It is that lingering cough that just won’t quit. We keep telling ourselves it is just a cold until the third week hits. We have all been there, watching our kids head off to school with less energy than usual. They aren’t quite sick enough to stay in bed, but they aren’t themselves either.
Recently, health officials have noted elevated activity of Mycoplasma pneumoniae—better known as “walking pneumonia”—in classrooms. It is catching many parents off guard. Honestly, it is exhausting to play detective with every sniffle. Today, we are exposing the 8 specific signs that your child’s lingering cough is actually a marathon for their health.
1. The Hacking, Dry Cough
The primary sign parents see isn’t a high fever. Instead, children develop a persistent, dry cough that often worsens at night. Unlike a standard cold that peaks within five days, walking pneumonia has a gradual onset. You might notice your child is a little tired for a full week before real symptoms settle in. By the time the cough turns rhythmic and deep, the infection has already taken hold in the lungs. Parents specifically report a dry hack that lasts longer than ten days.
2. A Low-Grade Fever
Walking pneumonia is famous for staying “under the radar.” While regular pneumonia often brings a high fever, this version typically stays around 101°F or below. This low-grade heat can keep coming back or simply never go away, making it easy to mistake for a minor bug. If your child has a temperature that won’t break for more than five days, it is a major clue that the body is fighting a bacterial invader like Mycoplasma.
3. Unexpected Fatigue and Malaise
The “walking” part of the name is often a curse for recovery. Because kids feel “okay enough” to stay active, they don’t get the bed rest they need. You might notice your child is unusually quiet or skipping their favorite after-school activities. This deep-seated fatigue, or malaise, is the hallmark of the illness. It keeps them at about 70 percent capacity for weeks on end.
4. Chest and Stomach Pain
Unlike a head cold, walking pneumonia settles deep in the respiratory system. Children often complain of chest pain or soreness, especially when they cough. Surprisingly, if the infection is in the lower part of the lungs, it can also cause stomach pain or an “upset tummy” feeling. If your child is holding their ribs or belly during a coughing fit, it is time to look closer at their lungs.
5. Afternoon Headaches and Sinus Pressure
Many parents report that their children’s symptoms seem to flare up later in the day. Afternoon headaches and sinus pressure are frequent complaints during the first week of infection. These aren’t just from “school stress”—they are signs of the bacteria affecting the upper respiratory tract before it moves deeper.
6. Shortness of Breath During Activity
Since walking pneumonia affects the air sacs in the lungs, it directly impacts how much oxygen your child can get during play. You might notice them getting winded more easily during gym class or soccer practice. If they are struggling to catch their breath after normal activities, the infection may be causing inflammation in the windpipe and lungs.
7. A Scratchy Sore Throat and Chills
Early on, the infection often mimics the flu. A scratchy, persistent sore throat is common, often accompanied by mild chills. While these symptoms might seem to fade, they usually give way to the more aggressive “pneumonia cough” that characterizes the second and third weeks of the illness.
8. Unexpected Skin Rashes
This is the sign that catches parents most off guard. Mycoplasma can cause symptoms outside of the lungs, including mild skin rashes. These rashes can look like small bumps or even red patches that come and go during the illness. If a lingering cough is paired with a new, unexplained rash, it is a strong indicator of a Mycoplasma infection.
Protecting the Whole Household
The best way to stop the cycle is to realize that “walking” doesn’t mean “well.” If your child has that signature ten-day cough, keep them home for rest. This prevents the infection from settling deeper and protects the rest of your family. Adults can catch this too, and it often hits parents harder than the kids. Have you noticed yourself feeling winded lately? It might not just be the stress of the work week.
Walking pneumonia remains a significant concern this school season. By recognizing these 8 signs, you can get ahead of the infection before it drains your family’s energy. Take a proactive look at your child’s energy levels tonight—it might be the most important check-up you do all season.
