Upper Respiratory Infections

What Is an Upper Respiratory Infection?

An upper respiratory infection affects the nose, throat, sinuses, and airways. Most URIs are caused by viruses, though bacteria may be responsible in some cases. URIs are contagious and spread easily through coughing, sneezing, or close contact. Click here to learn more about the illnesses we treat at our walk-in clinics. 

Types of Upper Respiratory Infections

There are several types of URIs, each with slightly different symptoms and causes:

• Common Cold (Rhinitis): Usually caused by viruses such as rhinovirus and presents with runny nose, congestion, and cough.
• Pharyngitis (Sore Throat): Inflammation of the throat, often viral but sometimes bacterial (e.g., strep).
• Sinus Infection (Sinusitis): Inflammation or infection of the sinus cavities, causing facial pain, pressure, and congestion.
• Influenza (Flu): A systemic viral respiratory infection that can present with fever, body aches, cough, and upper airway symptoms — an important seasonal cause of urgent care visits.
• Tonsillitis: Swollen, painful tonsils from viral or bacterial infection.
• Laryngitis: Inflammation of the voice box leading to hoarseness or loss of voice. Medscape

Common Symptoms of a URI

Symptoms vary depending on the type of infection but may include:

• Runny or stuffy nose
• Sore or scratchy throat
• Coughing or sneezing
• Pain when swallowing
• Nasal congestion and sinus pressure
• Fatigue or body aches
• Low-grade fever (more common in children)

If symptoms last more than two weeks, suddenly worsen, or are severe, it’s best to seek medical care.
