Can You Catch Pneumonia From Someone Else?

Table of Contents

Pneumonia is an infection in one or both lungs. Its causes are viruses, bacteria, or fungi. The infection causes inflammation in the lungs’ air sacs, called alveoli. The alveoli fill with fluid or pus, making breathing difficult.

Both bacterial and viral pneumonia are contagious. This means that they can spread from person to person by inhaling airborne droplets from coughing or sneezing. You also get pneumonia if you touch surfaces or objects that contain bacteria and viruses that cause pneumonia.

Droplets in the respiratory air transmit the agent of pneumonia after sneezing or coughing and enter the body through the nose or mouth.

It is transmitted through contact with contaminated surfaces. In this disease, the lungs become inflamed, and the small air sacs, or alveoli, fill with fluid, making breathing difficult. Is the world

 

 

In this article from the health and beauty doctor, we will examine how each type of pneumonia spreads.

Types of pneumonia and its classification

Pneumonia can be classified based on the place of infection or the way it is contracted. Pneumonia is divided into two categories: community-acquired (CAP) and hospital-acquired (HAP).

  • Community-acquired pneumonia (CAP)

People get pneumonia in the community, not in the hospital. The bacteria and viruses that cause community-acquired pneumonia are different from those that cause hospital-acquired pneumonia.

 

  • Acquired pneumonia from Hospital (HEP)

Pneumonia that develops 48 hours after hospitalization is called hap. Ventilator-associated pneumonia is a type of hospital-acquired pneumonia that occurs 48 to 72 hours after intubation.

Ventilator-associated pneumonia accounts for approximately 80% of HAP cases, making it the most common form of infection in the ICU.

The most common microorganisms known to cause VAP are Pseudomonas aeruginosa, Staphylococcus aureus, and Enterobacteriaceae.

On the other hand, Candida and Enterococcus species may also cause VEP.

  • Pneumonia caused by aspiration in the respiratory tract

The cough reflex stops entering anything other than air into the respiratory tract. If sedatives and muscle relaxants disturb or destroy this natural reflex, the respiratory tract remains defenceless and causes pneumonia.

How contagious is pneumonia?

Pneumonia is contagious, like the flu or cold when infectious germs cause it. However, pneumonia is not contagious when caused by some type of poisoning, such as inhaling chemical fumes.

Pneumonia may be contagious for 2-14 days. Pneumonia may be contagious for 2-14 days. Medicines prescribed for pneumonia usually aim to limit the spread of the disease. A person with bacterial pneumonia is no longer contagious within two days of taking antibiotics.

Ways you can get pneumonia like Bacteria and viruses that live in your nose, sinuses, or mouth can spread to your lungs. You may breathe a small quantity of these germs directly into your lungs. You inhale food, liquids, vomit, or fluids from your mouth into your lungs (aspiration pneumonia).

There are many viruses that can lead to pneumonia, and viruses are easily spread from person to person. For example, the flu virus can remain on surfaces, making it even more contagious. Bacterial pneumonia can spread from person to person.

Which type of pneumonia is contagious?

Depending on the type of organism that causes it, it can spread to others

  • Communicable types of pneumonia

    1. Bacterial pneumonia

Bacterial pneumonia can be treated with antibiotics. The pneumonia is no longer contagious once the fever subsides or one to two days after the antibiotic is started.

Types of bacterial pneumonia that may be contagious include:

      • Streptococcus pneumoniae ( common cause of pneumonia)
      • Methicillin-resistant Staphylococcus aureus MRSA pneumonia
      • Chlamydial pneumonia
    1. Viral pneumonia

Viral pneumonia can also be contagious. Influenza virus, respiratory syncytial virus, RSV, and rhinoviruses (the cause of the common cold) can also cause pneumonia. Viral pneumonia is contagious until you feel better and a few days after the fever is over.

  • Non-communicable types of pneumonia

You may develop pneumonia that is not contagious. Pneumonia caused by chemicals or other toxins caused by noninfectious agents is not contagious.

    • Fungal pneumonia

Fungal infection usually occurs in people with weak immune systems or chronic diseases.

Fungi that lead to this type of pneumonia are usually found in soil, including Pneumocystis girosi, Cryptococcal species, and Histoplasmosis species.

In general, fungal pneumonia is not contagious because the cause of it is the inhalation of environmental fungi, and it is not spread from person to person.

    • Pneumonia due to aspiration into the respiratory tract

Aspiration pneumonia is also not contagious because it is caused by food or liquid entering the lungs.

This type of pneumonia may occur in people who have had a stroke or have other neurological diseases

How is pneumonia spread?

Pneumonia is contagious when pathogens (usually viruses or bacteria ) are expelled by an infected person by coughing up infected droplets. 

These expelled droplets contain bacteria or viruses that cause pneumonia. These droplets infect another person’s mouth or respiratory tract and eventually infect their lungs.

The approximate time of transmission of pneumonia varies with the type of infectious agent and may vary from one to two days to a week. 

In addition, some types of pneumonia are more contagious than others. For example, mycobacterium and mycoplasma organisms are highly contagious, but other types, including pneumococcal pneumonia, require favourable conditions to spread to another person and are weakly contagious.

 

How long is pneumonia contagious?

In general, most bacterial pneumonia are much less contagious after antibiotics are administered for about 24-48 hours. 

However, this period may differ for some organisms, such as those that cause tuberculosis. For tuberculosis, it takes two weeks or more of antibiotics to make the person no longer contagious. 

In the case of viral pneumonia, the person will decline after the onset of symptoms, especially fever. 

This may occur about a day or two after a person is fever-free, but someone with some viral pneumonia may shed the infectious virus for a week or more. It is common to have an occasional cough for a while (days to weeks), even after a person is not contagious.

What is the prevention of pneumonia?

To help prevent this disease, you can do the following.

Vaccinate. In order to prevent some types of pneumonia and influenza, Vaccines are available. Of course, before receiving these vaccines, be sure to consult your doctor;

Take good care of your health. To protect yourself from respiratory infections that sometimes cause pneumonia, wash your hands regularly or use alcohol-based hand sanitisers;

Do not smoke. Smoking damages your lungs’ natural defence system against respiratory infections;

strengthen your immune system. Get enough sleep, eat healthy meals and exercise regularly.

Home remedies for pneumonia

Although home remedies may not cure pneumonia, there are steps you can take to decrease symptoms. 

Cough is one of the most common symptoms of this disease. One of the natural ways to relieve a cough is to gargle with salt water or drink peppermint tea. 

Also, cool compresses can reduce fever. Drinking warm water or eating a bowl of warm soup can also help relieve the chills caused by pneumonia.

If you have the question of what to eat for a lung infection, plenty of fluids will be the answer to this question. 

You can help your recovery and prevent relapse by resting well and drinking plenty of fluids. Although home remedies can help reduce symptoms, it is important to stick to the treatment plan prescribed by your doctor. 

It is necessary to take any prescribed medication as directed by your doctor until complete recovery.

Conclusion

As discussed in detail in this article, pneumonia is contagious in some cases and not contagious in some cases. In cases where it spreads, you may not notice pneumonia for a long time and mistake it for a cold.

In any case, the best way is to know the symptoms of pneumonia and how it spreads and take action to prevent it at the best possible time.
