Mother's Cold Sore Virus Killed Newborn After Medical Staff Dismissed Her Ulcers as Hormonal

A mother has shared her devastating experience after her newborn daughter died from the herpes simplex virus (HSV-1), commonly known as the cold sore virus, after she was repeatedly told by medical professionals that her own painful mouth ulcers were a result of hormonal changes.

Meg Edmonds, 22, developed sores on her lips and in her mouth on the same day she gave birth to her daughter, Magnolia, in February. She inquired whether the ulcers could be a cold sore, but was reassured by health workers that they were hormonal or a sign she needed to drink more water.

Tragically, ten days later, Magnolia, who was known as Maggie, died in intensive care from disseminated neonatal herpes. Ms. Edmonds believes she passed the virus to her daughter, a realization that has been profoundly difficult to bear. "The virus came from me, which is so devastatingly hard to live with," she stated. "No one in our family or friends knew a cold sore could kill a baby. I didn't even know cold sores were caused by the herpes virus until after she died."

Magnolia was born on February 1, a younger sister to Cordelia, who is two and a half. For the first two days of her life, Maggie was alert and feeding well. However, by the third day, she became lethargic and began to struggle with feeding.

Over the following week, Maggie developed breathing difficulties, a weak, high-pitched cry, a rash across her chest, and a sore eye. Her condition worsened, with her turning grey and becoming cold to the touch. Her parents reported that during home visits and at their local hospital, her symptoms were attributed to breastfeeding issues, weight loss, and jaundice.

Ms. Edmonds, who was experiencing significant pain from her own sores, described her mouth as "full of ulcers, my lips were swollen and it was painful to eat or drink." She continued to provide Maggie with expressed milk, as breastfeeding had become too painful, having been advised that it would help her daughter be less lethargic.

Having since researched the virus, Ms. Edmonds now suspects it may have been accidentally transferred from her mouth to her nipple. This, she believes, would explain the sores and the extreme pain she felt in that area, and how Maggie subsequently contracted the virus through contact during feeding. The virus is known to spread through direct contact with sores or infected saliva, not through breast milk itself.

By the time Maggie was admitted to the pediatric intensive care unit at Birmingham Children's Hospital, the virus had spread throughout her body, leading to multiple organ failure. She suffered a cardiac arrest the night before she passed away on February 11. Her parents were able to hold her as she died. Blood tests later confirmed the presence of HSV-1.

Ms. Edmonds was informed on the day of Maggie's death that her own sores had likely been a primary HSV infection, her first encounter with the virus when it is most contagious. She has not received a formal diagnosis for her own condition. "I don't even know how I contracted it, as no one around me had cold sores at the time," she said. "That's what's so dangerous about it. It can be anywhere."

According to the World Health Organization, approximately two-thirds of people under 50 carry HSV-1. While it typically causes mild symptoms like cold sores in adults, newborns have very limited defenses against it. Neonatal herpes affects about six in every 100,000 babies in the UK and Ireland, with nearly a quarter of infected infants dying, a figure that rises to two-thirds for those with the disseminated form of the disease.

A review of 35 infant deaths in England linked to HSV by the National Child Mortality Database last year recommended that parents be informed about the risks of cold sores during pregnancy.

Ms. Edmonds and her partner, Ben Brookes, 27, are now supporting Infection Prevention Week, a campaign organized by the baby charity The Lullaby Trust. A survey conducted for the charity found that 57% of parents had a relative kiss their baby without asking, and 46% felt uncomfortable asking loved ones to wash their hands.

"Newborns have immature immune systems, so setting your boundaries when it comes to touching and kissing your baby is a must," Ms. Edmonds urged. "It could save your baby's life." Jenny Ward, chief executive of The Lullaby Trust, emphasized that protecting a baby from infection is a justifiable act and not a sign of being rude or overprotective.
