The prevalence of scabies is the higher in environment with the higher density and the poor sanitation. This research aims to study a correlation between environment sanitation and personal hygiene with the scabies incident at Rutan (detention center) branch of Sibuhuan, regency of Padang Lawas.

The results of study indicates that environment sanitation variable, i.e. the floor condition (p = 0,001) has a correlation to the scabies incident. The variable of ventilation, humidity, lighting and availability of pure water are not considered because fulfill requirement by the density of the detention center did not fulfill the health requirement. The personal hygiene variable, i.e. genital cleanness (p = 0,029) and clothes and towel cleanness (p = 0,014) has a correlation to the scabies incident. While the skin and hair cleanness variables (p = 0,286), the hand, foot and nail cleanness (p = 0,636) and the cleanness of bad and bad cover (p = 0,654) has not a correlation to the scabies incident.
