Clinical Causes: Infection with rhinovirus, the primary virus responsible for the common cold Spread through airborne droplets when an infected person coughs or sneezes Contact with contaminated surfaces or objects and then touching the face Weakened immune system making the respiratory tract more susceptible to infection Exposure to cold weather or irritants that can impair airway defenses

Key Symptoms: Persistent cough, which may produce mucus Mild shortness of breath or wheezing Sore throat and nasal congestion Mild fever or chills Fatigue or a feeling of general discomfort Chest discomfort or tightness

Diagnosis Path: Diagnosis of acute bronchitis due to rhinovirus is usually based on medical history and physical examination. Healthcare providers look for characteristic symptoms such as cough and congestion. Laboratory tests, including viral cultures or PCR (polymerase chain reaction) testing, can detect rhinovirus as the underlying cause. In some cases, a chest X-ray may be recommended to rule out other respiratory conditions like pneumonia.

Treatment Protocols: Rest and adequate fluid intake to support immune function Over-the-counter medications such as cough suppressants or pain relievers to ease discomfort Use of humidifiers or saline nasal sprays to relieve congestion Avoiding irritants like smoke or pollutants that can worsen symptoms Monitoring symptoms and seeking medical care if they worsen or do not improve within a few weeks
