Most people with SARS develop pneumonia. Breathing problems can become so severe that a mechanical respirator is required. SARS is fatal in some cases, often due to respiratory failure. Other possible complications include heart and liver failure.

People older than the age of 60 — especially those with underlying conditions such as diabetes or hepatitis — are at highest risk of serious complications.
