We use evidence from randomised controlled trials to answer practical questions on the prevention, treatment and diagnostic test accuracy of acute respiratory infections. This includes infections from the nasal tract, pharynx, larynx, trachea, lungs and bronchus.

We produce and update reviews of interventions and diagnostic test accuracy for the prevention, treatment and diagnosis of acute respiratory infections such as:
acute otitis media (middle ear infection)
bronchiolitis
bronchitis
common cold
COVID-19
croup
diphtheria
glandular fever
herpes zoster (shingles)
influenza
laryngitis
Legionnaire’s disease
measles
meningitis
mumps
pertussis (whooping cough)
rubella (German measles)
SARS
sinusitis
pharyngitis and tonsillitis (sore throat)
pneumonia
varicella (chickenpox)
