Increases in COVID-19 symptom-related searches preceded increases in reported COVID-19 cases and deaths by an average of 18.53 days (95% CI 15.98–21.08) and 22.16 days (20.33–23.99), respectively.
My contention is that Pinterest is one of the four ways that people find things on the Internet. The default, of course, is Googling (or—fine, Microsoft—Binging).
