For Schools in Small Towns, a Few New COVID Cases Can Spark Drastic Changes

Sutton had just 10 new coronavirus cases in 14 days, but with a small population, that bumped the small Massachusetts town into the highest risk category, which impacts school reopening plans

In a larger community, a few coronavirus cases may not force students to learn remotely, but in a town with a smaller population, they could change the course of an entire school year.

Massachusetts' new COVID-19 dashboard is an easy, color-coded way to see which communities are experiencing spikes in positive test results.

But the so-called "red" communities can often have vastly different case numbers.

For example, of the nine cities and towns currently in the highest risk category, Lynn has 236 cases over a two-week period, while Sutton has just 10 cases in the same time frame.

"So, if you have 10 cases in a small community, that's going to give you a much higher rate of infection than 10 cases in a large city," said Dr. Daniel Karitzkes, the chief of the Infectious Diseases Division at Brigham and Women's Hospital.

He says epidemiologists like to work with rates of infection to get a clearer picture of the potential of exposure in each community.

"We have to remember these rates change over time, and we can expect fluctuations where there may be bumps and valleys," Karitzkes said.

Those fluctuations can be bigger with smaller numbers to work with, like in Sutton, with a population of under 10,000 people.

And that can be tricky when basing decisions on school reopening plans partly on community coronavirus rates.

"I think the superintendents really do need to take into account the rate of infections, not just the total number of infections," said Karitzkes.

"We will work with the local public health department to determine if we can stay in school," said Theodore Friend, superintendent of Sutton Public Schools. "With so few cases, we should be able to make an informed decision for our students and staff."

"No individual tool is going to give you the complete picture, and no particular tool is precise or fool-proof, so we really need to look at the total information available," Karitzkes said.

In Sutton, there are currently two weeks of professional development for teachers before students are scheduled to start in a hybrid model Sept. 14.
