Management of Persistent Cough Post-URTI in Children

Assessment and Management Approach

Post-viral cough is a common cause of persistent cough in children, often lasting 1-3 weeks after a URTI, with 10% of children still coughing at 25 days, according to the American College of Chest Physicians 1, 3
The American College of Chest Physicians recommends watchful waiting as the primary approach for post-viral cough, as it is likely to resolve spontaneously within 1-2 weeks 1, 2
Reassure parents that post-URTI cough can persist for up to 4 weeks in children without indicating a serious condition, as suggested by the American College of Chest Physicians 1, 3
Avoid empirical trials of asthma medications unless there are other features consistent with asthma, such as recurrent wheeze or dyspnea responsive to beta-2 agonists, as recommended by the American College of Chest Physicians 2, 6
If cough persists beyond 4 weeks, further evaluation is warranted, including consideration of chest radiograph and spirometry, according to the American College of Chest Physicians 2
Consider pertussis testing if cough becomes spasmodic or is associated with post-tussive vomiting, even in vaccinated children, as partial vaccine failure can occur, as suggested by the American College of Chest Physicians 1, 3
Review in 1-2 weeks if cough persists, and advise parents to return sooner if cough worsens significantly, new symptoms develop, or sleep or daily activities become significantly disrupted, as recommended by the American College of Chest Physicians 2, 5
