High-touch

The U.S. Centers for Disease Control and Prevention recommends cleaning all “high-touch” surfaces every day, like phones, keyboards and computers.

The new home is more than one-thousand square meters. Work crews used almost ninety-one-thousand kilograms of steel to build it. About one-fifth of the steel is covered with a chemical that kills bacteria, mold and other organisms. A Massachusetts company, AgION Technologies, produces the chemical. The heating, airflow and cooling systems all are made with the treated steel. So are food preparation surfaces and other "high-touch" areas, along with the roof.

All high-touch surfaces must be disinfected.
