How You Catch Pneumonia

Pneumonia

While anyone can catch pneumonia, some people are more likely to come down with illness when coming into contact with the germs. Like many other illnesses, pneumonia is caught through contact with the bacteria or virus that creates pneumonia.

Coughing and sneezing are the most common ways these germs spread.

Its also possible to catch the illness by touching something like a counter or door handle, sharing cups and utensils, and touching your face without washing your hands first.

Spreading Pneumonia To Others

If your pneumonia is caused by a virus or bacteria, you may spread the infection to other people while you are contagious. How long you are contagious depends on what is causing the pneumonia and whether you get treatment. You may be contagious for several days to a week.

If you get antibiotics, you usually cannot spread the infection to others after a day of treatment.

What Is Aspiration Pneumonia

Aspiration pneumonia is pneumonia that is caused by something other than air being inhaled into your respiratory tract. These non-air substances can be food, liquid, saliva, stomach contents, toxins or even a small foreign object.

Theres also a condition called aspiration pneumonitis which is caused by the same type of thing happening but there is only inflammation and irritation, not infection. Its difficult to tell the two conditions apart.

Other names for aspiration pneumonia include anaerobic pneumonia, necrotizing pneumonia and aspiration of vomitus.

What Increases Your Risk

How do you Get a Pneumonia?

You are more likely to get pneumonia if you:

  • Smoke. Cigarette smoking is a strong risk factor for pneumonia in healthy young people.
  • Have another medical condition, especially lung diseases such as chronic obstructive pulmonary disease or asthma.
  • Are younger than 1 year of age or older than 65.
  • Have an impaired immune system.
  • Take medicine called a proton pump inhibitor that reduces the amount of stomach acid.footnote 3, footnote 4
  • Drink excessive amounts of alcohol.
  • Recently had a cold or the flu.

You are more likely to have complications of pneumonia and need to go to the hospital if you:

  • Are older than 65.
  • Have some other illness , or have gone to the hospital for a medical problem within the last 3 months.
  • Have had your spleen removed or do not have a working spleen .
  • Have an alcohol use problem.
  • Have a weak immune system.
  • Reside in a place where people live close together, such as a university dorm or nursing home.

Cover Your Mouth And Nose

While the preferred method for covering your mouth when you cough or sneeze is into a tissue, not everyone can get to tissues in time when the urge to cough or sneeze hits. If you have the urge to cough or sneezeand a tissue isnt availablethe next best thing is to cover your mouth or nose with the inside of your elbow.

Coughing or sneezing into your elbow will decrease the chances of your leaving traces of your infection on door handles, faucets, or anything else you touch.

How Do You Diagnose Pneumonia

  • Symptoms – a doctor will suspect pneumonia from asking about your symptoms and how you are feeling. They may also ask about your medical history and that of your family. They will be interested in whether you smoke, how much and for how long. The examination may include checking your temperature. Sometimes your doctor will check how much oxygen is circulating around your body. This is done with a small device that sits on the end of your finger. The doctor will listen to your chest, so they may want you to lift or take off your top. If you want a chaperone during the examination, the doctor will arrange one. If you have asthma, they may ask you to check your peak flow measurement. They will listen to your chest with a stethoscope. Tapping your chest over the infected lung is also sometimes performed. This is called percussion. An area of infected lung may sound dull.
  • X-ray – a chest X-ray may be required to confirm the diagnosis and to see how serious the infection is.
  • Other tests – these tests are usually carried out if you need to be admitted to hospital. They include sending a sample of phlegm for analysis and blood cultures to check if the infection has spread to your blood.

What To Think About

What can I do to prevent getting pneumonia?

In most cases pneumonia is a short-term, treatable illness. But frequent bouts of pneumonia can be a serious complication of a long-term illness, such as chronic obstructive pulmonary disease . If you have a severe long-term illness, it may be hard to treat your pneumonia, or you may choose not to treat it. You and your doctor should discuss this. This discussion may include information about how to create an advance care plan.

There are a number of steps you can take to help prevent getting pneumonia.

  • Stop smoking. You’re more likely to get pneumonia if you smoke.
  • Avoid people who have infections that sometimes lead to 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.

    The Main Causes Of Pneumonia:

    • Exposure to a germ
    • Weakened immune system

    Some of the germs that cause pneumonia are easily spread from one person to another. They are carried in the nose and throat of an infected person. When an infected person coughs or sneezes, they spray drops of infected saliva into the air around them. A person who breathes in that air can get pneumonia.

    There are many things you can do to lower your risk of getting pneumonia. Not smoking is an important way to help prevent pneumonia. People who smoke, and children whose parents smoke, are at a higher risk of getting pneumonia.

    Pneumococcal vaccinations help protect you against invasive pneumococcal infections such as pneumonia, bacteremia and meningitis .

    Ask your health-care provider about getting the pneumococcal vaccination. For details on when the pneumococcal vaccinations are required, starting at two months of age, see Ontarios Routine Immunization Schedule. Some adults may need it every five years. Prevention of pneumonia through immunization is even more important now since some infections have become more resistant to antibiotics.

    Things You Should Know About Pneumonia

    Pneumonia is an infection that causes the air sacs in the lungs to fill up with fluid or pus, which makes it harder to breathe. The most common symptoms are cough that may be dry or produce phlegm, fever, chills and fatigue. Other symptoms may include nausea, vomiting, diarrhea, and pain in the chest. and shortness of breath. Signs that indicate a more severe infection are shortness of breath, confusion, decreased urination and lightheadedness. In the U.S., pneumonia accounts for 1.3 visits to the Emergency Department, and 50,000 deaths annually.

    With the COVID-19 pandemic continuing to affect people around the world, pneumonia has become an even larger health concern. Some people infected with the COVID-19 have no symptoms, while others may experience fever, body ache, dry cough, fatigue, chills, headache, sore throat, loss of appetite, and loss of smell.

    The more severe symptoms of COV-19, such as high fever, severe cough, and shortness of breath, usually mean significant lung involvement. The lungs can be damaged by overwhelming COVID-19 viral infection, severe inflammation, and/or a secondary bacterial pneumonia. COVID-19 can lead to long lasting lung damage.

    Lab Tests For Pneumonia

    The need for more tests often depends on how severe your symptoms are, your age, and your overall health. In general, the sicker you are, the more tests you may need. This is especially true for older adults and infants. One example of a test you may have is the arterial blood gas test.

    Mucus test

    If you are very ill, have severe shortness of breath, or have a condition that increases your risk , your doctor may test your mucus. Tests include a Gram stain and a sputum culture.

    Rapid urine test

    This test can identify some bacteria that cause pneumonia. This can help guide treatment for pneumonia.

    HIV test

    In people who have impaired immune systems, pneumonia may be caused by other organisms, including some forms of fungi, such as Pneumocystis jiroveci . This fungus often causes pneumonia in people who have AIDS. Some doctors may suggest an HIV test if they think that Pneumocystis jiroveci is causing the pneumonia.

    Other lung tests

    If you have severe pneumonia, you may need other tests, including tests to check for complications and to find out how well your immune system is working.

    Can You Catch Pneumonia More Than Once

    Yes. Pneumonia is caused by many different microbes, and so getting it once does not protect you from getting it again. If you get pneumonia more than once you may need to have more investigations to understand why this has happened. It could be due to a problem in your chest or your immune system, and you may be referred to a specialist.

    Pneumonia Symptoms And Causes

    Thinkstock

    There are more than 30 different causes of pneumonia, including bacteria, viruses, airborne irritants, and fungi. When these germs enter the lungs, they can overpower the immune system and invade nearby lung tissues, which are very delicate.

    Once infected, the air sacs in the lungs become inflamed and fill up with fluid and pus, which causes coughing, fever, chills, and breathing problems.

    Questions About Your Symptoms

    How Long does Pneumonia take to Heal? and Essential ...

    Bacterial pneumonia, which is the most common form, tends to be more serious than other types of pneumonia, with symptoms that require medical care. The symptoms of bacterial pneumonia can develop gradually or suddenly. Fever may rise as high as a dangerous 105 degrees F, with profuse sweating and rapidly increased breathing and pulse rate. Lips and nailbeds may have a bluish color due to lack of oxygen in the blood. A patient’s mental state may be confused or delirious.

    The symptoms of viral pneumonia usually develop over a period of several days. Early symptoms are similar to influenza symptoms: fever, a dry cough, headache, muscle pain, and weakness. Within a day or two, the symptoms typically get worse, with increasing cough, shortness of breath and muscle pain. There may be a high fever and there may be blueness of the lips.

    Symptoms may vary in certain populations. Newborns and infants may not show any signs of the infection. Or, they may vomit, have a fever and cough, or appear restless, sick, or tired and without energy. Older adults and people who have serious illnesses or weak immune systems may have fewer and milder symptoms. They may even have a lower than normal temperature. Older adults who have pneumonia sometimes have sudden changes in mental awareness. For individuals that already have a chronic lung disease, those symptoms may worsen.
