This study hypothesized that national population health literacy might reflect on their keywords searching. We applied Google searches for "wash hands" and "face mask" during January 19 to February 18 as a surrogate of national population health literacy among 21 countries, and examine whether google searches for "wash hands" and "face masks" would protect from increased numbers of confirmed cases of among 21 countries We found the increased google searches for "wash hands" from January 19 to February 18, 2020, correlated with a lower spreading speed of COVID-19 from February 19 to March 10, 2020 among 21 countries (Pearson's correlation coefficient of -0.70, P < 0.001). The result highlights the importance of public awareness of hand washing in preventing COVID-19 disease spreading.
本研究假设，国民健康素养水平可以反映在他们的关键词搜索上。我们在 2020 年 1 月 19 日至 2 月 18 日期间应用谷歌搜索“洗手”和“口罩”，以此作为 21 个国家人口健康素养的替代指标，并检验谷歌搜索“洗手”和“口罩”是否能降低 21 个国家的确诊病例数量。我们发现，2020 年 1 月 19 日至 2 月 18 日期间谷歌搜索“洗手”的次数增加，与 2020 年 2 月 19 日至 3 月 10 日期间 21 个国家 COVID-19 的传播速度下降呈正相关（皮尔逊相关系数为-0.70，P<0.001）。结果强调了公众对手部卫生的认识在预防 COVID-19 疾病传播中的重要性。
