Resistant Ringworm Common in Some Elementary Schools

Treatment-resistant ringworm is common among urban elementary school children — at least according to a new report from U.S. researchers. They studied 10,514 children in kindergarten through Grade 5 at 44 schools across the bi-state Kansas City metropolitan area, and found that 6.6 percent of them were infected with the fungus (T. tonsurans) that causes ringworm, which can cause scaly, itchy scalps and hair loss. Here are the details from a HealthDay article:
Infection rates varied by age and race. More than 18 percent of black children in kindergarten and the first grade were infected. That rate dropped to 7 percent by fifth grade. Infection rates were 1.6 percent for Hispanic children and 1.1 percent for white children. The reasons for the higher rate among black children aren’t clear. The study is published in Pediatrics.
“The organism T. tonsurans has become the leading cause of scalp infection in the U.S., and we believe it is on the rise in inner city areas,” study author Susan Abdel-Rahman, a professor of pediatrics and pharmacy at Children’s Mercy Hospitals and Clinics, said in a news release.
“This study supports what I and many of my peers are seeing, children with scaly, itchy scalps and hair loss are prevalent in metropolitan areas. If not treated, ringworm can lead to permanent hair loss, which can damage a child’s self-image. There is also some evidence that it may worsen seemingly unrelated problems such as asthma and allergic rhinitis.”
The oral antifungal medicine used to treat ringworm does not completely eliminate the fungus in many children, which means they can spread the infection to others even after treatment.
T. tonsurans has learned how to stay on the host and avoid eradication. This can be very frustrating for children who keep getting re-infected and for their parents who are doing everything they can to prevent this,” Abdel-Rahman said.
“We have only recently started to appreciate just how many children carry this pathogen so we don’t yet know the best way to tackle this problem. However, I do advise parents to limit the sharing of items that come into contact with the scalp, such as hats, combs, brushes and pillows.
“Watch closely for signs of infection, such as flaking that looks like dandruff, white patchy scaling, itching, hair thinning or loss, and small pus-filled bumps, especially when your child has come in contact with another infected child. Make an appointment to see your doctor if you suspect that your child is infected and make sure to take the prescribed medicine as directed along with the application of a medicated shampoo two to three times a week.”
The Nemours Foundation has more information about ringworm and related infections.

    My son still has this after I treated it for two weeks it came back. when one child has it spread like wildfire. I took my son to a pediatric dermatologist specialist and they prescribed the shampoo the oral medicine and the liquid ointment for his scalp, I have to treat this for 3 months in order or it to go away. Now a days the doctor says the ringworm has become resistant to the medication.. It sucks but as a parent I have to do this. It started off as a tiny dot and grew into a circle the size of a fist. It’s very contagious, sometimes I wae up with it on my arms, neosporn works for temporary. I try to eep it most at all times it doesn’t hurt him just itches.. I have been on three doctor visit it seems to be going away but this is the first month so we shall see!!!
