Consider chest x ray (single frontal projection) for patients with:
• Increased work of breathing
• Persistent tachypnoea
• Sp02 <92% on room air
• Temperature > 39˚C and white cell count >20
Note that underlying co-infection may be more common in paediatric patients.
Covid-19 infection may be impossible to differentiate clinically from many other childhood respiratory illness.
Always wear appropriate PPE.
