But what exactly is walking pneumonia?

“Walking pneumonia is a layman’s term for a type of pneumonia that, in medical terms, we call atypical pneumonia. That just means that they [the patients] don’t follow the sort of normal course of fever, cough and acute worsening,” Dr. Matthew Isaac Harris, a pediatric emergency medicine physician and the medical director for Critical Care Transport at the New York-based Northwell Health, tells PEOPLE.

“They look clinically better than the average case,” he explains, adding that these less severe symptoms can lead to a delayed diagnosis.

“They have maybe a week to two weeks of worsening cough. Sometimes it’s some fever,” Dr. Harris says. “They don’t have that classic three-to-four days of high fever, productive cough that you might see in the more classic pneumonia.”

But while cases are rising, ”this isn’t a unique year,” the doctor adds. “We do have these spurts of mycoplasma pneumonia every couple of years."

As for why it’s spreading among children, he explains, “They’re constantly coughing in small classrooms or in nursery school or in playgroups. The things that put kids at higher risk are just their exposure to other kids who are constantly coughing in their vicinity.”

“The spike this year happens every couple of years,” he explained. “It is highly infectious.”

The good news, Dr. Harris tells PEOPLE, is that it’s “very, very treatable” with antibiotics — generally azithromycin, which he explained is “more colloquially known as the Z-pack.”

“It’s once a day for five days, so this is not the time you’re gonna have to struggle with your kid three times a day trying to get in a large volume of antibiotics,” he tells PEOPLE.

And no matter how quickly your child recovers, “it’s critically important to complete the whole course.”

However, Dr. Harris also advises parents to avoid over-the-counter cough medications.

Although the CDC issued an alert, Dr. Harris says “we’re in the stage of ‘Be mindful’.”

“Look out for those signs of respiratory distress, which is really something again for younger children under the age of 2. Older kids will tell you they’re not feeling well.”

He advised parents to watch for symptoms including “breathing faster, not drinking as much, maybe not peeing as much because they’re not drinking.”

“We do not want parents to run to the pediatrician every time their child’s coughing,” the doctor says. “It really is just that cough that’s slowly worsening and having low-grade fevers after a week to 10 days, not getting better, That’s really the time to go see your pediatrician.”
