Claire Henderson shared a shocking photo of her newborn on Facebook; her daughter’s face was covered in sores, apparently because of a kiss she got from a visitor.

Henderson said little Brooke contracted the herpes virus from the visitor through a kiss on the lips. Even though the visitor didn’t appear to have a cold sore at the time, the virus was still transmitted, Henderson said.

When Brooke was born, a friend warned Henderson her that cold sores could be deadly to a newborn younger than 3 months old, so when Henderson noticed a small red bump on her baby’s lip, she immediately took the child to a doctor.

Doctors put Brooke on an antiviral drip for three days to get rid of the infection.

"She was VERY lucky, all her tests came back clear," Henderson wrote on Facebook. "The moral of the story is DO NOT let anyone kiss your newborn's mouth, even if they don't look like they have a cold sore."
