Respiratory Infection Q & A

What is a respiratory infection?

A respiratory infection is an infection of one of the parts of your body that’s responsible for breathing, such as the lungs, throat, airways, and sinuses. Respiratory infections affect either the upper or lower respiratory system, or both at the same time. 

The upper respiratory system runs from your vocal chords up to your sinuses. Common infections of the upper respiratory system include the common cold, tonsillitis, and laryngitis. The lower respiratory system runs from the vocal cords down to your lungs. Common infections of the lower respiratory system include pneumonia and bronchitis.

What causes a respiratory infection?

Most respiratory infections are caused by coming into contact with someone else carrying a virus or pathogen, but other factors increase your risk of infection, including:


  • Smoking
  • Exposure to harmful chemical gases
  • Exposure to air pollutants
  • Age
  • Weakened immune system
  • Acid reflux


Sometimes the common cold can develop into a respiratory infection, such as bronchitis or pneumonia. If you have cold symptoms that aren’t improving over time, call Diligent Medical Care, PC, for an appointment.

What are the symptoms of respiratory infections?

The most common respiratory infection symptoms include:


  • Nasal congestion
  • Chest congestion
  • Cough
  • Runny nose
  • Sore throat
  • Fever
  • Fatigue
  • Body aches


Symptoms affect people in different ways. Some experience minor symptoms while others require immediate medical treatment for respiratory infections. Go to the emergency room or call 911 if you experience chest pain and tightness, difficulty breathing, or a fever over 103.

How are respiratory infections treated?

When you visit Diligent Medical Care, PC, for respiratory symptoms, your doctor checks your lungs for abnormal breathing sounds and discusses your symptoms with you. Sometimes your doctor requests an X-ray to look for fluid or inflammation in the lungs.

Swabs from your mouth, nose, or throat help determine the cause of your respiratory infection to determine the best course of treatment. For example, bronchitis is usually a viral infection and antibiotics can’t treat a viral infection.

Respiratory infections are often treated with rest, anti-inflammatories, cough medicine, or antivirals. Inhalers may be prescribed if you have any difficulty breathing to open your airways.
