Health experts are noticing an increase in children diagnosed with a rare inflammatory syndrome.

Pediatrician at South Texas Health System Dr. Ivelisse Barouhas says she's seen more cases of multisystem inflammatory syndrome in children (MIS-C), an immune response to COVID-19 in kids. 

Experts say the condition can cause inflammation in the heart, kidney, lungs, and other essential organs. 

Though MIS-C only affects a small percentage of kids, Barouhas says it's more common in children with underlying conditions. 

Doctors say the best way to protect kids from the condition is for those 12 and older to get vaccinated against COVID-19.
