Natural History Adapted from Mandell, Douglas, and Bennett's Principles and Practice of Infectious Diseases[1]
- Patients usually develop symptoms 1 week after the contact with a symptomatic patient.
- The first 2-3 days the patient presents mild upper respiratory symptoms (cough, rinorrhoea and low fever).
- Acute pahse (shortness of breath, wheezing, persistent prominent cough, tachypnea, chest wall retraction and nasal flaring) usually developes between the third and seventh day.
- Symptoms gradually disapear within the next 2 weeks (the cough may take longer)
Complications
- Airway disease, including asthma, later in life
- Respiratory failure
- Additional infection, such as pneumonia
Prognosis
Usually, the symptoms get better within a week, and breathing difficulty usually improves by the third day. The mortality rate is less than 1%.
