One in four teachers at greater risk from coronavirus

These teachers and instructors, about 24% of the total, suffer from health conditions such as diabetes, heart disease or obesity, or are older than age 65, which make them more vulnerable, the Kaiser Family Foundation report found.

The share of teachers at high risk based on criteria identified by the Centers for Disease Control and Prevention is the same as for workers overall, Kaiser said. Schools face the challenge of high traffic and tight quarters, which could make social distancing difficult.
