Pneumonia infects thousands and thousands of individuals yearly. Circumstances of this extremely contagious lung an infection surged throughout all age teams in 2024, however younger kids had been hit notably laborious. An infection charges in kids 2 to 4 years outdated elevated from 1.0% to 7.2% between March and October of final yr, in line with the Facilities for Illness Management and Prevention (CDC).
Pneumonia can begin from greater than 300 totally different sorts of micro organism, viruses, and fungi, however a selected micro organism referred to as Mycoplasma pneumoniae was answerable for a lot of final yr’s surge. This micro organism has not traditionally been a number one reason for pneumonia in younger kids, the rise of which could possibly be on account of a drop in vaccination charges and less-exposed immune methods for the reason that COVID-19 pandemic.
Jeffrey Griffiths, a professor within the Division of Public Well being and Neighborhood Medication at Tufts College Faculty of Medication, explains the totally different sorts of pneumonia, easy methods to deal with it, and, most significantly, easy methods to stop an infection within the first place.
The numerous causes of pneumonia
M. pneumoniae is likely one of the most typical bacterial causes of what’s also known as “walking pneumonia,” a milder type of the illness. Strolling pneumonia signs are sometimes not extreme sufficient to maintain folks laid up at house, so they could be strolling round with the illness, therefore the identify.
The commonest reason for extra extreme instances of pneumonia around the globe is a micro organism referred to as Streptococcus pneumoniae, a kind of strep. Probably the most susceptible populations embody the very younger and really outdated, anybody who’s malnourished, and those that are immunocompromised.
There are a number of different much less frequent bacterial causes of pneumonia. Bacterial pneumonia typically develops after a milder viral lung an infection, resembling these attributable to frequent viruses we’re all too accustomed to.
“We have had an immense surge of influenza, respiratory syncytial virus (RSV), and COVID-19 going on in the U.S.,” Griffiths says. “Each of these has its own season. COVID-19 peaked in the Boston area this winter in January 2025, while influenza really ramped up in December 2024 and is still at very high levels nationally.”
Masks up and wash your palms
Pneumonia could be very contagious. Each cough presents a possibility for somebody close by to breathe it in or contact an contaminated floor. With out taking precautions, we are able to transport pneumonia into our personal lungs.
Griffiths recommends sporting a masks, not less than in crowded indoor areas resembling airports, and washing our palms extra typically and extra completely. These two measures can stop spreading or getting contaminated with the organisms that trigger pneumonia. He additionally emphasizes that these behaviors are extra vital through the chilly winter months once we spend extra time inside.
Discover the indicators: Inexperienced and yellow phlegm
As a result of pneumonia causes irritation and fluid buildup within the lungs, it compromises our capability to get oxygen from the air and thru our bloodstream to assist the remainder of our physique’s capabilities.
“It’s low oxygen that gets you in trouble,” Griffiths says.
Not like a head chilly, pneumonia comes with loads of coughing. Adults with pneumonia often have a fever, cough up inexperienced and yellow phlegm, and turn into winded a lot simpler, even from easy actions like strolling or going up stairs.
Coughing excessively can result in its personal points. Once we breathe, the liner on the skin of our lungs rubs in opposition to the liner on the within of our ribs. Coughing with already infected lungs additional irritates that motion and could be painful and even pressure an intercostal muscle.
However pneumonia presents otherwise in kids. Griffiths says that whereas grownup signs are extra clearly lung-related, kids might solely present quick respiratory charges with different signs like abdomen aches, a refusal to drink fluids, or vomiting. Younger kids additionally are inclined to swallow phlegm, in contrast to adults who spit it out.
If prevention measures fail and signs come up, it is vital to hunt medical therapy as early as potential.
Antibiotics, vaccines, and at-home oxygen screens
The therapy choices for pneumonia differ based mostly on its supply. Bacterial pneumonia can typically be handled with antibiotics, however overuse of those medicines can result in antibiotic resistance. The earlier we get antibiotics, the earlier we really feel higher and the much less seemingly we’re to have additional issues.
The commonest form of bacterial pneumonia (S. pneumoniae) additionally has a set of vaccines which prepare the immune system to combat them off. The CDC recommends the pneumonia vaccine for kids beneath 5 and adults aged 50 or older. In accordance with the CDC, solely 24.9% of adults had ever acquired a pneumococcal vaccination as of 2023.
“When you get a vaccine, you’re not only protecting yourself, but you may also be protecting your immunocompromised relative or your grandparents,” Griffiths says. “There are secondary benefits to the people around. It’s a social good.”
Pneumonia attributable to viruses, then again, has far fewer therapy choices than these attributable to micro organism. There are some remedies that may assist influenza if began within the first 48 hours of signs and a few oral remedies can be found for COVID-19.
Apart from getting vaccinated for frequent viruses just like the flu, RSV, or COVID-19, we’re left with symptom administration. Griffiths recommends staying hydrated and taking Acetaminophen or ibuprofen for ache administration whereas retaining a detailed eye on oxygen ranges.
“There are little portable finger monitors, called pulse oximeters, that monitor your oxygen,” Griffiths says. “You can buy them now for roughly $20 online. They are quite helpful in terms of assessing your oxygen levels at home.”
For self-monitoring, oxygen ranges ought to be 94% or increased. People who smoke or others with compromised lungs may need barely decrease oxygen ranges, round 92%.
“You never know. If you’ve got a thermometer in the house, you might as well have an oxygen monitor,” Griffiths says. “These are common infections.”
