Fact check: Is it REALLY a bad idea to kiss newborn babies?

A few terrible cases recently have prompted concerns about the wisdom of kissing small babies, with parents worrying that their children could catch herpes and become ill – or even die. But just how easily is this common virus passed from grown-ups to little ones?

Herpes can be fatal for babies

Around 67 percent of the population is infected with the Herpes Simplex Virus 1 (HSV-1), whether they realise it or not. Many people never show symptoms of this virus, which can mean they don’t realise they might be at risk of infecting others.

Jeff Gober’s daughter Mallory died as a result of HSV-1 when she was just three weeks old.

“Nobody ever kissed her on the mouth,” Jeff wrote on parenting site Cafe Mom. “In spite of that, she caught HSV-1 within her first week of life and we had to watch her die slowly for nearly two weeks. Mallory could not keep her hands out of her mouth and eyes and she was constantly sucking on her fingers, so it’s almost certain that the virus got onto her hands at some point. It is possible to be contagious even without an active cold sore.”

“The herpes simplex virus spreads between people, usually through contact with saliva or direct contact with a blister,” the Victorian Government’s Better Health channel says. “The most infectious time is in the first few days when the blister is forming. Sometimes, people can pass the virus to others when they have no symptoms. This is because the virus may be lying dormant in the skin cells of the lips.”

“Stay away from babies”

Lucy Kendall’s 12-day-old baby, Oliver, spent eight days in a high-dependency unit, and a total of 21 days in the hospital after contracting neonatal herpes. Thankfully Oliver pulled through, but the family got the fright of their lives.

“Me and my partner are clear of the herpes virus and nobody kissed Oliver,” Lucy explained on Facebook, warning people to stay away from babies if they have a cold sore or blisters.

Sydney couple Jessica and Angus Buchanan’s baby boy very sadly died as a result of Herpes Simplex Virus 1 when he was just 11 days old.

The couple are not sure how their baby came into contact with the virus but hope to spare other families similar heartbreak by encouraging optimal hygiene and caution when coming into contact with small babies.

“If me telling his story encourages just one person to wash their hands extra well, to take extra precautions around babies or to avoid contact completely if they feel the tingle of a cold sore on their lips – then it will have been worth it,” Jessica said on Facebook.

The riskiest time

Babyology spoke to nurse, neonatal expert and CPR Kids operations manager Nicole Ovens to find out more, and she confirmed what these parents have stressed.

“Many people are infected with herpes simplex virus type 1 (cold sore virus),” Nicole said. “In some people, the virus lies dormant without ever progressing to symptoms. These people have no idea they have the virus.”

“In others, painful blisters erupt, ulcerate and weep in and around the mouth, lips, nose and eyes periodically when the virus becomes active.”

Nicole says the virus is most dangerous and contagious when blisters or legions are present and that “during this period it is important that infants are not kissed.”

Frequent hand-washing is vital

Nicole says vigilant hygiene is very, very important when tiny babies are involved – cold sore or not. Err on the side of caution.

“There are other very important considerations that will protect an infant and they must also all be strictly adhered to. First and foremost – thorough and strict hand washing is paramount. Food and eating utensils must not be shared. Visitors or children with active lesions should be advised not to have contact with the infant during this time.” 

For parents who are worried about their children coming into contact with the herpes virus, it’s a great idea to chat to your family doctor about your concerns – and discuss your options for treatment and the best ways to keep your kids safe from the virus.

In conclusion …

 So, is it a bad idea to kiss infants? It’s a very hard one to answer.

If the person doing the kissing had HSV1, then in some cases it might be a bad idea.

To mitigate risk, maintain excellent hygiene and know that those very early weeks are when babies are most at risk from serious complications if they contract HSV1.

And if you know that you or someone close to you is carrying HSV1 and you have any worries about your newborn’s health in those early weeks, err on the side of caution and pop into your trusty GP to get them double-checked. And even if you are not aware of HSV1 in your circle and you have worries about your baby’s wellbeing, seek medical advice.
