The impact of national social distancing on the spread of common respiratory virus infections has rarely been investigated. We evaluated the weekly proportion of negative respiratory virus polymerase chain reaction (PCR) test results and weekly positive rates of each respiratory virus during the social distancing period (10th\u201341st weeks of 2020) and the corresponding period in different years, utilizing the national respiratory virus surveillance dataset reported by the Korean Center for Disease Control and Prevention. The proportions of negative respiratory virus PCR test results increased up to 87.8% and 86.1% during level 3 and level 2 of the social distancing period, respectively. The higher the level of social distancing, the higher the proportion of negative respiratory virus PCR test results. During the social distancing period, the mean weekly positive rates for parainfluenza virus, influenza virus, human coronavirus, and human metapneumovirus were significantly lower than those during the same period in 2015\u20132019 (0.1% vs. 9.3%,\n                    <jats:italic>P<\/jats:italic>\n                    &lt;0.001; 0.1% vs. 7.2%,\n                    <jats:italic>P<\/jats:italic>\n                    &lt;0.001; 0.4% vs. 2.3%,\n                    <jats:italic>P<\/jats:italic>\n                    &lt;0.001; and 0.2% vs. 5.3%,\n                    <jats:italic>P<\/jats:italic>\n                    &lt;0.001, respectively).
