Lake Forest Dance Academy officials are warning parents of a case of fifth disease discovered after a recent recital.
Sandy Ragsdale, director of the academy, which is run by the Lake Forest Parks and Recreation Department, said the sickness was discovered in a girl about 9 years old.
The Centers for Disease Control and Prevention's website describes fifth disease as "a mild rash illness" that is more common in children than adults. According to the website, symptoms include fever, runny nose, headache and after several days a red rash on the face known as "slapped cheek" rash.
The website says those infected usually get sick within four to 14 days, and about 20 percent of those with the fifth disease virus won't show any symptoms.
Ragsdale compared fifth disease to other childhood diseases such as chicken pox. She said the academy wanted to alert parents in the same way it would for a case of strep throat.
She said "hundreds" of kids and adults could potentially have come in contact during the recitals, which ran from May 16 to 18.
"That's why (the notification) was sent out to the recital at large," Ragsdale said. "She only dances with a small group, but we were all together at Lake Forest High School for our recitals. Everyone was in the same vicinity."
She said there haven't been other reports of children coming down with the virus.
The academy was notified on May 21 by the child's mother after a doctor's visit, she said.
Other symptoms include pain and swelling in the joints — more common in adult women than any other group — that usually lasts one to three weeks but goes away without long-term problems, according to the CDC. A second, potentially itchy rash may also form on the chest, back, butt, arms and legs.
The rash, according to the CDC, typically disappears in seven to 10 days, but it can last several weeks.
The disease is generally spread through mucus, saliva or blood, according to the CDC.
