HOUSTON, Miss. (WTVA) - One family is doing its part to protect people from the coronavirus.

Amy Gardner and her family travel to sanitize homes and churches around Chickasaw County.

“We really wanted to do something, so we decided that we were going to get out on the frontline,” she said.

Gardner said she and her son have severe asthma and are high-risk for the coronavirus.

She, her husband and son completed online courses to become certified environmental cleaners.

“We decided, even though we got this underlying condition, we are going to get out and do everything we can for our county and our state.”

Her family sterilizes high-touch surfaces with hospital-grade chemicals. They spray inside churches and homes using fogging machines recommended by the CDC.

Depending upon the number of people who enter a building, Garnder estimates the cleaning will last up to six or eight weeks.

Gardner warns anyone who is not certified should not use fogging machines and chemicals. They could create more harm than good, she said.
