State authorities began Tuesday the sanitizing of schools in order to protect students, teachers and staff for the restart of in school instruction.

In an event held in Mexicali Miguel Aleman elementary school Secretary of Education Gerardo Solis said 3,800 schools of Baja California will be sanitized.

In the project will work unions and other stakeholders along with the authorities, Sec. Solis said.

However, teacher union leaders had expressed concerns with the return to in school instruction.

Of the 65 sanitizing groups 20 will work in Mexicali schools.

The authorities will also provide items like soap, antibacterial gel, face masks and others.

Solis said all issues have been addressed for the appropriate return to schools on Jan. 17.

Secretary of Public Health Adrian Medina said the state has worked to make sure the return to schools is safe and orderly.

The return to school will be a hybrid one, as students will still be allowed to study from home. Also, parents are able to keep their children at home.

Some students will go to school on certain days while the others will attend the other days. Baja California has over 665,000 K-9 students.
