CHICAGO (WLS) -- In the last several days, medical experts have been warning parents about a poison which could be in your home. They call it a silent epidemic that people have forgotten: lead paint.
Health experts recently recognized "National Lead Poisoning Prevention Week" and now hope to encourage parents to have children and homes tested for lead.
The ABC7 I-Team has followed one local child's lead poisoning case for years. Now, he's sharing his story to help others.
"I would like to keep them away from lead paint," said 3rd grader Marshall Sontag, who is warning his fellow students about the dangers of lead paint. "If you get it, it's bad."
He was assigned to write a report about something he was passionate about.
"A lot of Marshall's classmates were picking Minecraft or Fortnight. Marshall decided to pick lead poisoning," said Marshall's mom, Caitlin Szontagh.
That's because Marshall is a lead poisoning survivor. When he and his brother were preschoolers, they had their blood drawn and tested every week after being exposed to lead paint in their Berwyn rental apartment.

The I-Team has followed the boys' case since 2017, when an X-ray showed paint chips in Marshall's system and his lead level reached 60.
The CDC says NO level of lead is safe. Even low levels of lead in the blood have been shown to impact IQ, ability to pay attention, and academic achievement. Marshall has been diagnosed with intellectual delays as a result of lead poisoning.
"He's constantly moving, running, jumping," his mom said. "He's a little behind in school and we're doing all we can to get him the proper support he needs."
"Getting that blood test is paramount to finding out whether or not there's been an exposure," said Kert McAfee, Childhood Lead Poisoning Prevention at the Illinois Department of Public Health.
Approximately 60% of housing units in Illinois were built prior to 1978, when lead paint was banned. According to the Illinois Department of Health's latest numbers, more than 7,000 children had lead found in their blood in 2019.
"Every single zip code in Chicago has been determined to be a high-risk area," McAfee said.
Experts say you should test your child for lead, especially if you live in a home or apartment built before 1978.
You can also have a licensed professional check your home, and contact your county health department if lead is found.
