Pneumonia is caused by quizlet? (2023)

What is pneumonia mainly caused by?

Viruses that infect your lungs and airways can cause pneumonia. The flu (influenza virus) and the common cold (rhinovirus) are the most common causes of viral pneumonia in adults. Respiratory syncytial virus (RSV) is the most common cause of viral pneumonia in young children.

Pneumonia is an infection of one or both of the lungs caused by bacteria, viruses, or fungi. It is a serious infection in which the air sacs fill with pus and other liquid. Lobar pneumonia affects one or more sections (lobes) of the lungs.

The most common cause of community-acquired pneumonia (CAP) is S. pneumoniae, followed by Klebsiella pneumoniae, Haemophilus influenzae, and Pseudomonas aeruginosa.

Streptococcus pneumoniae is the most common cause of bacterial pneumonia in children. Haemophilus influenzae type b (Hib) is the second most common cause of bacterial pneumonia. Respiratory syncytial virus is the most common viral cause of pneumonia.

The two most common causes of pneumonia are from viral pathogens or bacterial pathogens. Some types of bacterial pneumonia can be prevented with vaccines, such as the aggressive bacteria Strep. Pneumoniae, prevented with the pneumococcal vaccine.

It might surprise you to find out that neither cold weather nor wet hair can cause you to catch pneumonia. In fact, pneumonia in itself isn't contagious, so you can't really “catch” it at all.

What is pneumonia causes and treatment?

Pneumonia is a bacterial or viral infection of the lungs. Symptoms can include fever, chills, shortness of breath, coughing that produces phlegm, and chest pain. Pneumonia can usually be treated at home with antibiotics but some cases may require time in hospital and can result in death.

Catching pneumonia

The germs that can cause pneumonia are usually breathed in. People often have small amounts of germs in their nose and throat that can be passed on through: coughs and sneezes – these launch tiny droplets of fluid containing germs into the air, which someone else can breathe in.

Most viral pneumonias are not serious and last a shorter time than bacterial pneumonia. COVID-19 pneumonia can be severe, causing low levels of oxygen in the blood and lead to respiratory failure and in many cases a condition called acute respiratory distress syndrome (ARDS).

Fungal pneumonia and aspiration pneumonia are examples of pneumonias that aren't usually contagious. Fungal pneumonia is caused by inhaled fungi from your environment. It's not spread from person to person. The fungi that cause this type of pneumonia are usually found in soil.

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.

Once a person who has pneumonia starts on antibiotics, he or she only remains contagious for the next 24 to 48 hours. This can be longer for certain types of organisms, including those that cause the disease tuberculosis. In that case, someone can remain contagious for up to two weeks after starting on antibiotics.

Pneumonia is an infection of the lungs that can cause mild to severe illness in people of all ages. However, some people are at increased risk for getting pneumonia. Being a certain age, having certain medical conditions, and smoking can increase a person's risk for pneumonia.

It may take time to recover from pneumonia. Some people feel better and are able to return to their normal routines in 1 to 2 weeks. For others, it can take a month or longer. Most people continue to feel tired for about a month.

What is the best antibiotic to treat pneumonia?

The first-line treatment for pneumonia in adults is macrolide antibiotics, like azithromycin or erythromycin. In children, the first-line treatment for bacterial pneumonia is typically amoxicillin.

Don't try to run back to work and infect everyone else. Rest until you feel better. Whatever you do, don't smoke, it will only make your pneumonia worse. If your pneumonia is really severe or you have another serious health problem, your doctor may recommend that you get treated in the hospital.
