Symptoms of acute bronchial infection

The incubation period varied from 1 to 3 days, and varied with viruses. Enterovirus was the shortest, adenovirus and respiratory syncytial virus were the longest. The onset was sudden. Most of them had burning sensation in the nose and throat, followed by nasal congestion, sneezing, runny nose, general discomfort and muscle soreness.

Symptoms reached the peak at 48h (virus shelling). Acute nasopharyngitis usually had no fever or only low fever, especially when infected with rhinovirus or coronavirus. May have conjunctival congestion, tears, photophobia, eyelid swelling, pharyngeal and laryngeal mucosal edema. Laryngopharyngitis and tracheitis vary from person to person and from virus to virus. Nasal secretions were initially watery and clear, and then became mucinous or purulent.

Mucopurulent secretion does not necessarily indicate secondary bacterial infection. Cough is usually mild and lasts up to 2 weeks. Purulent sputum or severe lower respiratory symptoms suggest that viruses other than rhinoviruses are associated with or secondary to bacterial infection. When children have a cold, their symptoms are more severe than those of adults. They often have lower respiratory tract symptoms and digestive tract symptoms (vomiting, diarrhea, etc.). Most colds are self limited. If there are no complications, the course of disease is 4-10 days.
