Understanding & Identifying an Upper Respiratory Infection
While most of us are familiar with the sniffles and sore throat that accompany simple upper respiratory infections like the common cold, we're here to share some additional information on other infections that can affect your respiratory tract.
What is an Upper Respiratory Infection?
An upper respiratory infection is a viral or bacterial infection affecting one or several areas of your upper respiratory tract. This can include your sinuses, epiglottis, lyryx, and your bronchial tubes. The part of your respiratory tract that is affected determines what type of URI you have.
The types of upper respiratory infections include:
- The common cold
- Sinusitis
- Epiglottitis
- Laryngitis
- Bronchitis
What Can Cause a URI?
When it comes to upper respiratory infections, they can be brought on by both viruses and bacteria.
Viruses that can cause a URI include:
- Adenovirus
- Coxsackievirus
- Parainfluenza virus
- Rhinovirus
- Influenza viruses
Bacteria that can cause a URI include:
- Chlamydia
- Gonorrhea
- Diphtheria
- group A beta-hemolytic streptococci
- group C beta-hemolytic streptococci
Signs & Symptoms
Some of the most commonly experienced symptoms of an upper respiratory infection include:
- Body aches
- Cough
- Fatigue or tiredness
- Fever
- Pain while swallowing
- Nasal congestion
- Runny nose

Key Symptoms to Watch For
When dealing with an upper respiratory infection, it’s important to recognize signs that may indicate a more serious condition. A high fever—especially one over 103°F (39.4°C) that doesn’t go away—can signal a more severe infection and should prompt medical attention. Difficulty breathing, such as shortness of breath, wheezing, or chest pain, also warrants immediate care, as these symptoms may point to a serious respiratory issue.
Be alert to worsening symptoms. If you initially start to feel better but then suddenly feel worse, this may suggest a secondary bacterial infection, which requires evaluation by a healthcare provider. Additionally, if your symptoms persist for more than 10 days without improvement, it could indicate a more serious illness and should be assessed by a doctor.
Other concerning symptoms include severe headache or facial pain, which may be related to sinusitis or other complications that require treatment. Likewise, ear pain—especially if accompanied by a fever that doesn’t resolve within two days—may be a sign of an ear infection and should be evaluated by a medical professional.
Additional Considerations
Certain groups, such as young children, the elderly, and individuals with weakened immune systems, are at higher risk for complications and should seek medical care sooner if symptoms arise. In emergency situations—such as experiencing confusion, extreme drowsiness (lethargy), or significant difficulty breathing—it is critical to seek immediate medical attention.
By staying alert to these warning signs and knowing when to seek help, you can ensure timely and appropriate care during an upper respiratory infection. Always prioritize your health and don’t hesitate to consult a healthcare provider if you have any concerns.
