A community survey records information about three participants.
| Participant | Disease recorded | Other information |
|---|---|---|
| R | None | Reports high stress and difficulty coping with the normal demands of everyday life |
| S | Influenza | None |
| T | Type 2 diabetes | None |
Explain why the survey should not classify R as being in good health solely because no disease was recorded.
Explain why the disease recorded for S can be passed from one person to another but the disease recorded for T cannot.
