Without a vaccine or treatment available, non-pharmaceutical interventions (NPIs) such as closing of venues, staying home, minimizing contact with others, social distancing, and wearing of face coverings are critical to preventing spread. However, these NPIs do cause disruption to normal society. In order to manage risks of relaxing these interventions, a coordinated effort across local government, public health experts and business and community leaders is paramount. Phased-in approaches to the reopening of schools should be approached responsibly and driven by available data and the professional judgement of public health and health experts alike.
We are committed to safely moving forward together, but that commitment must coexist with awareness that reopening too quickly poses health risks and educational setbacks.
On June 11, 2020, Harris County unveiled its COVID-19 Threat Level System. The system comprises key metrics that the County uses to monitor the spread of COVID-19, the ability to contain further spread, and the ability to treat those who have severe health outcomes as a result of COVID-19.
The threat levels are defined by five sets of indicators: case trends, percentage of COVID-positive hospital population (ICU and general beds considered individually), hospitalization trends (ICU and general beds considered individually), COVID-19 test positivity rate, and the availability of countermeasures. These metrics will be maintained consistently on readyharris.org.
If any one of these indicators is not at a satisfactory level, our ability to manage the virus’s impact on our community is diminished. For example, if disease transmission indicators are at lower levels but our COVID-19 hospital population is high, we must continue to maintain preventative measures to ensure that reopening schools does not overwhelm the healthcare system. If our COVID-19 hospital population is low, but new positive cases of COVID-19 are increasing, we must continue preventative measures to control the spread. While there are other factors, inputs, and measures that are being monitored by Harris County on an ongoing basis, use of the following indicators provides key measures for an overall assessment of the community’s threat from COVID-19. To move down the ladder of the threat level system, all the thresholds for the indicators must be met sustainably.
While some districts may be in areas of the county that have fewer cases or lower positivity rates or may have some school campuses in a neighboring county, the indicators are reflective of the virus’s impact on our collective Harris County community. All our communities are served by our hospital system and case investigation/contact tracing teams. Hotspots anywhere in Harris County impact our ability to manage the virus’s impact everywhere. Unlike a state with physically distanced cities, we in Harris County live in a profoundly interconnected and physically proximate community, and while our student populations may be limited to certain areas of the county, school teachers, staff and parents live and travel throughout our community.
The recommendations for schools offered in Part 2 are based on the Harris County Threat Level at a given time. Harris County COVID-19 Threat Level System*
