TOPEKA, Kan. (AP) — Gov. Laura Kelly is closing all K-12 schools through the end of the semester, moving instruction online as the state responds to the coronavirus pandemic.

Kelly's Tuesday afternoon announcement comes as several school districts already had extended spring breaks and colleges and universities had moved to online instruction for the rest of the school year.

Officials said Kansas has at least 18 confirmed cases of the coronavirus as the pandemic continues to spread in the state.

Kelly also said that starting Monday, most of the 18,000 state workers under her supervision will be directed to stay at home for two weeks so agencies can plan for having some work from home and place others on paid administrative leave.

Earlier Tuesday the House approved a bill to give laid-off workers another 10 weeks of unemployment benefits as employees face virus-related business closures.
