A fundraiser is being held in Sudbury, Ont., this weekend to help pay for a three-year-old's medical supplies.

Elyarra Joly has immune deficiency and a rare genetic disorder called Alagille syndrome that causes jaundice, bumps and a persistent itch.

Recently, she was also diagnosed with Perthes disease. It is a rare condition that affects the hip.

Her mom, Elizabeth Judd, said it can be hard to find a balance between protecting her child from germs, and letting her go out and live her life.

"We'll go and she'll have a runny nose or cough the next day," Judd said.

"So it's really hard to decide do I socialize my child or do I keep her inside all the time?"

Medical equipment for three-year-old Elyarra costs thousands of dollars

Joly had a liver transplant in August 2015 to relieve some of her symptoms, but she is still on a feeding tube and has to make frequent trips from her home in Chelmsford, Ont., to Toronto for doctor appointments.

"Anywhere we go, I always have to think about who's touched this. Who's around us," she said.

"If that cough was just allergies. If that sneeze was just allergies. Or is that going to put my baby into the hospital?"

Despite Joly's condition, she can start school at the Sudbury Children's Treatment Centre this fall.

The fundraiser for her medical bills, which Judd said can cost thousands of dollars, takes place this Sunday at the Lockerby Legion in Sudbury.
