Summary about Disease
Coryza, commonly known as the common cold, is a mild, self-limiting viral infection of the upper respiratory tract, primarily affecting the nose and throat. It is characterized by nasal congestion, runny nose, sneezing, and sore throat. While generally harmless, it can cause discomfort and disrupt daily activities.
Symptoms
Common symptoms include:
Runny nose (initially clear, may thicken later)
Nasal congestion
Sneezing
Sore throat
Cough
Mild headache
Low-grade fever (more common in children)
Fatigue
Watery eyes
Causes
Coryza is primarily caused by viruses, most commonly rhinoviruses. Other viruses, such as coronaviruses, adenoviruses, and respiratory syncytial virus (RSV), can also cause the common cold. The virus enters the body through the nose, mouth, or eyes, usually after contact with contaminated surfaces or infected individuals.
Medicine Used
Treatment for coryza focuses on relieving symptoms. Common medications include:
Decongestants (oral or nasal sprays)
Pain relievers (acetaminophen, ibuprofen) for fever and aches
Antihistamines (to reduce sneezing and runny nose, but may cause drowsiness)
Cough suppressants or expectorants
Nasal saline drops or sprays
Zinc lozenges (may shorten duration if taken early, consult with a doctor) Important Note: Antibiotics are ineffective against viral infections like coryza and should not be used unless a secondary bacterial infection develops.
Is Communicable
Yes, coryza is highly communicable. It spreads through:
Airborne droplets produced by coughing or sneezing.
Direct contact with infected individuals.
Contact with contaminated surfaces (e.g., door handles, phones) followed by touching the face.
Precautions
To prevent the spread of coryza:
Wash hands frequently with soap and water.
Avoid touching your face (eyes, nose, mouth).
Cover your mouth and nose when coughing or sneezing (use a tissue or your elbow).
Stay home when you are sick.
Avoid close contact with infected individuals.
Disinfect frequently touched surfaces.
How long does an outbreak last?
The typical duration of a coryza outbreak (common cold) is 7 to 10 days. Some symptoms, such as a cough, may persist for up to 2-3 weeks.
How is it diagnosed?
Coryza is usually diagnosed based on symptoms and a physical examination. Lab tests are typically not required for uncomplicated cases. However, in some situations (e.g., during a pandemic or to rule out other illnesses like the flu or COVID-19), a nasal swab may be taken to identify the specific virus.
Timeline of Symptoms
Day 1-3: Sore throat, fatigue, sneezing, runny nose (clear discharge)
Day 4-7: Nasal congestion, cough, possible low-grade fever, thicker nasal discharge
Day 7-10: Symptoms gradually improve, cough may linger
Important Considerations
Children: Young children, especially infants, may develop higher fevers and are more prone to complications. Consult a doctor if a child has a high fever, difficulty breathing, or other concerning symptoms.
Underlying conditions: Individuals with asthma, chronic obstructive pulmonary disease (COPD), or weakened immune systems may experience more severe symptoms or complications.
Differentiation from the flu (influenza): The flu often presents with more severe symptoms, including high fever, body aches, chills, and fatigue, compared to a typical cold.
When to see a doctor: Seek medical attention if symptoms are severe, do not improve after 10 days, or if you develop shortness of breath, chest pain, high fever, or dehydration.
