A 4-year-old boy may have a sexually transmitted disease after authorities say he found a used condom at an Atlanta area hotel and put it into his mouth.

The family of the unidentified 4-year-old boy says they were staying at the Wyndam Garden Inn in July when they discovered the child with the prophylactic in his mouth.

Ten days later they say the child had blisters around his mouth that were expected to go away but have since returned.

The boy’s grandmother Carmen Jones tells CBS Atlanta,

“I ran out the bathroom and my grandson had a condom in his mouth. — His tongue was in the condom and he was trying to blow it up. I immediately took it out of his mouth, —- he thought it was a balloon, thats why he was blowing it up.”

Jones also says she saw what she thought was semen on the condom but was stopped from taking the item in for testing by the hotel manager.

She says 24 hours later the boy began to vomit and showed signs of a possible STD including the trademark blisters.

“Little white blisters all on the top of his mouth, on his tongue, inside the mouth, inside the lip the bottom lip, it was all over.”
