The California initiative that offers the globe’s sole medical intervention for life-threatening infant botulism also provides a unique kind of solace to distressed families: whimsical birthday cards for their little ones’ first milestones.

Annually, the personnel at the state’s Infant Botulism Treatment and Prevention Program lovingly create and dispatch around 200 birthday cards to commemorate the recovery of youngsters stricken by this rare but serious ailment.

In the past few months, this effort has embraced numerous American infants impacted by a botulism outbreak linked to tainted ByHeart baby formula.

Amy Mazziotti from Burbank, California, received one of these heartfelt birthday greetings for her son, Hank, in September. This came after his 12-day hospitalization due to botulism contracted from ByHeart formula.

“The effort they put into sending these personalized, hand-crafted cards is truly remarkable,” Mazziotti expressed. “When you’re fraught with concern for your child, gestures like this can seem incredibly significant.”

Robin Hinks, a program assistant, oversees the artistic, logistical, and mailing aspects of these meaningful cards.

“I am a big fan of drawing animals with party hats,” said Hinks, who favors crayons and colored pencils. “Like, here’s a frog with some balloons and a little penguin.”

The program’s primary purpose is to help diagnose and treat the disease that occurs when babies ingest botulism spores that germinate in the intestine and produce a dangerous toxin that attacks the nervous system, causing paralysis. Death rates were once as high as 90%, but now are less than 1% with treatment.

The only treatment, known as BabyBIG, is an IV medication made from the pooled blood plasma of adults who have been immunized against botulism. California’s program is the sole source worldwide. After it was approved

Because the disease is so rare, with about 200 cases treated each year, the botulism center has become a source of information and connection for families facing the ordeal.

“Support of the babies and their families remains paramount to our program and our mission,” said Dr. Jessica Khouri, the program’s senior medical officer.

Heather Goody, of Gallipolis, Ohio, said she felt alone when her daughter, MaryEllen, contracted infant botulism in 2016. Nearly a decade later, Goody still runs a Facebook group, Infant Botulism Awareness, to connect the parents of sick babies. It now has more than 500 members.

She still recalls how touching it was to receive a card on MaryEllen’s first birthday.

“It brought all the feels, but most importantly the feeling of gratitude that she was thriving in all areas of life,” Goody said.

Maintaining that connection was a priority for the late Dr. Stephen Arnon, who with colleagues in 1976 identified the rare form of botulism that affects babies younger than 1 — and then spent the next 45 years figuring out how to treat it.

Arnon, who died in 2022, stayed in close touch with families of kids sickened by infant botulism, updating them as his scientific work progressed.

Today, nearly 1,500 families are part of the botulism program’s parent network, which includes children treated two decades ago. The group shares everything from preschool graduations to college acceptances and other milestones.

“Former patients have gone on to have families of their own and keep in touch with us,” Khouri said. “It really is an incredible part of the work we do.”
