So how can you keep you and your family healthy?

The CDC said to clean things you touch frequently every day. Focus on counters, tabletops, doorknobs, bathroom fixtures, toilets, phones, keyboards, tablets and bedside tables.

To do it right, it may take a two-step process: cleaning with detergent and water if it is dirty, then disinfect the surfaces using one of the products the CDC has approved.
