POPLAR BLUFF, Mo. (AP) — A southeast Missouri teacher isn’t letting a bite from a poisonous snake keep her off the job.

The Poplar Bluff Daily American Republic reports that Katelyn Campa recovered quickly after being bitten by a copperhead snake on Sept. 2. In fact, she was back in class the next day. She used the incident as an opportunity to teach her Poplar Bluff fifth-graders about snakes and snake safety.

Campa had been working late and walked outside to meet a friend, who was bringing her supplies.

As she opened a back door of the school for her friend, Campa was bitten on the toe by a small copperhead. She was treated at a hospital and released that night. Her principal couldn’t persuade her to take the next day off.
