*3.2. Perceived Risk, Risk Factors and Preventive Knowledge about COVID-19*

The students analyzed showed a medium-high perception of risk of COVID-19 infection (67.2%), with a greater weight of extrinsic factors (FR1, 75.6%) than intrinsic factors (FR2, 56.9%). Those who stated that someone in their close environment had suffered from COVID-19 scored significantly higher. Those who had experienced COVID-19 scored significantly higher on FR1 (extrinsic), and those who had not suffered COVID-19 scored higher on FR2 (intrinsic). Intrinsic factors scored differently depending on the academic year. The score obtained on the knowledge scale, which reached a high level in the general population (54.25 +/− 4.95 out of 60), was significantly higher in women and in those in more senior years (Table 2).
