(WHDH) — At least eleven school districts have closed in Texas due to a flu outbreak.
Each school that closed had at least 20% of their student population call out sick on Wednesday.
Gunter School District said they had 253 of their students out sick, which is about 30% of their student population.
A superintendent said closing the district was necessary to stop the outbreak. Gunter School District is taking a week off to deep clean all of their facilities.
School nurses said several students had their flu vaccine, but officials say it is only expected to be about 10% effective this season.
