ABSTRACT
INTRODUCTION: Estimates of the number of individuals infected by severe acute respiratory syndrome coronavirus 2 are important for health planning and establishment of expectations regarding herd immunity. METHODS: Seven testing rounds of a serological survey were conducted at 1-week intervals between April 19 and May 31, 2020 in Teresina municipality. RESULTS Over the 7 weeks, serological positivity increased from 0.56% (95% confidence interval [CI]: 0.18%-1.30%) to 8.33% (95% CI: 6.61%-10.33%), representing 33-53 persons infected for each reported case. CONCLUSIONS: Serological screening may be an important tool for understanding the immunity of a population and planning community interventions.

É uma contribuiçäo para o fim da "violência institucional" que afeta milhares de mulheres e suas famílias, todos os anos, em estruturas com graves deficiências de atendimento, inadequaçäo de recursos humanos e materiais, ou relaçöes desumanas entre médico e paciente. Nos casos mais extremos, essas condiçöes condenam mulheres à morte. Os dados e avaliaçäo trazidos à tona säo apenas a etapa inicial, mas representam um passo importante na conquista de um atendimento mais digno e mais cidadäo nas maternidades de Teresina (RN)
