Frequently Asked Questions

❓ What are the most common respiratory infections in children?
Common respiratory infections in children include croup, acute epiglottitis, bronchiolitis, pneumonia, atypical pneumonia, pneumococcal pneumonia, and staphylococcal pneumonia. These infections affect different parts of the respiratory tract and vary in severity from mild viral illnesses to life-threatening airway obstruction.
❓ What causes croup in children?
Croup is usually caused by viral infections, most commonly parainfluenza virus type 1. Other viruses include respiratory syncytial virus, influenza virus, adenovirus, and human metapneumovirus. The infection leads to inflammation and narrowing of the subglottic airway.
❓ What are the classic symptoms of croup?
The classic symptoms of croup include a barking seal-like cough, inspiratory stridor, hoarseness of voice, and mild fever. Symptoms often worsen at night and may be accompanied by respiratory distress.
❓ How is acute epiglottitis different from croup?
Acute epiglottitis is a severe bacterial infection usually caused by Haemophilus influenzae type b. It presents with high fever, drooling, severe sore throat, muffled voice, and tripod posture. Unlike croup, epiglottitis progresses rapidly and can cause sudden airway obstruction.
❓ What is bronchiolitis in infants?
Bronchiolitis is a viral infection of the small airways in infants and young children. It is most commonly caused by respiratory syncytial virus and results in inflammation, mucus production, wheezing, and respiratory distress.
❓ What are the common symptoms of bronchiolitis?
Symptoms of bronchiolitis include cough, wheezing, tachypnea, feeding difficulty, nasal congestion, crackles on lung examination, and sometimes apnea in severe cases.
❓ What organisms commonly cause pneumonia in children?
Common causes include Streptococcus pneumoniae, Mycoplasma pneumoniae, Staphylococcus aureus, Haemophilus influenzae, and respiratory viruses such as RSV and influenza virus.
❓ What is atypical pneumonia in children?
Atypical pneumonia is usually caused by organisms such as Mycoplasma pneumoniae or Chlamydia pneumoniae. It presents with persistent dry cough, mild fever, headache, and diffuse interstitial infiltrates on chest X-ray.
❓ What complications can occur in staphylococcal pneumonia?
Staphylococcal pneumonia can cause severe complications including lung abscess, pneumatocele formation, empyema, pneumothorax, and necrotizing pneumonia.
❓ How are respiratory infections in children usually treated?
Treatment depends on the cause and severity. Viral infections such as bronchiolitis and croup are mainly treated with supportive care, oxygen, and corticosteroids when indicated. Bacterial pneumonias require antibiotics such as amoxicillin, ceftriaxone, or macrolides depending on the organism.
