento, com destaque para o estado do Pará, que ocupou o primeiro lugar no ranking nacional de vulnerabilidade. covid19 covid 19 covid-1 socioambientais país sendo faltaineficiência falta ineficiência covid19, 19, 2 Brasil isso Covid19.
