This study investigated the trends of head louse infestation in the Republic of Korea over a 9-year period (2011-2019), targeting primary schoolchildren in 3 areas of Seoul, 4 other large cities, and 9 provinces. A survey was administered annually by the health staff of each regional office (&lt;i&gt;n&lt;\/i&gt;= 16) of the Korea Association of Health Promotion (KAHP). The branch offices of KAHP examined a total of 51,508 primary schoolchildren, comprising 26,532 boys and 24,976 girls. Over the 9-year survey, a total of 1,107 (2.1%) schoolchildren tested positive for adults and\/or nits of &lt;i&gt;Pediculus humanus capitis&lt;\/i&gt;. The prevalence was 2.8% (133\/4,727) in 2011-2012 and gradually decreased to 0.8% (49\/6,461) in 2019 (&lt;i&gt;P&lt;\/i&gt;&lt; 0.05). Head lice were found more frequently in girls (3.0%; 746\/24,976) than in boys (1.4%; 361\/26,532) (&lt;i&gt;P&lt;\/i&gt;&lt; 0.05). In terms of geographic localities, the highest infestation rate, 4.7% (average prevalence over 9 years), was observed in southern Seoul (Gangnam branch of KAHP), whereas the lowest infestation rate, 0.7%, was seen in Gyeongsang (north and south provinces) and western Seoul. Although the prevalence decreased significantly during the 9-year period, head louse infestation remains a health and hygiene issue among primary schoolchildren in the Republic of Korea. Regular surveys along with health education are needed to further improve children\u2019s hair
