At least two children’s hospitals in Texas have recently treated pediatric patients for a mysterious inflammatory syndrome that experts have said is likely related to the novel coronavirus.

Two hospitals in Houston — Texas Children’s and Children’s Memorial Hermann Hospital — have reported cases of the so-called Multisystem Inflammatory Syndrome in Children (MIS-C), an inflammatory condition that is similar to Kawasaki disease, which causes swelling in arteries throughout the body.

Fewer than 10 patients are being treated at Texas Children’s, the Houston Chronicle reported.

Meanwhile, a spokesperson for Children’s Memorial Hermann Hospital told the outlet that the hospital treated  “several” pediatric patients for MIS-C in recent weeks.

More cases of the Kawasaki disease-like inflammatory condition are likely to pop up in children around the country as the virus continues to spread, experts have warned, and the increasing number of cases even prompted the Centers for Disease Control and Prevention (CDC) to recently issue an advisory regarding MIS-C.

Jacqueline Szmuszkovicz, a pediatric cardiologist at Children’s Hospital Los Angeles, recently said that children who have a fever that lasts for four or more days should seek medical attention.
