 Pediculosus capidus is a common skin condition that primarily affects children. During the COVID-19 pandemic, various restrictions were implemented worldwide, including in Poland. This study assessed the effect of these restrictions on the prevalence of head lice infestation among school and kindergarten attendees in Poland. Results showed that the restrictions decreased the number of children infested with head lice compared to pre-pandemic data. This suggests that head lice infestations remain an ongoing epidemiological concern and should be monitored.
