From the Document: "The current literature and guidance suggest that we provide testing to both symptomatic and asymptomatic persons, since a large percentage of infected persons are asymptomatic. We plan to increase testing capacity substantially to support geographic areas of the city with low testing saturation. To identify areas of need, Houston Health Department (HHD) has used a data-driven strategy to identify and prioritize geographic areas for testing. Access and equity were the core philosophies undergirding the HHD testing strategy. Testing penetration was geographically overlaid with areas with vulnerable populations under the Federal Poverty Level (FPL) that are most likely to have the poorest outcomes from a COVID [coronavirus disease 2019] [sic]. We plan to achieve: a) Testing at a level of 2% of our population size (minimum 46,000 tests/month); b) Decline in positivity rates - Less than 10% of all tested are positive."
