School Reopenings, Mobility, and COVID-19 Spread: Evidence from Texas

Charles J. Courtemanche, Anh H. Le, Aaron Yelowitz & Ron Zimmer:

This paper examines the effect of fall 2020 school reopenings in Texas on county-level COVID-19 cases and fatalities. Previous evidence suggests that schools can be reopened safely if community spread is low and public health guidelines are followed. However, in Texas, reopenings often occurred alongside high community spread and at near capacity, making it difficult to meet social distancing recommendations. Using event-study models and hand-collected instruction modality and start dates for all school districts, we find robust evidence that reopening Texas schools gradually but substantially accelerated the community spread of COVID-19. Results from our preferred specification imply that school reopenings led to at least 43,000 additional COVID-19 cases and 800 additional fatalities within the first two months. We then use SafeGraph mobility data to provide evidence that spillovers to adults’ behaviors contributed to these large effects. Median time spent outside the home on a typical weekday increased substantially in neighborhoods with large numbers of school-age children, suggesting a return to in-person work or increased outside-of-home leisure activities among parents.

which pushed Dane County this week not to calculate its percentage of positive tests — a data point the public uses to determine how intense infection is in an area.   

While positive test results are being processed and their number reported quickly, negative test results are taking days in some cases to be analyzed before they are reported to the state.

The department said it was between eight and 10 days behind in updating that metric on the dashboard, and as a result it appeared to show a higher positive percentage of tests and a lower number of total tests per day.

The department said this delay is due to the fact data analysts must input each of the hundreds of tests per day manually, and in order to continue accurate and timely contact tracing efforts, they prioritized inputting positive tests.

“Positive tests are always immediately verified and processed, and delays in processing negative tests in our data system does not affect notification of test results,” the department said in a news release. “The only effect this backlog has had is on our percent positivity rate and daily test counts.”

Staff have not verified the approximately 17,000 tests, which includes steps such as matching test results to patients to avoid duplicating numbers and verifying the person who was tested resides in Dane County.
