A quick search for “white lung pneumonia” or “white lung syndrome” can send you down a rabbit hole of alarming reports describing a new respiratory disease affecting children.

Indeed, cases of pediatric pneumonia are on the rise in China, prompting theWorld Health Organizationto officially request information on the cases on Nov. 22. And stateside, Ohio’s Warren County issuedan official alerton Nov. 29 after an “extremely high number of pediatric pneumonia cases” — 142 — were reported.

But it’s not an emerging pandemic.

Warren County pointed out this fact in its alert, saying, “We do not think this is a novel/new respiratory disease but rather a large uptick in the number of pneumonia cases normally seen at one time.”

According tothe CDC, “Mycoplasma pneumoniae bacteria commonly cause mild infections of the respiratory system.”

“We know that every three to seven years, mycoplasma does surge in a natural cycle,”Ian Michelow, MD, professor of pediatrics at the University of Connecticut and head of the pediatric infectious diseases division at Connecticut Children’s, toldHealth.

The CDC is looking into the recent rise in cases — although most doctors seem unconcerned.

“I think COVID heightened all of our anxiety levels,”  Dr. Molly O’Shea, a pediatrician at Birmingham Pediatrics and Wellness Center toldWXYZ-Detroit,

“Really, it’s just a name for plain old, boring… pneumonia,” she said.

And as Dr. Schneider tells PEOPLE, “it’s nothing new and we have treatments for it. It’s something to be aware of, because we look at trends of when infections are occurring so we can better predict what is causing an infection so we can treat it appropriately. But it’s nothing that I would start turning any alarm bells ringing,”

The name “white lung pneumonia” comes from the lungs appearing white or having white spots on a chest X-ray.

Symptoms are that of a “chest cold,”the CDC explains, and include a sore throat, fatigue, and a worsening cough. Very young children (under the age of 5) may have gastrointestinal symptoms as well that include diarrhea and vomiting.

And as Dr. Schneider points out, “We generally refer to a mycoplasma pneumonia infection as walking pneumonia, meaning patients are often not that sick. They have a cough, maybe a little bit of fever and otherwise can go about their day.”

However, he points out, “they’re contagious just like any other patient who has any other infection in their lungs.”

”It’s really layers,”  Dr. Mandy K. Cohen, MD, MPH, the Director for theCDC,tells PEOPLE. “Washing your hands, wearing a mask, opening up that window [for ventilation]. You know, doing the things that we know can protect ourselves and each other.”
