Boston Children's Hospital says they're seeing a "surge" of kids with a respiratory illness.
Dr. Michael Agus, the head of the Intensive Care Unit, says it's "very likely" the respiratory illness is Enterovirus D-68.
So far they've seen more than 150 children over the past week with respiratory problems.
About a dozen kids are so sick, they've been admitted to the critical care unit with problems breathing.
"Breathing hard, breathing fast, with wheezing," are tell-tale signs said Dr. Agus.
"We've been watching other cities track Enterovirus D-68 go through other cities in the country, and we've been expecting it to arrive here within these few weeks," added Dr. Agus.
Samples which have tested positive at the state level, have now been sent for ultimate confirmation at the Centers for Disease Control in Atlanta.

At Children's, Dr. Agus says in the most extreme cases, three children had to be put on a ventilator to help them breathe, but they're expected to make a full recovery.
He urges parents to watch their kids for symptoms that may call for extra attention.
"If the child is breathing very hard, gasping, if the parents are able to look at the breathing muscles above the clavicle or in between the ribs, and if the muscles are working extra hard, that's a patient that should be brought to the Emergency Department," said Dr. Agus.
He also says taking common sense measures like coughing or sneezing into your elbow, maintains good hand hygiene and staying home if your sick.
In Connecticut, a six-year-old girl has been confirmed to have the virus. She has since recovered.
