A Douglas County elementary school worked to contain a stomach virus that sickened more than 100 students this week.

Custodians have been working hard to sanitize South Douglas Elementary School, Principal Casey Duffey told Channel 2 Action News. The school is also trying to make sure students practice good hygiene, such as washing their hands often.

By Thursday, only one ill child had left school, Duffy said. That was a far cry from earlier in the week when a number of students were stricken.

“I’m sure it was over one hundred,” Duffey said, “and that includes the ones we sent home yesterday.”

Some parents kept their children home Thursday after South Douglas Elementary sent home a letter Wednesday alerting them to the stomach bug, Channel 2 said. Rebecca Farmer said her daughter came down with the virus Tuesday.

“She said she felt sick and sure enough she started getting sick, and it pretty much lasted throughout the whole

day,” Farmer said. But by Wednesday, her daughter felt better, she told Channel 2.

The school system nurse came out and helped take temperatures, the principal said. “We just worked with students and parents, and parents were very good to come up here and get students throughout the day as we needed them to,” Duffey said.

The Douglas County health department told Channel 2 that a two- to three-day virus struck the school, and that it should be over by Monday.
