Can You Have Pneumonia Without a Fever?

Pneumonia is a respiratory infection where the tiny air sacs in your lungs become inflamed and filled with fluid. It can range in severity from mild to life-threatening.

Although fever is a common symptom of pneumonia, in some cases you can have pneumonia without a fever.

Read on to learn more about this topic, the different types and causes of pneumonia, and symptoms to look for.

Symptoms of pneumonia
Common symptoms of pneumonia include:

cough that can produce mucus
chest pain, which may get worse when coughing or breathing deeply
rapid breathing or shortness of breath
fever
sweating or chills
feeling tired or fatigued
loss of appetite
nausea or vomiting
Pneumonia and fever
Pneumonia symptoms, such as fever, may be absent or less severe in some populations, including:

newborns
infants
older adults
In these situations, there may be other warning signs to look out for.

Older adults or people with a compromised immune system may actually have a lower body temperature if they have pneumonia. Additionally, older adults with pneumonia may also have changes in mental state, such as confusion.

Newborns and infants may or may not have a fever, but can experience rapid breathing, nasal flaring, and grunting. Signs of a very severe infection may also include not eating, low body temperature, and convulsions.

What causes pneumonia?
Pneumonia can also be classified by the type of germ that’s causing it. These can include things like bacteria, viruses, and fungi.

Bacterial pneumonia
Bacterial pneumonia can be divided into typical and atypical types. Common typical bacteria include Streptococcus pneumoniae and Haemophilus influenzae.

Atypical bacteria can include:

Mycoplasma pneumoniae
Legionella pneumophila
Chlamydia pneumoniae
Many types of bacterial pneumonia involve symptoms like high fever, sweating, and quick breathing.

People with atypical (walking) pneumonia may experience milder symptoms, such as low-grade fever, headache, and dry cough.

While fever is a common symptom of pneumonia, it’s possible to have pneumonia without a fever. This can occur in specific groups, such as young children, older adults, and people with a weakened immune system.

Pneumonia can be caused by a variety of germs, some of which are contagious. The treatment and recovery time can be dependent on what’s causing your illness as well as on your overall health.

It’s important that pneumonia is treated promptly to prevent complications. If you suspect you have pneumonia, make an appointment with your doctor to discuss your concerns and receive a diagnosis. Source: HealthLine
