How Do You Get Pneumonia
You may get pneumonia:
- After you breathe infected air particles into your lungs.
- After you breathe certain bacteria from your nose and throat into your lungs.
- During or after a viral upper respiratory infection, such as a cold or influenza .
- As a complication of a viral illness, such as measles or chickenpox.
- If you breathe large amounts of food, gastric juices from the stomach, or vomit into the lungs . This can happen when you have had a medical condition that affects your ability to swallow, such as a seizure or a stroke.
A healthy personâs nose and throat often contain bacteria or viruses that cause pneumonia. Pneumonia can develop when these organisms spread to your lungs while your lungs are more likely to be infected. Examples of times when this can happen are during or soon after a cold or if you have a long-term illness, such as chronic obstructive pulmonary disease .
You can get pneumonia in your daily life, such as at school or work or when you are in a hospital or nursing home . Treatment may differ in healthcare-associated pneumonia, because bacteria causing the infection in hospitals may be different from those causing it in the community. This topic focuses on community-associated pneumonia.

- Stay away from people who have colds, the flu, or other respiratory tract infections.
- If you haven’t had measles or chickenpox or if you didn’t get vaccines against these diseases, avoid people who have them.
What Causes Chest Infections
Most bronchitis cases are caused by viruses. Most pneumonia cases are due to bacteria.
These infections are usually spread when an infected person coughs or sneezes. This launches tiny droplets of fluid containing the virus or bacteria into the air. These droplets can then be breathed in by others.
The infections can also be spread to others. This happens if you cough or sneeze onto your hand, an object or a surface, and someone else shakes your hand or touches those surfaces before touching their mouth or nose.
Certain groups of people have a higher risk of developing serious chest infections, such as:
- babies and very young children
- children with developmental problems
- people who are very overweight
- elderly people
- pregnant women
- people who smoke
- people with long-term health conditions, such as asthma, heart disease, diabetes, kidney disease, cystic fibrosis or chronic obstructive pulmonary disease
- people with a weakened immune system this could be due to a recent illness, a transplant, high-dose steroids, chemotherapy or a health condition, such as an undiagnosed HIV infection

Causes Of Walking Pneumonia
Walking pneumonia can be caused by viruses or bacteria. According to the American Lung Association, most cases are caused by M. pneumoniae, a common type of bacteria that usually affects children and adults under the age of 40. M. pneumoniae infections tend to peak in summer and early fall but can happen throughout the year.
Chlamydophila pneumoniae can also cause walking pneumonia. Infections from this type of bacteria are common in all four seasons. It often spreads in crowded environments, like college dorms and long-term care facilities.
Adults and children can also contract walking pneumonia from viruses. Respiratory syncytial virus is a frequent cause of walking pneumonia in young kids, while adults tend to get the viral form of the disease from the influenza virus.

This type of walking pneumonia is caused by Chlamydia pneumoniae bacteria. While it can cause a serious infection, most people experience only mild illness or no symptoms whatsoever. Its common among school-age children and young adults.
Legionnaires disease is one of the most serious types of walking pneumonia, as it can lead to both respiratory failure and death. Its caused by Legionella, a type of bacteria found in freshwater that can contaminate water systems in buildings. People can get this disease if they inhale airborne droplets of water that contain the bacteria.
Walking pneumonia symptoms are typically mild and look like the common cold. People may start noticing signs of walking pneumonia between 1 and 4 weeks of being exposed to the pathogen that caused the disease.
