Pharyngitis (sore throat) is a common condition that can be caused by bacteria or viruses.

Doctors only prescribe antibiotics to patients with pharyngitis if they are certain their infection is caused by bacteria. Write down two reasons why.

Look at the graph. It shows the percentage of patients showing symptoms of pharyngitis over time.

A line graph showing the percentage of patients with symptoms of pharyngitis over time. The vertical axis is labeled "Percentage of patients showing symptoms (%)" and ranges from 0 to 100. The horizontal axis is labeled "Time from onset of symptoms (days)" and has marked intervals at 0, 7, 14, and 21. A dashed line representing "Viral pharyngitis" starts at day 0, rises rapidly to a peak of 90% at day 3, and falls to 0% by day 7. A solid line representing "Bacterial pharyngitis" starts near 0, rises gradually to a peak of 80% at day 10, and falls back to 0% by day 21.

Doctors usually wait 777 days after the onset of symptoms before prescribing antibiotics for pharyngitis. Use the graph to explain why.
