Study Notes
Infection of Upper Respiratory Tract
- The speaker is currently experiencing an infection of the upper respiratory tract (URT)
- The speaker has:
- Sore throat
- Stuffy and runny nose
- Fever (101.8 degrees Fahrenheit or 38.8 degrees Celsius)
Infection Explained
- An infection is when a pathogen enters the body's tissues and cells causing a reaction
- The most common pathogens for URT infections are:
- Bacteria: Usually a chain of bacteria
- Viruses: The most common type being rhinoviruses
Upper Respiratory Tract Anatomy
- URT is a general term with several components:
- Nasal cavity: If infected, it is called rhinitis
- Pharynx: This is the back of the throat where the uvula hangs, a sore throat is called pharyngitis
- Epiglottis: A flap that covers the airway when swallowing, infection here is epiglottitis
- Larynx: Houses the vocal cords, an infection here is laryngitis
- Trachea (windpipe): While typically not part of the URT in discussions, infections can occur here (tracheitis)
Symptoms of URT Infections
- Runny or Stuffy Nose: An overreaction to illness, the body is trying to clear the pathogens
- Sore Throat: The body's cells are damaged by the pathogens
- Fever: Another sign of the body's inflammatory response to infection
Causes of URT Infections
- Most common cause: Viruses, mainly rhinoviruses (also known as the common cold)
- Other viral causes: Influenza virus (flu), coronaviruses, adenoviruses and over 200 other viruses
- Bacterial causes: Usually streptococcus bacteria, mainly Streptococcus A
Transmission of URT Infections
- Hand-to-mouth contact: Touching the nose and mouth after contact with contaminated surfaces
- Airborne transmission: Droplets released through coughing and sneezing
Prevention of URT Infections
- Handwashing: Regular handwashing to remove pathogens
- Covering coughs and sneezes: Use your elbow or a tissue to contain droplets
- Vaccination: Flu vaccines can protect against influenza virus
Treatment of URT Infections
-
Viral infections: No specific treatment, the body's immune system must fight the virus
- Supportive care: Drink fluids, rest
- Bacterial infections: Antibiotics are prescribed by a doctor
Support Treatment
- Hydration: Replenishes fluids lost during illness
- Symptom relief: Throat lozenges, nasal spray
- Fever reduction: Acetaminophen (paracetamol or Tylenol) or ibuprofen (Advil, Motrin)
Conclusion
- Most URT infections are caused by viruses
- Viruses lack a specific treatment, the body's immune system must fight it
- The speaker's infection is caused by Streptococcus A, which is a bacterial infection requiring antibiotics
- Antibiotics only treat bacterial infections, not viral infections.
