Differential Diagnosis for Alexia
- Single most likely diagnosis
- Viral upper respiratory tract infection (URTI): This is the most likely diagnosis given the symptoms of dry, coarse cough, sinus congestion, and a mild temperature elevation. The improvement and subsequent worsening of symptoms are also consistent with a viral URTI.
- Other Likely diagnoses
- Acute bronchitis: The persistent cough and sinus congestion could be indicative of acute bronchitis, especially if the cough is productive.
- Allergic rhinitis: The symptoms of sinus congestion and cough could be related to allergies, especially if Alexia has a history of allergies or if the symptoms are seasonal.
- Sinusitis: The sinus congestion and cough could be indicative of sinusitis, especially if the symptoms persist or worsen over time.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Pneumonia: Although the symptoms are mild, pneumonia is a potentially life-threatening condition that requires prompt diagnosis and treatment. The increased heart rate and respiratory rate are concerning signs that warrant further evaluation.
- Pertussis (whooping cough): This highly contagious and potentially serious illness can present with a persistent cough, especially in children who are not fully vaccinated.
- Epiglottitis: This rare but life-threatening condition can present with a severe sore throat, cough, and difficulty breathing.
- Rare diagnoses
- Cystic fibrosis: Although rare, cystic fibrosis can present with recurrent respiratory infections and persistent cough.
- Foreign body aspiration: This is a rare but potentially life-threatening condition that can present with sudden onset of cough and respiratory distress.
- Tuberculosis: Although rare in children, tuberculosis can present with a persistent cough, fever, and weight loss.
