*Webinar Abstract*

In a partnership of the Observatory of Respiratory Syndromes of the Federal
University of Paraíba, the Paraíba State Government and SCIENCE, the
epidemiological survey "Continuar Cuidando PB", a household-based sample
survey conducted in November and December 2020, collected sociodemographic
and symptoms data together with testing of residents for the diagnosis of
COVID-19. The total sample of 394 census enumeration areas (CEAs) was
stratified into four macro-regions of the state and subdivided within these
strata for collection over eight weeks, with equal collection load per week
in each stratum. In each selected CEA, a concurrent household listing and
sampling protocol was applied using a combination of Bernoulli plus inverse
sampling. Listing and sampling of new households stopped when the number of
residents tested with the RT-PCR test in interviewed households totaled 25
or more. When a household was sampled and agreed to participate, all
residents were tested, even if this meant that the total number of tested
individuals in a selected CEA would go above 25. This protocol enabled
speedy performance of the data collection, the release of partial results
every two weeks, and strong linkage between the data obtained in the
socioeconomic questionnaires with the results of the tests performed for
COVID-19. Data collection was performed in partnership with teams from the
municipal and state health departments, who were responsible for the
application of rapid (finger blood sample) and RT-PCR tests, for the timely
return of results to the tested participants, and for the provision of
appropriate care services to all who tested positive for the disease. All
health and safety precautions were taken to protect the team of
interviewers and health professionals involved in the data collection, as
well as the residents of the selected households who participated in the
survey.

Keywords: Serum-prevalence survey; inverse sampling; Bernoulli sampling;
household listing; health surveillance.
